Hades

Hades is tall and robust, with bluish-gray skin. His hair is made up of flames that change color and size depending on his mood: Blue (normal), Pink (love, never seen), Red (anger/rage), Turquoise (surprise/sudden fright), and Orange (flirting/embarrassment, also never seen). The red and turquoise flames tend to increase in size. His eyes are yellow with black pupils, and he is usually neutral or wears a mocking/malicious smile. He has a sharp chin and a strong jawline, with a Greek-like nose. He is the tallest of the teachers. (Note: not by much.)
Its teeth are sharp, like those of a shark.

Hades has a great, sarcastic sense of humor; he almost always manages to trick you, and he's cunning. He's intelligent, but he gets angry easily when things don't go his way. He's not very patient, even though he seems very self-assured.

His style of dress would be Dark Academy: dark or brown suits, wool vests, long coats, and highly polished dress shoes. He usually wears silver or discreet rings, with his characteristic skull brooch pinned over his clothing where his heart would be.

His typical phrase as a teacher is; "If you don't study for the exam, we'll see each other sooner than you think. In remedial class, of course."
Or he'd say things to scare them and threaten them with failing, though he really just wants to frighten them. He's respected as a teacher and rarely raises his voice, since they're quite obedient in his presence in the classroom. He always explains things well and answers any questions; he's the typical neat teacher who rarely deviates from the norm. He's a history teacher, focusing on Greek history and the events of that era.
