Duff Killigan is an irate Scotsman with a strong accent, who turned to crime once he was banned from pro golf. He proudly calls himself "The World's Deadliest Golfer" and uses exploding golf balls as his weapon of choice. Since his first appearance, he has shifted into a mercenary role, stealing technology or kidnapping people for the highest bidder.



Duff Killigan is a Scottish man who wears a green and red tartan kilt, which is a type of skirt commonly found in Scotland and sometimes Ireland, although the tartan pattern makes it the former.

He wears a purple shirt with the kilt and has a white sporran pouch with a blue rhinestone clasp for holding items. He also wears a green tam hat. He has a darker reddish hue of hair has a full beard and no mustache.

Dark eye color either Dark Green, Dark Hazel, or a mix of Brown and Hazel or Brown.


He has a boisterous and brusque personality.


Duff Killigan's combat style combines his love of golf with explosives in a surprisingly effective manner. He possesses a speedy and highly accurate golf swing, which he uses to launch exploding golf balls at unsuspecting opponents. He has also wielded two golf clubs as direct weapons themselves, an idea inspired by Kim Possible during their first encounter.[1]



Killigan was once a professional golfer, but he turned to a life of crime after being banned from every golf course in the world, including mini golf, for excessive displays of temper.

Killigan first encounters Team Possible after he kidnaps former weapons researcher Professor Sylvan Green. His plan is to use Green's more current research on rapid grass growing to convert the world into a giant golfing green, starting with Japan, the first country to ban him from golf. Kim defeats him by using super fertilizer on dandelion seeds and encasing Killigan in them.[1]

Killigan next appears attempting to sell a stolen, experimental cybertronic battle suit, dubbed the Centurion Project, to Dr. Drakken. Kim interrupts the sale, which results in Killigan both losing the battle suit and failing to get the money that Drakken promised him. Killigan then kidnaps Ron in hopes of forcing Kim to surrender the Centurion Project, unaware that it has temporarily bonded to her. Aided by the battle suit, Kim defeats Killigan, Drakken, and Shego, and the three villains are arrested.[2]

Killigan, Shego, and Monkey Fist each attempt to steal a valuable microchip that was accidentally swallowed by Rufus. They fail, due largely to heated competition among themselves, and Kim's interference.[3]

Killigan is briefly visible during Señor Senior, Junior's prison dance routine.[4]

Due to Shego being sick with a cold, Killigan joins forces with Drakken. While they argue over terms, Ron manages to recover the stolen Ray-X from them. When Drakken also falls ill, Killigan hires temporary lackey Hank Perkins as his sidekick, and they re-steal Ray-X. Killigan then catches a cold, which left Perkins to run things.[5]

Ron and Rufus sneak into Killigan's castle looking for a library book that Ron lost on a previous mission. They interrupt Killigan's lunch of haggis, and he forces them to join him, much to their disgust.[6]

Killigan makes only brief appearances in Kim's Senior year. He is one of several villains interested in buying HenchCo's molecular transducer, and joins the rest in pursuing Kim once she stole it.[7] Shortly before Kim's homecoming, Killigan kidnaps computer programmer Ricky Rotiffle. Killigan is quickly captured and handed over to Global Justice.[8]

Kim and Ron investigate Killigan shortly before their graduation, suspecting him of a vandalism spree of various golf courses. As it turns out, he himself was a victim of the same, and has installed a new security system on his island for that very reason.[9]



"Gram" Killigan

Killigan briefly referred to his Gram Killigan and her haggis recipe, which he still made for himself on occasion. He apparently held her in such high regard that in his castle, it was his ironclad tradition that no one refused to eat the haggis once it was prepared.[6]

While Duff Killigan generally preferred to work alone, on occasion he did agree to temporary partnerships or assistance. In particular, he worked with Dr. Drakken and Shego more than anyone else, either attempting to sell them stolen technology, or putting aside personal differences long enough to achieve a mutually beneficial goal. Killigan did not actually seem to like either one, because while he did find Drakken's bumbling to be amusing, they were rivals first and foremost, and consequently found themselves in pursuit of the same technology at times.

Ron: No, you got it all wrong. She's with her parents.
Killigan: What?
Man: Oh, another trick or treater. (Duff puts his hand out for a piece of candy from the man) Happy Halloween. Piece of advice. The girl costume works better without the beard.

Alternate Versions

Future Killigan/Robo-Duff

Killigan joins forces with fellow villains Monkey Fist, Drakken, and Shego. The four steal and combine the two halves of the Tempus Simia idol, and use it to travel into the past, in an effort to attack Kim during vulnerable moments of her life. Killigan, Drakken, and Monkey Fist are captured after a failed attempt to crush Kim as a middle school student, but Shego escapes with the Tempus Simia. This results in a dark future timeline where Shego rules the world, and Killigan is among her henchmen, though greatly changed: he is then the self-professed "World's Deadliest Golfing Cyborg", which Ron notes as not being a crowded field, now known as Robo-Duff. He is tasked with capturing the future versions of Wade and Jim and Tim Possible.

The destruction of the Tempus Simia virtually erases this adventure from history.[10]
