Being an accomplice is an interesting character hook. And not just for villainous exploits either. Imagine a game where the PCs are all sidekicks of major superheroes - a group of PCs playing Jimmy Olsen, Bucky Barnes, and Robin. The heroes go off and do something, leaving the sidekicks behind when some secondary crisis erupts. Or perhaps the major heroes even get into trouble which is over their heads, and the sidekicks have to come to the rescue.
