A recurring boss character in the [i][[kirby_(series)|Kirby]][/i] series. He makes his debut in [i][[Kirby Super Star Ultra]][/i] at the very end of the [i]Meta Knightmare Ultra[/i] subgame, where [[Meta Knight]] summons [[Galactic Nova]] to wish for a fight against him. Since then, he has made various re-appearances as a secret superboss in future [i]Kirby[/i] games ([spoiler][[Kirby's Return to Dream Land]] and [[Kirby: Planet Robobot]][/spoiler] to be exact)

He is the strongest warrior in the galaxy in Kirby's world and was sealed away because he was deemed too strong [spoiler]([[Star Dream]] even suggests that he may have destroyed at least one planet in the past)[/spoiler].

[spoiler]He also appears in [i][[Super Kirby Clash]][/i] as a true final boss, surprisingly enough. Here, he is dubbed "Aeon Hero" and is implied to be one of the ancient heroes who sealed away [[Void Termina]] long ago.[/spoiler]
