Bass.EXE

"Navis have no need for operators. All that we need is the strength to exist on our own! Absolute power, so that we need cower before none. I will weed out weak Navis who cannot fight on their own!"

- Bass.EXE

"Pathetic weakling! Return to the 0's and 1's you're made of!"

- Bass.EXE

"......Of course. Battle is my forte!"

Bass.EXE, known as Forte.EXE in Japan, is a NetNavi from the Mega Man Battle Network series.

Background
Bass.EXE is a mysterious and solitary NetNavi. He was first created by Dr. Cossak as part of SciLab's project to develop a new generation of independent NetNavis that do not need an operator and can get abilities from viruses and Navis. This is what makes him one of the most deadly Navis in existence.

Bass was blamed for disrupting the Net and was attacked by officials, when in actuality, Alpha was the cause. He survived this attack and used his Get Ability program to keep himself alive and become stronger until he could get his revenge on the humans.

Mega Man Battle Network
Eventually, he stole the Life Aura data from the remnants of the defeated Dream Virus (the first game's final boss) and encountered MegaMan on the Net, but was defeated.

Mega Man Network Transmission
Bass appears as an hidden boss in this game. In order to fight him, the player must have obtained every Navi Chip in the game (except for the Bass Navi Chip). This can be done through the Net Battle Simulator, and requires the player having met the requirements for the good ending, as that is the only way to obtain the Zero Navi Chip. Once that has been done, Lan receives an email from Mayl about a "secret area" in Den Area 3 where a powerful Navi is found. This is where the player can find Bass. There is no way to defeat Bass, but once his HP is low enough, Bass throws off his cloak, the fight ends, and the player earns the Bass battle chip.

Mega Man Battle Network 2
This time, he played a larger role in the plot, where the Gospel Netmafia was trying to clone him through the use of BugFrags. Initially, it seemingly produced a perfect copy of Bass, although it proved to not be completely perfect due to MegaMan.EXE defeating the copy easily. Gospel's leader (revealed to be Sean), however, was unwilling to give up, and decided instead to max out the servers capacity to 200%, not caring if he ended up killed by the intense radiation in the process. This failed, and the clone mutated into the giant Gospel Megavirus. The monster overcharged the server to 600% before MegaMan could destroy it. He also appears after the credits of the game, where he destroys a Bass clone and states that he is angry at Sean for attempting to clone him. He roams looking for strong enemies to fight while never fighting for WWW. He then finds his match in Mega Man where he is defeated, saying that he is impressed. He also leaves a Bass chip behind.

Mega Man Battle Network 3
As well as being implied in the previous game, it was later revealed that Wily had been behind everything, and was trying to copy Bass in order to free Alpha. Wily allied himself with Bass, who helped steal Alpha's data and the TetraCodes. In exchange, Wily proposed to give Bass the power to attack the humans. Prior to the climax of the game Bass notices MegaMan and challenges him after his battle with FlameMan. Because FlameMan got in his way, Bass swatted him aside since he wanted to fight MegaMan himself.

To his disappointment, MegaMan provided no challenge (he is actually fought at that point game, but is impossible to defeat because he can't be damaged). Just as Bass was about to finish MegaMan, one of the Official NetNavis appeared to protect him by using the Dark Aura. Goaded by the boasts of its power, Bass attacked the Navi and

the Dark Aura barely withstood his power. Bass likely would've finished him off if Wily hadn't called him away. Later, Bass aided in freeing Alpha. When MegaMan tried using the GigaFreeze program, Bass revealed that he could control it and stopped it.

At the climax of the game, Bass reveals his past to everyone - he was initially created by Cossak, but was blamed for the incidents caused by Alpha, and was left to wander through the Undernet, with a scar across his body and a grudge against humans. Bass then smashed and absorbed the Guardian program, which was the last thing keeping Alpha sealed away. Bass is then fought and defeated by MegaMan (this is the only time that Bass is fought in a battle that's part of the storyline). Wily betrayed Bass and let Alpha swallow Bass, but got eaten as well.

After Alpha's destruction, Bass was near death, but found by a remnant of the Gospel Multibug Organism, who merged with Bass and saved his life, forming Bass GS. After Serenade's defeat, Serenade mentioned that the only other Navi who could defeat him was Bass. Bass GS consumed at least 300 BugFrags, courtesy of MegaMan, and attacked MegaMan to test this new power. After a close battle, Bass lost, and it is revealed that he had lost most of his memory while fused with Gospel. He then vanishes from the Secret Area.

