Studios released a six-issue miniseries based on Mega Man: Fully Charged in August 2020, which has made the return of the Archie comic even more unlikely.

[2] As in the Mega Man games, the comic is set on the planet Earth in the year 20XX, a not-so-distant future period in which advanced robots capable of independent thought and decisions making have been developed.

The evil scientist Dr. Wily sets out to conquer the world, doing so first by stealing or creating advanced automatons known as Robot Masters.

In order to stop him, Rock -- a helper robot created by Wily's old colleague, Dr. Light -- volunteers to be equipped with weapons so that he can stand against him.

In addition to the casts of the main Mega Man and Sonic books, Worlds Unite also features characters from the Mega Man X and Sonic Boom universes, as well as several other Capcom and Sega franchises such as Street Fighter, Golden Axe, Viewtiful Joe, Panzer Dragoon, Ōkami, Nights into Dreams..., Monster Hunter, Ghosts 'n Goblins, and Skies of Arcadia.

Both of these stories included buildup to the events of Mega Man 4 and set up for subsequent games, enabled by Wily's association with the X Corporation and his deception of Blues.
