Appearance.
Mephisto has dark purple hair, and forest green eyes. He is also tall, having a height of 195 CM (6'5"). He is usually seen in an elegant white outfit that consists of a white top hate with a pink and purple base, purple gloves, a tie that is pink with white dots, a white suit-shirt and undershirt, jester-style pants, and pointed shoes. His appearance prompts Kazumi to refer to his as The Clown. He stops wearing the pointed shoes and jester pants, rather putting on white suit pants, with black shoes.

In addition, he can transfom into a small white dog when he counts down from three in German. In this form he is a small, flufft, Scottish terrier-looking dog with a large pink rubbon around his neck, with a silver trinket attached to it. The trinket being the symbol for an Exorcist.

Personality.
Shrouded in mystery, one quickly learns of Mephisto's innate ability to act as if he knows more than what he is letting on. Careful and meticulous, he is like a chess plater, always ahead of the game.

He also enjoys chaso, as he stated to himself that he was a hell-rasier, and Assiah to be his playground, though he does not wish to see anyone get killed, claiming he himself would kill Amaimon if he ever tried to kill any of his students. He apparently 'loves' humans. When Mephisto first meets Amaimon, it is implied that he is conspiring with Satan and is most likely training Rin on his orders. He likes to make gambles with whoever possible, Including Fujimoro, Kazumi, and the True Cross Order.

He is prone to eccentric moments nestled in between serious moments, making light of a heavy mood and is portrayed as a man with more money than sense, but is very cheap when it comes to spending on others. Like his brother, he loves to eat sweets and he is deeply interested in the Japanese pop culture, proudly stating he is an otaku.