Mega Man Battle Network 4
Bass resurfaced in the Undernet, and later Black Earth. MegaMan accidentally woke the Dark Messiah, who attacked MegaMan wielding the power of the Dark Chips. Bass lost again, and fled to Black Earth where he fought MegaMan one last time after the defeat of the Dark Soul Navis.

Mega Man Battle Network 5
When MegaMan gained the power of Bass (Bass Cross MegaMan), Bass feels his power, then reappears and challenges MegaMan at a secret corner of the Net. He lost, then fled to Nebula Area and challenged MegaMan a second time. This time, Bass's soul has been consumed by the darkness and became "Bass Alpha". Finally, Bass could be encountered as the Chaos Lord, an amalgamation of the Dark Power in the deepest part of Nebula Area, but with no dark power inside. After defeated as the Chaos Lord, he can be found randomly as Bass XX, the most powerful boss in the game. But he's defeated again, admitted he was too weak and left to become more powerful.

Mega Man Battle Network 6
Having challenged MegaMan in both the Undernet and the secret Graveyard zone, he went to the Underground, former prison of the Cybeasts, and absorbed their data fragments and gaining the power of the Cyber Beast of the opposing version. After forcing MegaMan to fight a clone of Beast-Out MegaMan, Bass moved in for the kill, but was defeated. It is unknown if he survived the last battle, although Lan suggests so by convincingly saying "Bass is Bass". His survival later proves true, as from his final defeat onward, he can be found at the Graveyard as a random encounter.

In each game he appears in, Bass's final form is the hardest boss in the game. Bass usually has a unique "form identifier". Where most Navis would be 1-2-3 or normal-EX-SP, Bass's ultimate forms have been, variously, Bass DX, Bass GS, Bass XX and Bass BX amongst others. Bass is the most powerful Navi, capable of easily defeating many strong Navis.

MegaMan NT Warrior
In the anime, he and Gospel were created from data of PharaohMan by Lord Wily. As Wily explains Bass came to exist from the left over data of PharaohMan that Wily didn't use to make Gospel. Also while Gospel contains PharaohMan's ultimate program; Bass on the other hand is the reincarnation of PharaohMan's soul but lacking any memories which where used in making Gospel. At first he has no memories and wanders the Net in a curious, confused state.

Also because he was made from fragments of another Navi he has an almost virulent hunger and consumes raw data to replenish the missing code, as shown when MegaMan saw him consuming raw data in the form of an energy ball. Despite this he doesn't attack Navis and seems to feed almost on instinct. However when Gospel attacked the Net, he got in its way and made it leave. Part of him also senses the connection between himself and Gospel which draws him to the beast. He later kidnaps MegaMan in order to find out who he really is. Bass reads MegaMan's mind and learns about

his origins.

After that, he attacks Gospel and initially defeats him. Bass tries to absorb him so that they could become one again and gain his powers but Gospel is too strong and Bass's data disperses and is absorbed himself. After Gospel's destruction, Lord Wily was baffled to see that BugStyle MegaMan had actually rebuilt the whole Network including all data absorbed by Gospel when Kid Grave suddenly gets back up. The robot is possessed by Bass and he walks away after proclaiming that he'd use it to conquer both worlds.

Despite the fact Bass doesn't have all of PharaohMan's powers, he was still incredibly strong with a multitude of abilities including teleportation, energy blasts, regeneration, absorption and many other powers. He also possessed the ability to shrug off fatal attacks, like when FreezeMan impaled him and then froze him solid; both attacks did nothing and Bass responded by breaking the floor beneath FreezeMan without having to move an inch. He showed no ill effect from the attacks either.

He also appeared to possess some kind of a telepathic link with MegaMan, or at least some kind of extrasensory awareness of MegaMan, which might have something to do with the fact he once had an ultimate program like MegaMan.

Also contact with MegaMan caused the dormant virus that originally infected PharaohMan to transfer to a new host since Bass no longer had the Ultimate program; leading to MegaMan's Bug style rampage.

MegaMan NT Warrior Axess
In Axess, his appearances are short. He appears once in his Kid Grave body when Lan and his friends cornered Allegro. He claims that Allegro was a robot he created in order to develop Dimensional Areas so as to allow solo NetNavis like him to enter the real world, but was disappointed with the end result and destroyed him. He reappears in the pit where ShadeMan was trapped when he was overthrown by LaserMan and shatters the tomb he is in, freeing him. He declares that he is a Darkloid and supports the true solo data beings. He then watches the battle between ShadeMan and Dr. Regal and LaserMan Cross Fused but leaves when he realizes ShadeMan lost.

