Always game for a crossover! Couple questions in regards to characters:

Are duos accepted for a single slot? Something like Jak & Daxter, Sherlock & Watson, Rick & Morty - a pair of characters most notably seen together like that?

When it comes to villains, how much leeway would we be given in our villainry? I have an idea for a villain character but his main shtick is largely turning ordinary people into little supervillains of their own and bossing them around, not that he doesn't / can't do stuff himself.
