Mallory Casey used to be a student being tutored by Tech. Apparently she was working on a project that can ampilfy brain waves, but her true motive was to drain the intellect from the professers from the academy. But was foiled by Tech. This caused her to grow a huge head and a thirst for revenge against Tech. Before the incident, she had an average sized head and wore glasses but after the incident, she had a huge head and wore violet lightweighted suit. She is the archenemy of Tech E. Coyote.
- Technokinesis: She can make a weapon out of any metal and surprisingly paper clips too. Because it was shown in "The Menace of Mastermind" that all her papers or books have every staple taken out.
- Ferrokinesis: The ability to control and manipulate the shape of metal. A perfect combination with her technokinetic abilities.
- Voiced by the late Florence Henderson.