Rockman.EXE Stream
In Stream, he plays a more prominent role. He is seeking power; and attempts to kidnap MegaMan for his Ultimate program, but is forced to retreat when ProtoMan joins the battle. He appears again in the Outer Space Development Center to try and infiltrate Duo.EXE's comet at the same time MegaMan and ProtoMan were going to do so, but is defeated by Slur pretty badly and is banished to the Undernet.

He is last seen in a battle against Slur, at the end of Stream. This time, it is implied that he has absorbed the remnants of Nebula Grey, and uses it's power to defeat Slur without a scratch (he also makes a remark to MegaMan stating that 'his' world was safe for the time being before logging out). Although he doesn't reappear in Beast, it is implied he is still alive and wishes to take no more action in the present and just wants to settle down, unlike the games where he continuously attacks MegaMan for "revenge", as he claims.

Rockman.EXE: Program of Light and Dark
He resurfaces in the movie and initially fights against MegaMan because Dr. Regal manipulated him, but tries to kill Regal for doing so once he realizes it. He and MegaMan team up to fight Nebula Grey, but they are defeated. However, MegaMan gives Bass his Ultimate Program and both Navis fuse and, forming the synchronized Bass Cross MegaMan, which promptly proceeds to defeat Nebula Grey effortlessly with tremendous power. After its defeat, Dr. Regal opens a portal to try and delete the heroes. Before they are sucked into the portal, Bass fires an energy blast at MegaMan which forces him to jack out. Bass is then drawn into the vortex, laughing maniacally.

Appearance
As with his original counterpart, Bass.EXE appears to resemble an elaborately darker version of MegaMan.EXE. He looks almost identical to his original counterpart, but his cobra-like helmet has been altered as the "fins" are mostly straightened out and split off at the bottom to show off a second pair of smaller fins. Golden shoulder pads are also adorned on his body as well.

The chest jewel that was present in the original version is replaced with his emblem, a solid black circle with no features or characteristics, but a white scar is embedded across it diagonally. Bass.EXE's most famous characteristic however is a long flowing light brown cloak that usually covers the lower portion of his face as well as the rest of his body, which invokes a vagrant appearance.

Though his original emblem is never displayed, it has been believed that the symbol would be similar to the jewel on his forehead. The origin of the scar on his emblem was revealed to caused by a fire sword battle chip used by a si-lab security navi.

Hub-Style (Manga Only)

After copying Hub-Style in his battle with MegaMan.EXE he takes on similar features to MegaMan.EXEs Hub-Style. Including what appears to be a data streaming flowing all over his body. Also like MegaMan.EXEs Hub-Style he has two flat rings of light circling around him. However in one illistrated picture it has shown that the data stream on Bass.EXEs body is purple, rather then green like MegaMan.EXE.

Beast-Out Falzar (Manga Only)

Unlike MegaMan.EXE who used Double Soul to trigger Beast-Out, Bass.EXE forced his transformation by using his Get Ability Program to abosorb data from a weakened Falzar. In this form the top two fins on his head change and have a beak like shape, his long cloak is reduced to a scarf that covers his neak and mouth, his hands and feet change to the equalvilant versons of MegaMan.EXEs hands and feet during Falzar Beast-Out, he also gains wings similar to Falzars, and finally the crest on his head now changes to the symbol of Flazar.

Personality
Bass's personality is added to during the first three games. In the first game, nothing is known about him. In the second game, because Bass is still only briefly seen, not much is seen about him. What is shown is that due to his own pride, he hates anybody that would try to create copies of him and his disdain towards humans. After his battle with MegaMan, he displays shock and interest in that MegaMan could hurt him and leaves. This battle and some events in the third game indicate that Bass likes fighting, but he's only interested in stronger opponents.

The third game reveals far more about him. Because Bass felt betrayed by humans, he grew to hate them and longed for revenge. He displayed no sense of loyalty as well. When he first wanted to fight MegaMan, even though Bass was working with Wily; he attacks FlameMan, one of his "ally's" subordinates. After being freed from Alpha, Bass has no memory of his past but retains his interest in fighting which causes him to continue to challenge MegaMan. But still, sometimes he assists MegaMan, mostly in the anime.

