Crossover Combo Villain

Go To
Were you expecting a unique boss? TOO BAD, BWALUIGI TIME!

When one creates a crossover, the issue of who the villain of the event should be comes up. Should it be a villain from one of the involved properties, a team-up, or something new altogether?

Sometimes, the best solution is to combine stuff from the crossing over universes to make a villain appropriate to both. Thus, the Crossover Combo Villain. It could be a character from one work utilizing an element from the other, a literal fusion of characters to create a single new antagonist, or something else entirely— so long as it combines elements from the involved works into a single antagonist, it qualifies.

Note that just having an original villain for a crossover doesn't count, they have to combine elements from the works crossing over in some way.

Contrast Crossover Villain-in-Chief, which sees an already established villain rise to lead the forces of evil.
