When Walker first runs into Danny in Prisoner's of Love, where Danny has accidentally piloted his dad's new Specter Speeder into the Ghost Zone, and Walker threatens to arrest him if he meets Danny again. Danny later encountered Walker after he enters the Ghost Zone in order to retrieve a present for his mother that he has accidentally sent there.

Danny. Walker overshadows the mayor and plans to have Jack Fenton elected as the head of defense against ghosts, thus rendering the town helpless against him. However, with a little help from Wulf, Danny defeats Walker and sends him and his minions back to Ghost Zone, though Walker's plan nonetheless succeeds, making Danny, Amity Park's Public Enemy #1. Walker makes a cameo appearence in Reign Storm, as one of the many ghosts fleeing from the Ghost Zone when Pariah Dark is destroying all of the ghosts homes. Walker also appears in The Fright Before Christmas was where he assists Danny in taking down the Ghost Writer after finding out that the Ghost Writer has broken the Christmas truce. After Ghost Writer was defeated, Walker had him placed in his prison, presumably because Walker states that the truce was a rule. He is then seen offering the writer an orange, which frightens him greatly and makes Walker laugh. Walker's next appearance is in Claw of the Wild, where he pursues Wulf and a number of other ghosts that have escaped the Ghost Zone. When he discovers that Danny Phantom is at a nearby camp, he quickly abducts the other campers to use as bait for Danny. But Sam dresses up as Wulf in order to fool Walker, and Danny, Sam, and Wulf defeat Walker yet again. Walker's final appearance is in Phantom Planet, as one of the many ghosts that helps Danny turn the Earth intangible.


Danny Phantom 08 194
Walker is extremely strict and a stickler for his rules in the Ghost zone. He always seek to punish those who defy him and his minions. He commands his prison and minions with an iron fist and goes to whatever measures he takes in order to preserve order, even making up laws as he goes along. He uses these rules as excuses to do whatever he pleases. Unlike most of Danny's foes, Walker hardly ever leaves the Ghost Zone. His direct interference with the real world is minimal, as he usually has his minions to do his dirty work. He also prefers using his minions instead of straightly attacking his opponents, though he will fight them if necessary. Walker seems to be a consequentialist, getting really low on his means for the sole reason of preserving his rules, or to get revenge on enemies such as Danny or Wulf. He is shown to have some spiteful sense of humor, always making brief jokes as he proceeds with his plans, especially in later episodes. He also shows signs of being a coward by having Wulf wear an electrical collar and almost putting the collar on Sam instead.
