Finn is one of the secondary antagonists in the Jackie Chan Adventures series.
The Irish comedian and the brains (or at least the most intelligent) of the Enforcers. Finn has greyish-pale skin and red hair, which he wears with old-fashioned sideburns.
Finn is a 70s fanatic (in fact, his habitual dress is a white disco suit), and sang in disco bands at weddings before joining the Dark Hand. He frequently and jokingly refers to Valmont as Big-V (and Little-V when he is reduced to a child) and Shendu as "Shen-Dude". He has a nephew named Frank, who is unaware of his uncle's criminal background.
When a dragon, he has the ability to shoot fire from his fingers, and as a Dark Chi Warrior he assumes the jobs of his predecessor Rhen, and has a giant three sided shruiken for a weapon.
Finn and his compatriots Ratso and Chow appear as the first Dark Hand members Jackie encounters, at the same day Jade arrives from Hong Kong. When they threaten Jackie and attempt to damage several of Uncle's antiques (an attempt which Jackie's martial arts training easily foils), they spark Jade's attention and she decides to accompany her uncle henceforth on his quest for Shendu's talismans. Despite a long string of failures (and the accompanying bruises they sustain from Jackie, Jade and compatriots), they remain largely faithful to their boss, Valmont, even after his organization goes down the drain following Shendu's release and Valmont's subsequent (if accidental) possession by Shendu's spirit.
In the second season, however, after the Talismans are safely sealed in Section 13, there is one point at which the Enforcers split up and attempt to go their separate ways. After Finn suffers another nightmare - in the form of Jackie Chan spoiling even his more legit pursuits, he tries to open his own crime syndicate. Ratso and Chow join him (after Valmont has turned down a demand for a pay raise), but their attempt at their own career is short-lived, as Finn has foolishly decided to hunt down a cursed Irish emerald which brings its possessors bad luck. In this season, he gets his theme song.
In the third season, Finn, along with the other Enforcers, are forced into the servitude of Dalong Wong and turned into a Dark Chi Warrior, after Uncle captures their formers. He takes on an appearance similar to Rhen and wields a large, four-bladed shuriken-like weapon. When Hak Foo is turned into a Dark Chi Warrior, Finn and the other Dark Chi Warriors feared they wouldn't be called upon again, only to be resummoned when Hak Foo proved to not be enough. In the last episode of the third season, he is turned back into a human by Uncle, arrested by Capt. Black, and sent to prison.
In season four, the Dark Enforcers (Hak Foo included) work with Dalong Wong in an attempt to escape from prison. Dalong Wong, intending to summon Shadowkhan warriors, revives Tarakudo, who enlists the aid of the Dark Enforcers to find the Oni masks. While each of the Dark Enforcers eventually wear a mask, Finn has the unfortunate luck to sit on one of the Oni masks (animated by the Rat talisman). Despite being on his behind, the Oni Mask seems to have full control of Finn's body, making his fight while doing a handstand and attack with his feet. Finn eventually managed to remove the mask using the power of a potion stolen from Tohru.
In season five, Finn, along with the other Enforcers, are working at a petting zoo, when they are approached by Drago, and given the chance to assist him in acquiring the demon chi powers. They at first turned him down, but some persuasion (and a little dragon fire) changed their minds. Drago transformed the three into his dragon minions, giving Finn the power to fire blasts of flame from his hands. However, after failing their first assignment, Drago "fired" the Enforcers, changing them back to human form and leaving them for the police.
The Enforcers and Hak Foo made their last appearance in the final ep of Season 5 and helped the J-Team and the other Enforcers in the final battle against Drago. At that point, they had just been released from jail and were broke from serving evil forces and needed some kind of money. At the end of the episode, it seems that he and the other Enforcers have switched to the good side.
