In ''Legion of Super-Heroes'' vol. 5, #1, Cosmic Boy is the leader of the Legion of Super-Heroes. After seemingly destroying the [[Dominators (DC Comics)|Dominators]]' homeworld (he actually sends it to the [[Phantom Zone]]), Cosmic Boy is voted out of office, being replaced by [[Supergirl (Kara Zor-El)|Supergirl]]. He then joins a superhero team from the 41st century, who come back in time to offer him membership.
