Condor, and his counterpart, Swan were created by Hawk and Dove writer Sterling Gates and artist Rob Liefeld.
Condor makes his appearance at the end of the first issue of the Hawk & Dove series when he shows himself. He has a tendency to eat people while in the midst of a battle.
He fought and captured Osprey, an assumed carrier of the War Avatar, and allowed his partner, Swan, to kill him so she could gain her powers. He and her have a twisted relationship it seems. They latter leave for the White House where they take the President and Judge Irwin Hall hostage to gain the attention of Hawk & Dove. After Swan disappears from her fight with Dawn Granger, Dove takes her short sword and stabs Condor with it. This causes him to revert to his human form, which is actually an elderly man. While knocked out he is transported to a secure facility so Hawk & Dove can interrogate him.
He has no known ID on record, he dose appear to be British though. He mentions a War Circle that Hank Hall is part of and its because of it that he needs to kill him. He doesn't seem to understand the avatar of peace as well as war and so because of that he decides Dove should be killed as well. He alluded to secrets that are being kept by Deadman and says that having him around makes them easy to target. Durring this whole interrigation an unknown group of people come to bust Condor out, and Swan kidnaps Deadman to help them find the rest of the War Circle.
Putting Boston Brad in a chaos crystal makes him a usable key to cross into another realm Once crossing the barrier he crosses Swan and "feeds" off her letting him morph into a giant four eyed bird creature and fights both Hank and Dawn who have found him to save Deadman. He loses to Dove while crying for mercy. At the end of the battle Condor & Swan have disappeared.
It could be assumed that through the powers he has gained from killing thoes who are agents of the avatars he has now gained the ability to morph his body in a way that would allow him to actually eat the head of a full grown adult quite easily. The rest of his powers are the same as Hawks...for now. His powers have been able to keep him alive for around 200 years.
