Duo is a robot descending from outer space in the Year 20XX in another zone. An ally of Mega Man, his prime objective is to seek out and destroy evil. He aided the heroes in battling Dr. Wily and Dr. Eggman when both his universe and Mobius Prime were reset by the second Genesis Wave.


Distress Call and Aiding the Heroes

Duo Receives Transmission

Duo receives Dr. Light's transmission.

Realizing the danger threatening his world following the second Genesis Wave, Dr. Light sent a distress signal to Duo, who was meditating in orbit around Saturn. Duo immediately began traveling towards Earth, making his landing in Light Labs. Sensing the presence of evil, Duo was quickly transported by Roll and Auto to the Skull Egg Zone, where he met Dr. Light outside the Wily Egg. Entering the flying fortress, Duo found Mega Man and Sonic the Hedgehog battling the Chaos Devil, and quickly took over for them in order to rid the creature of its evil. He also informed the two heroes of the Skull Egg Zone's parasitic effect on their respective realities.

The resulting battle threatened to tear the Wily Egg apart, but Duo eventually succeeded in splitting the creature back into Chaos and the Devil Core, crushing the latter and looking on with the former as the doctors' Super Genesis Wave began to rewrite reality. Following the defeat of Doctors Wily and Eggman, Super Mega Man used Chaos Control to return his reality back to normal, leaving Duo's fate questionable, as he had yet to land on Earth in this restored reality and initially came from a rewritten world thanks to the second Genesis Wave.

Duo is a powerful but noble being, determined to see justice done and evil destroyed. Having formed a bond with Dr. Light and Mega Man, he was quick to respond to the doctor's call for assistance.


Duo is immensely powerful, capable of independent flight and receiving communications from across vast distances. He also has the ability to sense evil forces, whether in environments or individuals. Energy manipulation also appears to be a talent of his, as he can employ it against enemies or use it to impart his own strength to others, be they living or artificial beings.

Background Information

  • At the time of the "Worlds Collide" crossover, Duo had not yet made his official debut in the Archie Mega Man comic series. In game canon, Duo first appeared in Mega Man 8, a game which had not yet been adapted by the comic when the crossover began. The fact that the Genesis Wave fast forwarded Mega Man's universe into the future is what allows Duo to appear early.
    • Duo is one of several Mega Man characters in which their debut in the crossover is also their debut in the overall Archie Mega Man continuity. Interestingly, his first issue was not an issue of Mega Man, but an issue of the Sonic Universe series.
