Gordon Walker was a vampire hunter whose methods often put him at odds with the Winchester brothers. He is turned by a particularly old vampire named Dixon who has a grudge against hunters. Later, Sam Winchester decapitates Gordon with razor wire, killing him. He now resides in Purgatory.
When Gordon Walker was 18 years old, a vampire broke into his house and abducted his sister. Gordon ran away from home, learned how to fight, hunt, and kill vampires, and tracked down the vampire who had taken his sister. He killed it, and his sister, who had been turned, marking the beginning of his hatred for the undead.
Dean and Sam Winchester first meet Gordon while tracking a vampire nest. Despite his assurances that he can handle them by himself, the two of them save Gordon's life and Dean starts to warm up to him because they are both hunters.
Sam, however, is wary of him, and calls Ellen Harvelle to ask if she's heard of him. She warns him that despite being a real good hunter, he is dangerous to everyone and everything around him and that they should leave him alone. Despite the fact that this particular nest of vampires do not harm or feed from humans, Gordon tracks them down anyway and captures their leader, Lenore.While he tortures her for the location of the other vampires, Sam and Dean arrive and try to persuade him to stop. It is then that Gordon reveals that his sister wasn't killed by a vampire, but instead she was turned into one so Gordon hunted down his sister and killed her. After Sam frees Lenore, Dean and Gordon engage in a fist fight, from which Dean emerges as the victor. The Winchesters leave him tied up inside of the house, promising to call someone to let him out in a couple of days.
While Sam investigates the murder of Scott Carey, another special child whose mother died in a nursery fire on his six month birthday, Gordon tries to kill him with a sniper rifle from a nearby rooftop. Dean finds where he is posted and fights him, only to end up being knocked unconscious and used as bait for Sam. While he converses with a tied-up Dean, he tells her that while he was performing an exorcism in Louisiana on a teenaged girl, she told him about a coming war, and that a demon has soldiers fighting in this war, special children with psychic abilities, which the demon has plans for. The demon said he knew one of them: Sam Winchester.
After revealing his knowledge about Sam's visions, and the brothers' connections at the Roadhouse, he announces his intent to track down and kill the special children, starting with Sam.Despite placing multiple tripwires attached to grenades near the backdoor of the house, Sam is able to set them off without harming himself and gets the drop on Gordon. After a short tussle, Sam knocks Gordon out, frees Dean, and they both exit the house. However, Gordon chases after them with guns in both hands, shooting at them. After hiding in a patch of grass, they watch as police cars roll up to the house and arrest him after finding the arsenal of weapons in his car, thanks to an anonymous call from Sam.
Gordon appears in jail and talking to a fellow hunter and friend, Kubrick, whom he convinces to go after Sam Winchester. He tells him that he is not even sure Sam Winchester is even human. Gordon Walker is aware of the brothers having opened the Devil's Gate. Gordon tells the hunter that they will have to break him out of prison.
- "Sam Winchester’s the AntiChrist." — Gordon Walker
A fight ensues in a warehouse where Gordon holds a girl he has kidnapped and turned into a vampire to use as bait. Sam Winchester decapitates Gordon Walker with a garotte improvised out of barbed wire during the struggle, thus ending the threat he poses.
- According to series creator Eric Kripke, Gordon was originally going to learn about the hunter Sam killed while possessed and use it to convince more hunters to turn against Sam. This was intended to be a story arc stretching over multiple episodes. However, Sterling K. Brown was contracted for the Lifetime Television series Army Wives, and Lifetime would only allow him to return to Supernatural for two more episodes only. 
- Gordon drives a red car with Michigan plates: TRI 208
- Used to frequent the Roadhouse around 2000-2001. Had some conflicts with Jo and Ellen, see Jo's journal for more details.
- Gordon keeps a hunter's journal.
- Gordon arguably hates vampires more than any other hunter shown however ironically, it did not take long for him to feed on an innocent human after turning into a vampire himself.
- Gordon is the first of three hunters shown to be turned into monsters: Gordon and Dean were both turned into vampires though Dean's transformation was reversed. Garth Fitzgerald IV was turned into a werewolf which is incurable, but has learned to live with it and adapt unlike Gordon and Dean who both wanted to die after being transformed, albeit after killing Sam in Gordon's case.
- Gordon's character may be a reference to Charles Gunn from Angel, also a vampire hunter of african descent whose younger sister was turned into a vampire, forcing the hunter to kill his own turned sister.
- Despite hating vampires, Gordon gets turned into one and dies as one. He also gives into the bloodlust very quickly. Dean also gets turned but he gets cured and manages to control his bloodlust for quite awhile.
