Name a character that has been proclaimed "the most powerful being in the universe" within that character's respective universe. [i]Note: Exchange "universe" for "world" or "galaxy" if necessary.[/i] For example, in [b]Kirby Super Star Ultra[/b], Meta Knight summons Nova and wishes to fight the most powerful warrior in the galaxy - that being Galacta Knight. We will be ignoring the main protagonist of any game, show or book (series). So characters like Goku wouldn't count.
