I've been thinking should I let him travel to different dimensions.

If so then it won’t  be crazy just one every little while there will be no specified time or place. ( By dimensions I mean other animes he got powers from like Dragon ball or the video games like prototype )

If not then he will stay in the nations and never visit other worlds.

It's up to you.

Edit: I've thougth about it and I have Decided that I will no longer ask you to vote unless its for the world or a new character sence this is a story changing thing sorry chapter is no longer needed.
