Battle takes place Pre-Flashpoint, DC new Earth.
Imperiex prime arrives in DC new Earth universe with the intention of blowing it up. When he arrives he finds that Monarch had already taken over that Universe, and destroyed all the heroes that would be defending it. When he travels to Oa he finds its a barren husk and Monarch proudly hovering above the dead planet. The two spot each other form 5 miles apart and immediately attack one another.
Both are the most powerful incarnations of one another. Battle is one vs one, no probes, no army and no interference. Winner will be determined by any means necessary. Who would win this battle of two immensely powerful beings that both contain the power of the "Big Bang" inside of them and why?
All comments are welcome.
