10 Teen Titans Who Could Beat Superman
7. Kid Eternity
Kid Eternity, the Master of History, has all sorts of vaguely defined powers including transdimensional teleportation, telepathy, precognition, the ability (I'm not making this up.) to turn his body into brain waves and inhabit another person's mind, and his most iconic power; the ability to summon or transform into any dead person, temporarily, by saying the magic word; "Eternity."
He's called on heroes, villains, and gods in the past, and there are plenty of dead gods for him to summon now, including Drogue, the sea god who effortlessly stomped Superman during the Drowned Earth arc.
If Kid called on him, or the other gods at his disposal, Clark would be no match for him. He could also just possess Superman, since that's another one of his powers. Or he could teleport Supes to Hell, and leave him there. He has plenty of options.
