Is it possible for him to got new worlds for like 2-3 chapter before he gets too strong because when characters go to other worlds with a lot of strength they tend be lazy and really laid back and anything they get is never really important and at most broadens they’re versatility, like right now him going to a world like marvel or dc would be more stressful for him than it would by the time canon arrives unless he enters during a time period where a character has an explosive level of power for the moment like fully unleashed dark phoenix or combined sentry or Dr manhattan or a super charged dark superman
