Worlds Collide

Worlds Collide, originally known by the much longer title Sonic & Mega Man: When Worlds Collide, is a 12-part crossover storyline between the franchises Mega Man and Sonic the Hedgehog announced on the San Diego Comic-Con International on July 10, 2012, published by Archie Comics' Mega Man, Sonic the Hedgehog and Sonic Universe comic books in 2013.

The event apparently takes place in the future in Mega Man's timeline as the main comic was only up to the events of Super Adventure Rockman at the time, while Worlds Collide features Bass, Beat, and Tango, and references Duo and Nitro Man. In addition, Mega Man also expressed confusion about the Genesis Unit's presence, as he had completely destroyed them from what was implied to be a long time beforehand. The explanation for this is that Wily used the Genesis Wave, a power with the ability to alter reality, to cause a time-skip.
