Not sure, since I only read the summary. However, Superboy practically had no weaknesses before that anyways (Magic barely affected him and red suns don't affect him at all.) Then again, maybe it was that he was no longer affected by Kryptonite, because I think I remember there being something in Infinite Crisis about his Krypton never exploding to begin with, thus no Kryptonite to affect him.
...Oh, yeah, thought I should probably mention this is Superboy Prime, not the Superboy from the Teen Titans.
