Here's what I've got. Let me know if it passes muster; it's pretty well a rip-off of a rip-off. The idea is more of a Superman that focused purely on the Super, and discarded the Man almost entirely. He knows he's the Other, and he's tried to be otherwise. And because he's not one of them, he doesn't feel particularly inclined to follow their rules. He's a Superman Lex Luthor could understand - he uses his powers to the fullest and as he chooses, and he doesn't rule the world because he's so powerful he considers ruling a bunch of hairless apes beneath him.
Name: Nobiliar of House Kell, alias Noble
Race: Kheran Lord
Description: Noble is a very tall, very muscle male. His skin is fair, and without blemishes or scars. His eyes are a very pale blue, while his hair is a fair blond shade. The male's hair is short enough for what is usually described as business casual. His mass and size are sufficient that he cannot pass himself off as a human being, and he would not wish to. Noble stands 6'10" tall, but his incredibly dense physiology results in a weight of 615 lbs.
His costume is a full body suit, in red, that covers all but his hair, face, and ears. The suit has a pair of metallic red pauldrons to which a cape is attached, and small compartments contain a handful of useful devices.
Bio: Nobiliar of House Kell is one of the Kherubim, a race of aliens divided into genetic heterogenous castes. The Lord caste was one of the most physically and politically puissant castes, possessed of inborn powers that excelled those of the others. Nobiliar's forebears used these powers to ensconce themselves within the government of the Kheran people, ensuring that their descendents would by default receive positions of power and influence. The Kherans were also a fervently expansionist people, engaging in warfare to keep their society focused outward in order to stave off decline and decadence. For the most part, the various castes of Kherans were easily able to defeat and subjugate those they faced.
Upon one planet, the Kherans encountered a race that would be called Daemonites, who possessed the ability to possess the bodies of other species and control them. The might of the Kherans were turned against them, and for once, the mighty Kherans faced an enemy that was not only able to pose a significant challenge, but sent them reeling back in defeat. The Daemonites forged themselves into a super-power with the knowledge they stole.
The war raged across worlds, and entire star systems were lost to it. Nobiliar fought in it. For decades, then centuries, and millenia. He was the second to Lord Majestros, who would eventually become the supreme commander of all Kheran forces in the Milky Way. The fate of the war culminated in a grand battle on Earth, and Lord Majestros made the supreme sacrifice to eliminate the Daemonite High Command. His dying order was that Nobiliar protect Earth as though it were his own home, and the younger Kheran complied.
Even devoid of intergalactic war, Nobiliar found Earth had problems all of its own. Its population held metahumans, both virtuous and malignant, and the planet itself endangered the life that grew upon it. Nobiliar faced criminals who sought to take wealth not their own as often as he put out fires or quelled floods. The other metahumans who used their powers to protect their world were hesitant to trust him, because he was a stranger from the stars whose war had wrought terrible destruction upon the Earth, and because instead of turning the metahuman offenders he captured over to the police, Nobiliar either forcibly depowered them employing Kheran science or imprisoned them in an extra-dimensional prison. Beyond that large issue of contention, another reason for the lack of trust was because he simply didn't have a life they could relate to.
Nobiliar was constantly active as a super-hero. Although he possessed a generally secret base of operations below the south pole, it was not a home or place of refuge for him. He did not have an identity where he pretended to be a normal human. And when they did, initially, extend and invitation for him to join their compact, Nobiliar declined. It was only until the galactic conqueror Deimos sought to make Earth his own and attacked with a force of demonic soldiers that Nobiliar took his place alongside Earth's native defenders.
