Thought on cross over characters?

Random popular anime characters for images. All fighting games these days have cross over characters or quests, and sparking zero has an interesting DP system where they can bring in weak characters on the system. But in the interest in Fandom arguments and power scalers I think it's perfectly reasonable to keep all guest characters at either 4DP or 5DP which is normal.

The explanation in game for them would be "additional universes for the TOP." not that it would really matter honestly. You think that would ever pass?
