Jenni Anderson is Martin 's constant—and rather unrequited—love interest. Her view of Martin is generally not very flattering: this includes "immature", "freak", or "loser". Jenni is also one of the prettiest and most popular girls attending Torrington, her appearance being that of blue eyes, flared auburn-colored hair, black blouse and skirt, and knee-high boots. She is also Diana's best friend. Though, Jenni usually sees Martin as a "brat" well the moth man episode shows that Jenni has a crush on Marvin, the skate boarder guy that perfectly looks like Martin but there have been times where she is actually interested pursuing a relationship in him; when Martin acts like a gentleman. Unfortunately for Martin, though, it never lasts, because her mind is erased of what ever happened, or Martin does something stupid, or Jenni moves for a semester, or some other similar incident occurs.
She first appeared in the episode "Terror From the Sky".
She was voiced by Tabitha St. Germain.
