Those are toons though.

Are you suggesting that if Popeye left his universe he'd loose his toonforce?

Look at it this way. Goku can use ki. So can almost every major character in Dragon Ball Z. But if they left they universe, they wouldn't loose their ki, and someone who entered the universe wouldn't instantly gain it.

It's a matter of origin and upbringing, not presence.
