Jackie Wackerman is Kick's biggest and scariest fan and also his resident stalker. She first moves into the neighborhood in "Obsession For Kick" and demonstrates her stalkerish tendencies. Kick is (initally) appreciative of the attention, causing Gunther to become jealous, but soon begins to be disturbed by her. She is known to have several collections of Kick's items, such as a replica of his bedroom, a signed autograph of him, and his bandages.
She wears a blue shirt, under a white and green polka-dot shirt, red pants, blue shoes and dark glasses. She wears braces, brown short hair, and pale skin,
She has an intense obsession with Kick, mainly due to his daredevil nature. This is exploited by Gunther in "For The Love of Gunther", but her affection for Kick soons revert back to normal. As seen in "Obsession For Kick", she has a wide collection of Kick-related merchandise, among them being used bandages. Naturally, Kick doesn't reciprocate such obsessive behavior.
Gunther is known to have a crush on Jackie, mainly due to their shared interests (such as their Viking heritage). In "For The Love of Gunther", this is returned, but has since reverted for unknown reasons. However, it is to be noted that Gunther has not done any stunts since this episode, and the fact that Jackie likes daredevils will always hold true.
While Jackie sees Kendall as an enemy and rival for Kick's love, Kendall just sees Jackie as an annoyance, and likely doesn't see her as a rival in that way. But in "Roll Reversal" Jackie is her biggest fan.
