"Luigi Vendetta" is the 15th episode of Season 2 of Kick Buttowski: Suburban Daredevil.
Kick fights Brad again at the Mellowbrook Mall, but Brad is beating him badly. Then he notices how Pantsy seems to be obeying Mouth. Mouth advises Kick to go see Luigi Vendetta. Kick is at first reluctant but eventually goes. He finds out that Luigi is really a kid who promises to take care of Brad once and for all. Kick then goes to a movie and becomes paranoid when an actor says the same thing Luigi said. He then follows Brad all over town till he breaks down, confessing to Brad. Brad is skeptical, so he hangs Kick upside down. But while he does this, Luigi shows up, and sings an annoying song to Brad till Brad breaks down, promising to be good. Then they see Mouth now obeying Pantsy, who advises Brad to go see Paddy O' Payback.
Luigi is in Kick's living room singing the same annoying song to skeletons of Kick & Gunther.
