Sonic Universe - Worlds Collide

Issues #51–54 were included in Archie's 'Worlds Collide' story arc, a twelve-issue event featuring a crossover between the Sonic the Hedgehog and Mega Man comic series produced by the company. These issues, rather than being chronologically back to back, were instead released in sequence with the Mega Man and Sonic the Hedgehog issues, serving as parts 2, 5, 8, and 11 of twelve.
