Ooohh interesting, he would switch to certain fights from those universes

Swapping to bromalgamate battle, then Underswap papyrus, underfell undyne, gaster blaster sans, and maybe some more

After he's done with that, he realizes his efforts are useless. Until he says he has to do one last experiment.

He uses determination on himself, and becomes Corrupted Gaster.

That is a cool idea.
