I loved the Alan Moore written version. Just a great take on the old Superman mythos.
Great blend of Martian Manhunter and Superman with something new. Deserves more exposure.
Interesting re-take on Superman if he had been around since the golden age of Greek culture and was a breed warlord.
Superman's little brother... sort of...
The other alien survivor on Earth.
Interesting knockoff with possibilities never reached.
The High (original version)
Truly if Superman was a total bastard.
Apollo (original version)
Gay Superman was a cool Superman. I liked the fact that he was a nice guy that could rip your head off.
I liked that they ultimately made him an Eternal or at the least, long suggested it.
Hyperion (Supreme Power)
Victor taken to that possiblity.
Superman being an Imperial... Super Stormtrooper.. LoSH style.. via Marvel.
The insane moron Superman. Pure chaos waiting to happen.
I don't think of Captain Marvel or similar characters like Marvel Man/Miracle Man and Mighty Man as Superman knockoffs. The others are more similar to Superman, IMO, then not.
