Suggested by iKnowledge Isidro is back, but his match against Superboy won’t turn out all that much better for him than the last round. Superboy is very powerful and at his absolute best he is able to give Superman a decent fight. Isidro isn’t nearly old enough to have the physical abilities needed to win this match. I don’t doubt that he could probably pull off some kind of comeback once there is a big time skip, but at the moment that’s just not something that he can hope to achieve. Superboy may as well be in a different world in terms of power. Superboy wins.
