It's scary how there is some similarity between the two?
Both are two warped versions of Superman Both appear every six months. Both have annoying quirks. Henshaw always wants a damn War World. Prime wants his perfect Earth. Though one got what they wanted (Prime), the other did not until Sinestro Corps War and was like, "Eh I got better things to do." However where Prime is a more unstoppable force while Henshaw is just unkillable.