It's believed that there is still good in him. The only one he ever cared about was his "father" Dr. Cossak, but after his creator abandoned him, it broke Bass's heart making him what he is now. Although he believed that Dr. Cossak betrayed him, in the end he didn't have the heart to hurt him during their reunion. Because of his odd way to change roles depending on the situation he is in, his personality is more of an anti-hero based but his ego seems to always get the best of him and uses fighting as a resort to any means necessary.

To Bass, if there is a problem that bugs him, he blows it up. End of story, end of problem. So, he finds it either interesting, annoying, or frustrating if he can't blow the problem up (like MegaMan) so he'll keep an eye on the problem. Bass puts his own survival before anything else because basically, for the last ten years of his life, that's all he did. Survive, little else, and hate humanity for what they did to him.

In the second game (being the first where he has dialogue), Bass is shown to speak in an intellectual and formal yet surprisingly polite manner. In the third game he drops the politeness altogether but retains his verbose, analytical rhetoric, giving off an aloof and distant matter-of-fact vibe. This aspect of his personality is greatly downplayed in the last three games - possibly due to his dialogue being more limited and less relevant to the main plot - he also starts to speak in a more colloquial manner like most other characters. He notably becomes more aggressive and hotheaded in the sixth game, much more eager to hurl taunts at MegaMan than to praise him.

In Mega Man NT Warrior manga, Bass's personality is not much different from the original, though both his good side and bad side are balanced as the story progress. He's fully confident with his own power and likes to fight and constantly challenge strong opponents that warrant his attention to see does his opponent able to satisfy his anger and hatred, as shown when he spared MegaMan instead of deleting him during their first encounter in hope he'll become strong enough to fight him again. He looks down on those whom he views as weak, referring them as trashes and won't hesitate to destroy those who get in his way. He also has strong sense of pride, as shown when he didn't delete ProtoMan when the latter was defenseless due to Double Soul with MegaMan and opted to defeat MegaMan fairly with his own strength eventhough he could win easier that way. Due to his past, he believed that friendship and bonds of people are worthless and the only thing necessary to become strong is anger and hatred. This, however, seemed to change when he was defeated by MegaMan for a second time, as he acknowledged MegaMan's strength and determination, finally allowing himself to have a bond with someone for the first time. Since then, Bass developed a strong rivalry with him to the point both nearly deleted when each tried to save one another because of the promise they made to fight each other again (Bass saved MegaMan when Dark MegaMan tried to attack MegaMan, which caused him being captured by the Darkroids. And MegaMan was nearly deleted when he protected Bass from Nebula Gray until Bass absorbed him in order to save his life). During the last battle against the combined Grega and Falzer, Serenade stated that MegaMan is Bass's one and only true friend. Hearing this, Bass, denied the statement, saying that he's his nemesis before giving all of his power to MegaMan and told him to win, showing that he has confidence and faith in MegaMan's power.

The Battle Story Rockman.EXE manga version of Bass is somewhat different than what he is usually portrayed in the games and Mega Man NT Warrior anime, for the fact that it explores more of his good side. He was created years ago to maintain network energy, and to improve system functions/ in si-lab systems. He to be very powerful in the beginning. The power he possesses causes him to go crazy and destroy everything in his path, somewhat similar to how he acts in other media. However, it is that power that made Bass realize that he is a threat to the Cyberworld. Not wanting to harm anyone, he willingly seals himself away. He is also shown to be polite, even addressing himself in Japanese as "watashi" (わたし) rather than "ore" ( おれ - though he uses "ore" when the power he possesses overwhelms him), and is good friends with ShadowMan.EXE.

Forms
Normal Forms
 * Bass: This is the basic form, when he is first encountered in each game. In Mega Man Battle Network, the player must perform certain conditions and go to Internet Area 16. Bass in that game, is immensely powerful. His attacks are substantial and dangerous, inflicting an extreme amount of damage. Battle Network 2 introduces him as a copy of the original Bass (the player will also fight the true Bass in the WWW Area), whilst this form is fought twice in Battle Network 3 - once where he is completely unbeatable, and the other just before fighting Alpha. In Battle Network 4, the player must obtain six Soul Unisons, to open a door in UnderNet4 which will eventually lead to him. In Battle Network 5, Bass is encountered in a dead end in Oran Area 3 and Nebula Area 4(with Bass/Sol Cross MegaMan) after the Dark MegaMan Liberation Mission. In Battle Network 6, the player can jump into a pit behind a giant tree in Green2, which will lead them to UnderNet Zero, once there approach the gravestone, which is titled "Cyberworld's God of Destruction".


