Shooter: "You're in big trouble, pal. I eat pieces of shit like you for breakfast!" Happy: "You eat pieces of shit for breakfast?" Shooter: "...NO!"
~ Shooter's most famous quote.
Shooter McGavin is the main antagonist in the 1996 live action film, Happy Gilmore. He is a talented but incredibly arrogant sportsman who delights in winning lots of money and praise while firing his caddies at will.
He was portrayed by Christopher McDonald, who also played Wilson Croft in Flubber, Kerr in Terminal Velocity, and Kent Mansley in The Iron Giant.
Shooter's villainy is mainly in his total inability to play nice when it comes to someone that may be better than himself: his tactics went way beyond the usual cheating of arrogant rivals as well since he hired a stalker to harass his opponent and committed all manner of crazy stunts to try and ruin Gilmore's chance at success. He allowed his jealousy and egotism to completely erode what few traces of honesty, good sportsmanship, and even just basic ethics he may have once possessed.
Furthermore, he has no problem with using people as his pawns to further his aims. For instance, Shooter professes some form of friendship with his henchman Donald, but it is clear that this is a lie: He really doesn't seem to like him very much at all, and only even talks to him when he's trying to persuade Donald to help him wreck Happy's chance at winning the championship.
He was also prone to trying to act like a schoolyard bully but his attempts at intimidation often backfired (as seen above). Also noted at the end his villainy became his downfall when he tried to take Gilmore's grandmother's house. Gilmore beats him in the championship, causing Shooter to lose the game.
Shooter, in a fit of hysterical, envious rage, steals Gilmore's Golden Jacket and attempts to run off with it. However, Shooter doesn't make it very far before he is caught and quite severely beaten up (off screen) by Gilmore's old boss, Mr. Larson, and a mob of angry spectators.
It is unknown what happened to shooter afterwards, but it's very likely that Shooter was banned from further PGA events due to his bad sportsmanship, so now he will never be able to get a golden jacket of his own.
Although he is the main antagonist of the movie he does not seem to be as evil as Hal as Hal is the sadistic manager of the retirement home where Happy Gilmore's grandmother lived briefly, forcing her and the other residents to perform hard manual labor and frequently giving them death threats. When dealing with their families, however, he put on a friendly and cheery façade and made it appear as though everyone was happy and being well taken care of. It is likely that, based on his behavior, Hal is a psychopath who was obsessed with control and exploiting the elderly residents for his own personal financial gain (for instance, forcing them to knit quilts for hours, which he would later sell). Because of this, he is arguably worse than the film's primary antagonist, Shooter McGavin who just wanted to win the Gold Jacket.
