Mephisto is a comic relief and joker, which is not your typical villain. He sometimes acts cheesy, incompetent, bumbling and has a short attention span, but can be capable of being intelligent despite his dimwittedness. Mephisto enjoys destroying things, and prefers elaborate spells and tricks and bragging about how he's a genius. He is also less coordinated, and has a mischievous and childish personality that can easily distract him from his and Praxina's missions at times. He is always loyal to his sister and would do everything for keeping her with him.