 * Bass α (Alpha): Only encountered in Mega Man Battle Network 5 Double Team DS, Mega Man Battle Network 5: Team Colonel and ProtoMan (if the player use the Bass Cross MegaMan E-Reader Card or cheat). All of Bass's attacks are more powerful and damaging.


 * Bass β (Beta): Only encountered in Mega Man Battle Network 5 Double Team DS, Mega Man Battle Network 5: Team ProtoMan and Colonel. All attacks from Bass are more powerful and damaging than his original and alpha forms. It is also named as "Chaos Lord", the form the Chaos Lords takes in.


 * Bass Ω (Omega)/SP: This is often Bass's ultimate form, randomly encountered after beating the original, in Mega Man Battle Network 4 and 5. These forms often sport about 3000 HP or 3500, along with a slew of highly damaging attacks. The SP form is fought in Battle Network 6, with 2700 HP instead, and slightly weaker than expected from the other forms. Defeating him in Mega Man Battle Network 6 will net the player a Bass F or BassAnly F Chip.
 * Mega Man Battle Network 3 Bass Omega has 3000HP, now actually shoots 6 (six) orange/golden-yellow energy shots, totally replacing the regular green Air Burst shots, has a 200 Life Aura (for an unknown reason, he could have the Dark Aura instead in this form), along with all the other attacks carried over from his GS form. It is his most powerful form, and is much more powerful than the previous forms of Bass.

Special Forms

 * Bass DX (DeluXe): Encountered only as a random encounter in Battle Network 2 after beating the true Bass, this form sports 2000 HP, a 150 Life Aura, and alternate charged forms of his Shooting Buster attack. They also inflict more damage than usual. He can now use his new move, the Earth Breaker attack, which inflicts a great amount of damage. This form is a very balanced final form.


 * Bass GS (GoSpel): Encountered only in Battle Network 3 near the BugFrag Trader, and only after the player has spent at least 300 BugFrags on it. Bass GS sports 2000 HP, a 200 Life Aura, and several new, highly powerful attacks, thanks to his synchronized fusion with Gospel. This form is focused more on offense, due to Gospel's powers.


 * Bass XX (Double X) Encountered only in Battle Network 4 and 5. These forms sport 4000 HP, a 200 barrier (BN4 regenerating but in BN5 it can be permanently removed if Northwind is used), and their attacks are exceedingly damaging. It is one of the most powerful forms in the Battle Network series. This form is extremely strong, but seems to adopt a speedier and more defense-like stance, unlike most final forms. This form is also a very balanced final form.


 * Bass BX (Beast eXpansion/eXtension): Encountered only in Battle Network 6, after defeating Bass SP in the Graveyard. This form sports 3400 HP, a series of exceedingly damaging attacks, and also a vast signature attack from the Cybeast of the opposite version. Bass BX is the most powerful form for any challenger in the entire Battle Network series. This form removes Bass's Life Aura entirely, but replaces it with extremely speedy and powerful, almost unavoidable attacks (His cape becomes the shield instead, repelling attacks unless he attacks). This form is best suited for quickly crushing an opponent and wearing them down. Defeating him in the Gregar version will give the player a Colonel Army chip and in Falzar a Hub Batch chip.

Abilities
Bass has tremendous potential that no other Navi ever had and is considered to be the strongest Navi in the MegaMan Battle Network games. He possesses plenty of attacks, abilities, and a constantly changing arsenal throughout the games. Bass is also by far MegaMan's strongest opponent, outranking even the final bosses by great power, and if not, by agility and defense (as mirroring the original Bass and Mega Man). In the anime, he is extremely powerful, however, he is not as powerful as his previous incarnation, PharaohMan, due to missing Ultimate Program.

General Abilities

 * Get Ability: This is Bass's most important and essential ability. Like the classic Bass, Bass can absorb the abilities of defeated foes. He used this to survives and gains every abilities of defeated foes, including Life Aura, Gospel, Alpha, Dark Soul and Cybeasts. In the anime, he has no such program as he merely feeds on any data program for the purpose of his missing Ultimate Program. It is assumed that because of this, Bass is able to consume any other types of power to refill his original strength. In Rockman EXE Stream movie, he utilized this ability in an attempt to absorb MegaMan's Ultimate Program to defeat Nebula Grey, though this backfired and created Forte Cross Rockman. Following Nebula Grey's defeat, it is implied that he absorbed its remains, gathering enough power to exact his revenge on Slur.EXE.


