Konstantin is Ring Man in his native universe and an android anywhere he's used as an OC, so he's one of my canon/OC hybrids, I guess. Has upgraded and redesigned armor in the Megaman X era, thanks to his Dr.Cossack descendant.

Very skilled in combat. Flashy and friendly but does not believe in mercy to his enemies. Able to generate metal-eating ring weapons made of nanomachines. Loves the planet Saturn because...yanno...ring. His weakness is high-energy weaponry, such as his brother's Pharaoh Shot, because it destructively disrupts his nanite generators.

Terrified of kids, the younger they are, the worse the fear. For him, they hit the same 'uncanny valley' that dolls, monkeys, or not-quite-truly-human-level-intelligence robots do for some other people. (Yes, he finds the child-like Megaman/Rock creepy as a result lol) Otherwise, he's confident to a fault.
