Ulysses Dragonblood is an ancient member of the Deviant race and a founding member of the Damocles Foundation. Mindful of the incipient power of human mutants, Ulysses, along with a bizarre coalition of dissident Eternals, Deviants, and humans; formed this organization in the hopes of controlling mutantkind. It is led by his brother, Odysseus Indigo. At some point Dragonblood comes to doubt the Damocles Foundation’s direction and comes into open conflict with it and his brother over the powerful mutant Arcadia Deville, who is able to manifest her thought-forms.

Dragonblood came to serve as the protector of Arcadia Deville, and while on the run from the Damocles Foundation, he at first came into conflct with Cannonball of X-Force, and then allied with him and X-Force against Argos the Hunter and members of Sword.

This deviant Deviant has demonstrated superhuman stamina, strength, and healing. He has the ability to sedate opponents with contact, and is unaffected by power-negation, at least that possessed by his brother. He has eluded and opposed an organization capable of imprisoning the powerful mutant Selene, the Black Queen of the Hellfiire Club. His allies include a powerful reality altering mutant (Deville), and the members of X-Force.