 * Giga Freeze: This ability is mentioned only in MMBN3. This attack isn't used in in-game battles. Bass obtained the Giga Freeze data by the Get Ability ability towards the end of MMBN3 storyline when MegaMan tried to use it to prevent the Cyberworld monster Alpha from rampaging. This was because he was one the only Navi besides MegaMan who could make contact with the program without being permanently frozen by it. Whether Bass still has this program and/or uses it, remains unknown.

Transformation Abilities
These are taken through the Get Ability program above.
 * Style Change: Bass used his Get Ability to copy MegaMan's Hub Style in MegaMan NT Warrior (manga). Just like MegaMan.EXE, Bass's strength, speed, and power greatly increase while using Hub Style.
 * Beast Out: In MegaMan NT Warrior (manga), Bass used his Get Ability to absorb Falzar and attained the power to Beast Out in order to fight MegaMan, who had already gained the ability to Beast Out from Gregar.

Offensive Abilities

 * Air Burst: This move was used only in MMBN1, 2, 3. Bass fires a green, speedy and powerful energy shot at the player.


 * Buster Rake A.K.A the Bass Buster, Shooting Busters, Bass Supreme Buster, Explosion, and Ω Buster
 * Variable Buster Rake: This move is used only in MMBN1, 2. Bass uses both of his busters to fire several green/orange/golden-yellow energy shot from his position to player's field, dealing a grand amount of damage. In MMBN2, he can only use these attacks when his health is low:
 * Red: Bass shoots up to 6 red shots with on different rows.
 * Blue: Bass shoots a blue burst that acts like a machine gun that hits any opponent's panel one at a time.


 * Gospel Power Exclusive to MMBN3:
 * Gospel Claw: If Bass gets hit too many times, he'll point player's current panel, and two of Gospel's claws will attack player's position from the air, cracking the panels they hit.
 * Gospel Breath: Bass first targets the player's field, then unleashes a one-panel Gospel Breath attack that spreads to the 6 panels in the back, inflicting great damage.
 * Vanishing World: A.K.A Banishing World. This attack is used only in MMBN3. Bass can only use this when his HP is 500 or less. Bass morphs his hand into a huge Gospel Cannon and then fires a very destructive white laser which destroys nearly all of player's panels, pierces through player's defenses, and inflicts heavy damage to player. However, while this attack is his strongest here, it can only be used once, unlike his other attacks. This move was also used in MegaMan NT Warrior Vol. 7 and was also Bass GS's finishing move.


 * Alpha Power:
 * Earth Breaker: A.K.A Earth Breaker Fist, Earth Impact. This move is used only in MMBN2 and 3. The aura protecting Bass will disappear when this move is used (but then again, Bass will fly out of reach or use the move very quickly). He will float on his side of the field, hitting his opponents by slamming his own hand to the ground with tremendous force. It also pierces defenses and breaks the column that the player's standing on. Bass is vulnerable for a split second after this attack lands.
 * Neo Buster Rake: This move is used only in MMBN4, 5 and 6, and is one of his more common attacks. Bass uses both of his busters to fire at player's field's random points at the same time. In MMBN 4 and 5, this attack will take out his Dark Aura (if available) for a moment, and a "barrier" is created before his hands before he shoots. In MMBN 6, the attack no longer induces temporary invincibility, resulting in undefended players taking multiple hits of 200 damage or so each. Accuracy and rate of fire increase as Bass's forms get stronger.


 * Dark Power Exclusive to MMBN4, 5, 6:
 * Hell's Rolling: Bass charges up, then shoots 2 to 4 cutting rings/wheels that can change its path to hit player, pausing at player when hit and inflict great damage. In MMBN6, instead of 4 rings/wheels, he now summons 2 rings/wheels simultaneously, which will converge at the player's position if player does not move soon enough.
 * Dark Arm Blade: This move is used only in MMBN4 and 5. Bass will appear next to player and swing his arm in a wide sword and/or long sword motion, often does multiple times in combination. In the anime, it is depicted as if Bass was clenching his fists with darkness shooting out from the top of his hands, similar to Zero's Recoil Rod.
 * Darkness Overload: This move is used only in MMBN4, and 5. He rushes onto the front center panel of the player's area, greatly damaging and cracking the back two columns with a large overloading sphere of darkness. If the player is standing on the same panel he is, they will still take obstacle damage.
 * Chaos Nightmare: Only in MMBN5. A midair version of Darkness Overload where Bass will float up, then creates a very devastating and overwhelming large overloading sphere of darkness in the air. He then targets player's current location before hurling it down on player, damaging and cracking a 3x3 area, piercing invisibility. It also inflicts quite a lot of damage.


