Christian Walker is the main character starring in the comic book series Powers. He was created by writer Brian Michael Bendis, artist Michael Avon Oeming. Originally published through Image Comics beginning in 2000, but in 2004, it moved to Marvel Comics, where the series launched Marvel's Icon Comics division for creator-owned titles.

Christian Walker's origin was explored in the story arc "Forever" in Powers (vol. 1), issues 31 to 37. Initially thought of as a boring, two dimensional character due to his lack of conversation (which has since been put down to a feeling of having had "every discussion before" like an "old man that couldn't be bothered to finish his sentences" in the letters pages of the book) the origin was acclaimed for its originality and filled out some of the questions surrounding Walker, while further raising some more.

It all started at the dawn of man, when two Cro-Magnon men have a disagreement over a woman and start fighting, both surprised and confused to find that they have powers. The fight rages on for days and destroys everything in its path as the first super powered battle, eventually tiring them out. They walk away from each other in a stalemate. One of these first ape-men was Christian Walker.

In the Powers 2008 Annual, it is revealed that Walker and his rival clashed once again, this time as full homo sapien cave-dwellers. Walker, now known as Gor, has retired to a desolate cave where he sat alone for many years, simply metamorphosing to 'higher' forms of hominids (Evolution describes how species separate,, not changes in individual life forms). Over time, Gor attracts a tribe, and becomes something like a worshipped chief to his people. When one of Gor's men is killed by a wound not made by teeth or claw, Gor is forced to investigate, following a trail that leads to his old rival. Gor's rival, now calling himself Blood Fist, has invented the world's first stone weapon (a knife made of rock and bone, suggesting he has a tendency to out-pace Walker in evolution) and has used it to violently take over a tribe. Now Blood Fist is preparing to challenge the tribe's "cave god", an enormous bear to which the tribe pays tribute, and claims to be a god himself. Remembering the two's past encounter Gor resolves to end their fight once and for all, and moves quickly into the cave, killing the bear with his bare hands and ripping off its skin. Gor challenges Blood Fist while wearing the bear skin, rejecting his words and claiming that they are both just men. Finally, Gor apparently ends their fight by stealing Blood Fist's weapon and stabbing him through the skull.

Christian Walker has not been a contender in any CBUB matches.
