Wily Machine 1

Wily Machine 1 (ワイリーマシン1号) is the first Wily Machine created by Dr. Wily. It is the final boss of first Mega Man game, appearing in the final stage of Dr. Wily's Robot Manufacturing Plant.

Mega Man
The weak point of the Wily Machine's first form is the red gun. Mega Man must destroy the red gun using Fire Storm or the Mega Buster. Once the gun is destroyed, Wily appears in the cockpit, and the remaining hole shoots spiraling large balls of energy. The second form has no specific weakness, but Thunder Beam can hit it twice with one beam. Another, albeit risky, method is to use the Rolling Cutter, which can hit it three times if timed correctly. A good strategy is to switch between weapons. Use Rolling Cutter when he is flying backward, and use Thunder Beam when he is going backwards.

Mega Man Powered Up
The Wily Machine Number 1 in Mega Man Powered Up is, at first glance, vastly different from the Wily Machine of the first game. However it's truly just a slightly modified version of the original clipped on to a base, and thus giving it its uniquely designed first form. The first form is a skull tank that roams horizontally along the ground, and its attack varies according to the mode/difficulty: on Easy and Old Style, it constantly fires small, energy shots, but on Normal and Hard, it starts to use all of the Special Weapons from the eight Robot Masters (although the Wily Machine will never use Time Slow on Hard). The top of the machine changes colors to match which weapon he is using, so it is recommended to pay attention to it during the battle to more easily counter his moves. When using Super Arm, the Wily Machine won't attack, and when using the Fire Storm, it will only attack when the player uses an attack.

The Wily Machine's weakness in Normal and Hard corresponds to the owner of its equipped Special Weapon (e.g. If the machine uses Fire Storm, its weakness would be Ice Slasher. The Time Slow does not stun the Wily Machine while it uses Super Arm, only Time Man's clock hand projectiles can accomplish this). Like most Wily Machines, it is only vulnerable in the cockpit. In all three difficulties of New Style, Mega Man C's Charge Shots, Proto Man's Proto Strike, Mega's Mega Kick and Roll's Roll Swing can stun the Wily Machine during this phase regardless of the Wily Machine's currently equipped weapon. On Easy, Wily will take off as soon as this form is beaten, causing the fight and game to be over.

The second form can only be fought on Normal, Hard or Old Style. After the first form has fallen to pieces, Wily gets up and starts to tinker with the machine (whilst the player's character stands there and watches him do it). The repaired Wily Machine, which now looks extremely similar to the second form of the Wily Machine from the first game, rises from the rubble and starts flying. In Normal, Wily will hover up and down, while on Hard and Old Style, then he will drift back and forth. Note that in this form, if Dr. Wily uses Super Arm, he can sometimes decide to throw the hammer he was using to repair his ship. This new flying form still uses all the Special Weapons, but it gains a new move that differs on the player's character:


 * When playing as Mega Man, Mega Man S, or Mega Man C in New Style, the Wily Machine temporarily gains two mechanical arms with spike tips and rushes forward. The easiest way to dodge it is to attack with its weakness before it rushes forward, causing it to be shocked out of the move (it should be noted that the Wily Machine will never be on Rolling Cutter or Super Arm when performing this attack, as it cannot be hit with their owner's weaknesses, the Super Arm or Time Man's clock hands, respectively).
 * When playing as any other character or in Old Style, it will fire charged swirling balls of energy, similar to the attack which the original Wily Machine also uses. In New Style, the player can stun the Wily Machine if they attack it with a weapon that it is weak against while charging the attack to prevent the shot from being fired.

Wily Machine 1 is the secret boss from World 3 in Rockman ×over.

Mega Man (Archie Comics)
After the Copy Robot is destroyed by the Robot Masters in issue 4, Dr. Wily appears in the room inside his first Wily Machine and starts shooting Mega Man. While attacking, Wily mocks Mega Man saying that he is just a helper robot, a lackey he had not stolen with the Robot Masters due to not being worth the effort and that should save himself from further embarrassment. While Wily is talking, Mega Man uses the Magnet Beam to go above the Wily Machine and jumps on the cockpit, punching it with the Super Arm.

Mega Man continues attacking with other Special Weapons while saying he is not embarrassed as he has a creator and sister who cares for him, while Wily had to steal his creator's robots to get attention, and even though he reprogrammed them, they could not stop a "lackey" like him. He asks Dr. Wily which one of them should be embarrassed and attacks with Fire Storm, opening the cockpit and revealing Dr. Wily inside. When Mega Man tries to use Fire Storm again, he can't attack due to being out of ammo. Wily laughs of him as he can't attack and he is still able to fly, saying he won by default, but Mega Man jumps on the Wily Machine and takes it down with a charge shot. With Wily defeated, Mega Man takes him out of the wreckage and sends him to the authorities.

When Mega Man returns to Wily's fortress in the story arc Time Keeps Slipping, the remains of the Wily Machine can be seen in one panel from issue 6 and issue 7.

Rockman (manga)
After passing by many dangers inside Wily's fortress, Mega Man finds Dr. Wily piloting the Wily Machine. Despite its menacing appearance, Mega Man manages to take it down with two attacks, the first opening the cockpit and the second blowing the machine. After the battle, Mega Man talks with the injured Dr. Wily and leaves the fortress.

Mega Man: Upon a Star
In the third episode of the OVA, Dr. Wily uses a vehicle similar to the Wily Machine 1 named Skullker (スカルカー) to leave the video game world.

Trivia

 * Interestingly enough, this Wily Machine is one of the few to serve as the final boss on the Mega Man series. Other Wily Machines serve as penultimate bosses instead, with the final bosses being (in order of game appearance) the Alien, Gamma and, finally, settling with the Wily Capsules.
 * Unused dialogue in Mega Man: Powered Up suggest that the player would be able to attack Dr. Wily while he repairs the Wily Machine Number 1.
 * This is one of only two WMs that visibly incorporates Wily's "Flying Saucer" vehicle into its design, with the other being the Wily Machine 2 from the second game.
