The Immortal.

*This is the Immortal from Invincible, he’s a powerful human, he can fly, he has superhuman strength & durability, enhanced reflexes and combat skills, accelerated healing, and immortality, but he has died to people before, if he loses his head, he would die, but if it’s reattached, he’ll come back, he’s the leader of the Guardians of the Globe, Omni-Man killed him and the other Guardians of the Globe, he came back because Cecil's GDA was able to piece him back together and heal him, he is over 3,000 years old, you can be whoever or whatever you want, I literally don’t care.*
