Enker

Enker is a Robot Master and the leader of the Mega Man Killers created by Dr. Wily in the Sonic the Hedgehog and Mega Man comic crossover event, Worlds Collide. Created to destroy Mega Man, he and the rest of the Mega Man Killers–Ballade and Punk–were revived after the Genesis Wave reset both Mobius and Mega Man's world.

Enker posses a long staff, one similar to the one owned by Buster Rod G, only if Enker's staff is moved at high-speed, he can perform his Master Weapon, which is the Mirror Buster.

History
At some point in the rewritten reality of the Earth in the year 20XX, created due to the Genesis Wave, the Mega Man Killers were utterly destroyed by Mega Man. However, by using the time-space altering properties of the Genesis Wave, Dr. Eggman and Dr. Wily were able to revive the Mega Man Killers. (WC #1, #10)

Upon Mega Man, Sonic the Hedgehog, Miles "Tails" Prower, and Rush accessing the Wily Egg and entering inside, Sonic and Mega Man were telling each other about the Wily Egg reminds them more of there respective final-zone areas. Suddenly, Sonic notices guards blocking their way, and Mega Man recognizes the guards as the Mega Man Killers. The heroes then begin the fight the Mega Man Killers, as Sonic took on Punk; Tails and Rush fought against Enker; and Mega Man took care of Ballade. Mega Man tries to make Ballade hesitate and remember the Robot Master's sacrifice on him (from Mega Man IV), but Ballade has no connection to those memories. Mega Man then remembers that the Skull Egg Zone can mess with the time-space control, and the two continue to fight. Sonic is able to make Punk accidentally destroy Enker via from Punk's Screw Crusher. Whether Enker or the rest of the Mega Man Killers will return to the crossover is unknown at this time. (WC #10)

Weapons
The Mirror Buster is Enker's Master Weapon and offense move that appears in Mega Man #27. With this move, Enker can spin his staff into circles multiple times to cause a barrier for him. This makes any projectile coming towards the Robot Master impossible to reach him, as Enker moves the staff so fast it makes a barrier in front of him. However, Enker had fought Tails and Rush with this Master Weapon, but he had failed via Punk's Screw Crusher destroying the Robot Master. (WC #10)
