Superboy Prime is the most powerful being on the DC universe, even stronger than superman since he doesn’t share his vulnerability to kryptonite. Took the whole JLA, JSA, Green Lantern Corps, and others to defeat him.
They couldn’t do it, so they just trapped him inside a sun, which would later turn out to be a very stupid idea.
