text: Diana's best friend. Jenni is one of the prettiest and most popular girls attending Torrington. She has blue eyes and flared auburn-coloured hair, usually seen wearing a black blouse and skirt with knee-high boots. Martin is in love with her, which she does not return due to his immaturity. She regularly describes him as "immature", a "freak", and a "loser". However, there are times she becomes interested in him, particularly when Martin acts like a gentleman. Unfortunately for Martin, this never lasts due to her memory being erased, or Martin subsequently doing something stupid.
  Marvin (voiced by Matt Hill):
  Martin's rival. The son of a pilot, Marvin enjoys the extreme, saying that he enjoys the adrenaline rush that comes with such activities. Some of his activities includes rock climbing in the Himalayas, parasailing over the Great Barrier Reef, street-luging on the German Autobahn, jungle kayaking, and snowboarding down the face of K2. His talents and popularity make everyone at the school fawn over him, while making Martin jealous.
  In "The Third Eye", Marvin is recruited to work for The Center, which annoys Martin. At the end of "Body-Swappers", he is relocated to Hawaii as a reward for his work on the mission. However, in "Rage of the Leprechaun", he is relegated to The Center's South Pole facility because of his negligence in a previous mission, and blames his unfortunate circumstances on Martin.
