Jerko Phoenix is Justin's rival at WizTech. He is a champion 12-Ball player at the school, but lost to Justin during the finals. He was first seen in "Wizard School, Part 1," but is unknown if Jerko still is at WizTech as he didn't appear in the two-part episode "Saving WizTech" from season two. He wears an eye patch, so he doesn't wear have to wear the mandatory WizTech glasses. He is a parody of the Harry Potter character, Draco Malfoy.
- His name, Phoenix might be a reference from Harry Potter or Phoenix, Arizona.
