Mr Majestic vs Gladiator
Battle of the Pre-Crisis Superman clones.
Gladiator: Scion of the Shiar. He is the strongest defender of the Shiar empire, leader of the Praetorian guard. He has flown through the heart of stars, fought might foes, and is a one man engine of destruction. Invulnerable, able to move so fast he can achieve hyperspace, and can even shoot beams of energy from his eyes, super-senses. He also has the ability to resist attacks on his mind for quite some time. He is Marvel's answer to Pre-Crisis Superman, and unlike Kal-El Gladiator is a cunning warrior who uses his mind just as much as his brawn. His only weaknesses are radiation, and the fact that he gets weak if he loses faith in himself.
Mr Majestic: Kherubim warlord. He is an immortal lord of the Kherubim, alive for millenia. Willing to do whatever it takes (including killing his own teammates when he knew letting them live would lead to doom) he is exceedingly cool and calculating (like Gladiator, and unlike Superman, he uses his mind as much as his brawn). Mr Majestic has moved the entire solar system, all 9 planets, in order to save them from a planet consuming entity. He has split stars into two, and can fly from galaxy to galaxy just for the heck of it. Having strength at Pre-Crisis levels, he also has the added benefits of Kherubim warrior training, energy beams from his eyes, super-senses, and hyper speed. Furthermore he has a psionic shield that protects his mind from (just like Gladiator) psionic attacks. But he has also has limited telepathic abilities. He is Image's answer to PRe-Crisis Superman (Image was later acquired by WildStorm, which went to DC - where Mr Majestic popped up for a Crossover and whipped their heroes). His weaknesses are that he can become too cold emotionally, seeing friends as foes if it serves the greater good.
This battle is set in an abandoned solar system far from our own (both characters can survive in space, so the vacuum of space is of no ill effect). The characters are told to let it all lose. If Gladiator loses then the Shiar empire is destroyed, and Gladiator would never let that happen. If Mr Majestic loses then the Daemonites (who have been waging war against the Kherubim for millenia) win, and Khera and its billions are slaughtered. None will give an inch. Both are at Pre-Crisis Superman levels. Both are calculating warrior lords.
Who wins?
