This is a list of moments on The Thundermans during which either of the Thunder Twins were evil, voluntarily or involuntarily.

Phoebe went through hers in Come What Mayhem and Thunder in Paradise, under the influence of Dark Mayhem's powers. Max has wanted to be evil for almost all his life, until he chose to become good and train as a superhero.
