He teams up with Drakken on several occasions when they have a common goal, as well as Monkey Fist at one point in "A Sitch in Time" (Although since that timeline was erased, as far as anyone is concerned, that particular partnership never happened.) Killigan faces off with Kim on a number of occasions, first when she and Will Du of Global Justice join forces to stop him from turning the entire planet into his own personal golf course. During "A Sitch in Time", he joins the other allied villains in traveling to the past in an effort to prevent their future defeats at Kim's hands, though they fail on each occasion. In the dystopic future ruled over by Shego in the film, Killigan becomes Robo-Duff: the World's Deadliest Golfing Cyborg, left with no visible parts of his body remaining except for his head in a wheeled exo-suit that enables him to produce exploding golf balls that he hits at his enemies.
