Petra Fina is an enemy of the Time Police wanted for stealing and messing up time and space from Flint The Time Detective. She allied herself with the Dark Lord out of having a "school-girl" infatuation with him. Though she eventually realized too late she was a pawn. When not on missions given to her, she takes the form of Ms. Iknow, a strict teacher of Flint, Sarah, and Tony's class. By the finale, she had a temporary truce with the heroes that only lasted until the Dark Lord was defeated.