 * Battle Chips: Exclusive to MMBN6. Bass is capable of using attacks similar to Battle Chips. Except Tank Cannon and Dark Sword, all other chip attacks aren't used by Bass BX and are able to dispel certain Crosses.
 * Tank Cannon: Null element. Crack last player's row if it misses.
 * Golem Hit: Break element. Bass can target it where player is standing, not just the front of player's area. Replaced his Earth Breaker.
 * Fire Burner: Fire element.
 * Dark Sword: Sword element. Acts like the similar Dark Chip. Replaced his Dark Arm Blade.


 * Cybeast Power Exclusive to MMBN6. These attacks inflicts great damage and penetrates player's defensive abilities such as invisibility.
 * Falzar Storm: Exclusive to Gregar's players. Bass uses the Cybeast Falzar's head to brew a powerful wind-based Falzar Storm. This attack also removes auras and barriers.
 * Gregar Breath: Exclusive to Falzar's players. Bass uses the Cybeast Gregar's head to unleash a powerful fire-based Gregar Breath.


 * Attacks used in Mega Man Network Transmission:
 * Spark Chaser: Bass fires a laser beam that moves at 90 degree angles, and can turn twice.
 * Homing Spark: Bass fires a slow-moving spark that home in on the enemy.
 * Delete Tower: Bass throws a pair of bombs to the ground that erupt into huge energy pillars.
 * Cross Burst: Bass throws sparks creating 4 beams in a cross pattern.

Defensive Abilities

 * Float: Bass always floating so changes in panels and attacks whenever he's moving never affect him. In MMBN6, he cannot cross over broken panels.


 * Aura: Bass's protection in MMBN 1-5:
 * Life Aura This ability is used only in MMBN1, 2, 3. A self-regenerating aura that Bass adopted. Its HP of 100-200(MAX). Only wind attacks or certain attacks equal/higher than the aura's HP can remove it, and Bass then regenerates the aura after using certain attacks. Causing him to flinch while he's executing the attacks may prevent him from regenerating the aura. He obtained this ability presumably by absorbing it from a piece of the Life Aura data of SciLab with his Get Ability ability.
 * Dark Aura: This ability is used only in MMBN 4, 5 by Bass XX. This aura acts like a Barrier 200, but with a self-regenerating ability. When the player uses a Northwind Chip; however, the barrier is dispelled and will not regenerate for the rest of the fight (except in MMBN4).


 * Cape Shield: Bass (excluding Bass XX form) doesn't have an aura or barrier of sorts in MMBN4, 5, 6. Instead, he uses his cape as a shield, which can block just about anything if he isn't attacking, with the exception of breaking attacks. In MegaMan NT Warrior (manga), Bass gains this ability by using his Get Ability to absorb Serenade.EXE.

Mega Man Network Transmission
(Megaman.EXE stumbles upon a secret area, which open entering, encounters Bass.EXE hovering in the air.)

Bass.EXE: You are nothing...

(Bass.EXE's cape billows in the air as he gives off an intense energy field.)

Bass.EXE: Little boy... How did you get in here...?

Lan Hikari: What!?

MegaMan.EXE: This surge... If I get any closer, it'll blow me away!

Lan Hikari: Grrr...! This is more than just a Navi! Careful, MegaMan!

Bass.EXE: ...? ...You...scum... You defeated Zero... Now, that's interesting. How powerful are you worms...?

Lan Hikari: He's attacking!? MegaMan. Battle routine! Set!

MegaMan.EXE: Execute!

(MegaMan.EXE and Bass.EXE engage battle. Because Bass.EXE is so powerful, he is invincible and cannot be harmed, so MegaMan.EXE has to endure the barrage of attacks until Bass stops.)

Bass.EXE: ...How did you withstand my attack... Now I know why Zero lost to you... Interesting... I think I'll actually try this time...

MegaMan.EXE: It's no good, Lan! He's too powerful!

Lan Hikari: Argh!

Bass.EXE: ...Nah... Not this time...

