Trivia: Sonic The Hedgehog Mega Man Worlds Collide
Creator Breakdown: A literal example, for according to this, Jamal Peppers, who drew parts one through three and most of four, was hospitalized before he could finish the last few pages of part four. Ryan Jampole stepped in to finish the pages for him so things could go according to plan.
Name's the Same: The Roboticized Master, Shadow Man, and the actual Shadow Man from the Mega Man franchise. Lampshaded in Part 6, where Eggman announces he'll sent Shadow Man to intercept the heroes, Wily asks which one. After a Beat Panel, they agree to send both. Then, in Part 7, when faced with them both, Sonic has trouble giving directions to Mega Man about who to attack.
An example involving another occurs later on in part five with there being now two green Sega robot characters named Vector Man. Also lampshaded in Part 6, where the character's name reminds Sonic of a trash collector, which was the job of the original Vectorman.
