Alan Scott Vs. Superboy Prime

Vs.

Rules

Morals off, Superboy prime literally kills him.

SBP I think

The usual SBP? Because the usual SBP kills him to death so hard he disappears from old pictures like Marty McFly's brother.

The picture you're using though, is from SBP's one low showing.

SBP has a great track record against lanterns

SBP stomp an entire Lantern Core the Justice league two other Superman’s I believe also Titans as well and more at the same time So he gets bored with the fight and breaks reality again to come back and face Dr Manhattan

Superboy Prime wins easily.