Lan Hikari: !?

Bass.EXE: It won't be long until judgment day... You'd better be ready...

Trivia

 * Bass is the only Navi with a missing Navi mark. Instead, a large scar is placed where the mark should be. The official Navi mark never appears in any game, but the manga and Rockman.EXE Official Complete Works depicts it as the "Forte" symbol, the musical term for "loud" or "strong."
 * In addition, Bass is also missing his violet eye streaks in the beginning, and later has them after receiving his scar. This may be a result of Bass absorbing many abilities (namely embedded with some sort of dark power from the Undernet) while plotting his revenge.


 * As part of the Rockman.EXE and Duel Masters crossover, Bass had a promotional card named "Forte, Brave Fear Lord" (勇騎恐皇フォルテ) in Duel Masters, and two Phoenixes appear in Mega Man Battle Network 5 as Giga Chips.


 * One of his official chips always summons a Buster Rake or Hell's Rolling, except in BN3, where he uses Earthbreaker for he did not have Hell's Rolling at the time. BN5 follows this tradition, but adds a variant where Bass summons Chaos Nightmare when the Giga Chip "Chaos Lord" is used.


 * There is also a Giga Chip 'Bass GS' (with an X symbol) that can only be gained from a Capcom promotional event for MMBN3 in Japan or through cheating. The chip involves Bass using the Vanishing World attack, inflicting 700 damage (but those standing in specific squares before the attack, standing right in front, or are invincible in specific manners are unaffected). This chip replaces the original Bass (White version) and Bass+ (Blue version) chips in the game when received (even if Bass GS is beaten before the promo event) and is also similar to the chip in the first BN game that also has been said to only be received through cheating, but like the traditional, Bass uses Air Burst/Buster Rake. The GS (X) Giga Chip can be stated to be Bass's strongest chip in the whole Battle Network series.


 * Bass is the first non-DS boss in the entire Battle Network Universe (including Star Force) to use chip attacks, the second being Acid Ace. (This does not count Area Grab, because it is too easily abused and often appears as a step in a Program Advance or a move unique to a Navi.)


 * The dark barrier which Bass created in front of him before shooting Buster Rake is very similar to Serenade's Holy Shock, only varies in color. This might be the proof that Bass has defeated Serenade.


 * In Mega Man Battle Network 2, a Bass copy makes a reference to his Japanese name with the line, "Battle is my forte!" Which is never said on the original Japanese dialogue, where he simply states, "...Understood... You can leave the fighting to me!"


 * Bass in MMBN2 (or rather, his copy) started the tradition of the double final boss battle. This tradition was also in Battle Networks 3 (where the real Bass was the first boss) and 4. A similar battle is also in MegaMan Star Force 3.


 * A dark silhouette of Bass appears on the "Dream Aura" Giga-Class Card of Mega Man Star Force.


 * According to a side story Ryo Takamisaki's manga, Bass's first ability absorbed via the Get Ability program was a Heat Blade, which he took from a bitter Elite Corps Navi who had stayed behind in order to delete Bass after his orders to do so had been changed to focus on the Alpha program.


 * While Bass.EXE's personality is pretty similar to that of the original Bass, the original Bass does not hate humans, he has some degree of respect for humans, since they were the ones that created robots.


 * UDON's English translation of Rockman.EXE Official Complete Works stated that a rule was made in which Navis could not have any cloth in their designs. Yuji Ishihara, the character designer for the Battle Network games, confessed to breaking this rule upon designing Bass, for he wanted to give him his trademark cape because of the Navi's tragic past.


 * In Mega Man Battle Network 2, a Program Advance involving Bass and Gospel can inflict of upwards to 6000 damage in which Gospel attacks with its breath, then if the enemy is still alive, Bass uses Earth Crusher that inflicts another 3000 damage. However, one of the chips required cannot be obtained normally without a Japanese exclusive event or a cheating device. This Program Advance is easily the most powerful in the entire Battle Network series, although it makes an appearance in Mega Man Battle Network 6 as a greatly watered-down version. The only possible way to get a higher damage is with Meteor in the second game, which can be done by areagrabbing three times (and the enemy locked into one panel), changing the stage to Grass and using Meteor with 4 Fire+40 chips for a total of 6200.
 * Curiously, Bass is the only being in Mega Man Battle Network - NetNavi or otherwise - that outright copies abilities, rather than using Battle Chips to perform the abilities of other Navis and viruses as MegaMan does.
