Dark Chip

Dark Chips are vastly powerful Battle Chips that increase a NetNavi's power beyond limits, but destroy its connection with its NetOp and turn the Navi into a Darkloid. Darkloids use these chips to survive. They start out using them to become more powerful, but soon become addicted and need them. After a while of addiction it starts to corrupt their data, until eventually they become so corrupted that they are deleted. In the anime Dr. Hikari says that the Dark Chips are a type of chip which trades a Navi's soul for power. They were created by Dr. Regal.

In the games, Dark Chips have several effects: First, when any number of Dark Chips have been used in battle, the user permanently loses 1 HP from their maximum HP count. Also, using a Dark Chip would result in a bug occurring on MegaMan, depending on the Dark Chip used (though most have the tendency to cause an HP bug). Finally, when MegaMan has used enough Dark Chips, he turns "dark" becoming the entity which is known as DarkMega or MegaMan DS, losing the ability to enter Full Synchro or to use Double Souls, and gains the ability to use chips exclusive only to "dark" MegaMan (like Snake or Muramasa), DS chips, and also will enter a "berserker" state on a lethal hit. To reverse the effects of "darkness", one must enter battles without usage of Dark Chips, and this process can be sped up by the "Soul Cleanser" NCP.

In MMBN4, Dark Chips can only be used when MegaMan enters an "anxious" state, after taking several hits in succession without fighting back. They take up the last 2 slots of the Custom Screen, and cannot be used with any other chip, aside from another Dark Chip. When one is "dark" enough, he can enter the battle with Dark Chips already displaying. In MMBN5, the Dark Chips are Battle Chips on their own, with their own code. Each folder can hold up to 3 Dark Chips at one time.

In both games, Dark Chips are the most powerful and overpowered chips in the game, but the glitches they cause can discourage players from using some of them (Chaos Unison bypasses the glitch, but with a twist besides, so it is is also rather ineffective, unless the player needs to reuse a Soul Unison, as the same Chaos Unison and Soul Unison can be used in the same battle).

In the anime, the chips simply power up whatever NetNavi uses them (but it is later shown there are still dark versions of chips like Dark Sword and Dark Cannon), but they still turn them evil. Another side effect, likely created to coincide with the fact that permanently remove HP in the game, is that they over time delete the data of whatever NetNavi uses them. The Dark Chips were also exceedingly addictive. ProtoMan.EXE turned evil in episode 27 of Axess after Chaud slotted in an extra strong Dark Chip to fight ShadeMan.EXE, though later a cure was found for it.

Dark Chips can be strongly compared to drug addiction in both games and anime in many ways. Interestingly, MegaMan can control DarkChip influence if used, but an overload of dark energy like a Dark Chip implant or a direct infusion of dark energy will cause him to turn into MegaMan DS, who also cannot die of Dark Chips, due to the fact he was born of pure dark energy.

There are 4 ways to obtain Dark Chips: 1) Enter the "Worried" or "Dark" state. (MMBN4) 2) Buy them from people who say the have "a really rare/powerful/alternate-colored chip" (BN5) 3) Use the Number Lotto. (Certain types only in BN5) 4) Find them in Certain Mystery Data. (BN5)

Additionaly, there are chips that can be only used while "dark". These chips are normally tagged with "Evil Chip!" in the description, and are normally powered up versions of their predecessors. Most are Mega Chips, preventing a player from completley building a folder around these chips.

List of Evil Chips
Under construction


 * EleDark/Element Dark: Like the other Ele-chips, when standing on the right type of panel (in this case a poison/swamp panel), the chip will be powered up, dealing more damage. Deals 240 base damage.


 * DrkLine/Dark Line: On the current row you are on, this turns the whole line of 6 panels into darkholes.


 * Muramasa: Like it's predecessors from previous games this chip attacks with a longsword chip which deals damage equal to the HP that you have lost.


 * Static: Like the Tornado chips, this creates a purple tornado 2 panels ahead for 8 hits of 20 damage. It appears to power-up to attack the two panels in front of you if you have a bug.


 * Anubis: Drops an Anubis statue onto the panel in front of you which poisons enemy's HP.


 * Hole: Creates a darkhole panel in front of you.


 * BugCharg/Bug Charge: MegaMan takes out the Gospel cannon then fires bolts down the row causing 200 damage times the number of bugs you currently have affecting you. Also removes bugs from you, acting also as a Bug Fix battle chip.


 * Blackwing: Pauses the screen then causes Batcaves to open up on the top outside of the enemies area which spew out a number of bats onto the enemies area. Using Area steals effectively increases the number of hits each column will take. Deals 20 damage per bat. (Note: that this chip is a direct copy of the attack which the Darkman chips on MMBN3 uses)


 * Any DS-level Navi chip.

Trivia

 * Intense hacking in Battle Network 6 will reveal that Dark Chips were planned to be used (and this time, didn't remove HP or cause a Dark State, but inflicting an extremely fast HP bug), but the ideas seemed to have been scrapped, seeing as there are no descriptions for some chips and no icons for any Dark Chip in that game. However, the chips work fluidly and don't freeze the game.  Also, Dark Sword and Dark Thunder made a return as BugRSword (Bug Rise Sword) and BugRThunder (Bug Rise Thunder), which when used, replace MegaMan's Charge Shot at the cost of sacrificing bugs (both are Giga Chips).  However, in Japan, one can use toy Dark Chips with the BN6 Beast Link Gate to download Dark Chips, inflicting the above bugs.  This does not apply to MMBN5 normal Battle Chips, but you can slot in chips from the opposite version of BN6.
 * In the anime, after Chaud gave ProtoMan a Dark Chip, he mentions Lan should have used it on MegaMan.  This makes sense (in a way anybody would have never imagined), as MegaMan would have only turned into MegaMan DS and remained loyal to Lan, instead of Chaud losing ProtoMan. Additionally, Chaud even knocked the chip out of Lan's hand.
 * Chaud actually went against his own advice not to use a Dark Chip in BN4 when he slotted one in.
