FYI, Undertale spoilers >o<

Now let's see.....

Apocalypse from X-Men would use Black Knights cuz 4 of them are themed after the Four Horsemen of the Apocalypse.

Junko Ekoshima from Daganronpa would use a Thunder Mine HD deck considering how it's play style punishes the opponent if he/she tries to do anything he/she would be punished.
