well, here's my teacher character ^^ I hope I didn't make him too powerful.
Name: Gallmin
Gender: Male
Species: Shadow Demon
Apparent Age: Mid-20's (human form)
Actual Age: several hundred years old
Appearance:
Bio: Despite being an ages old demon, and his kind's tendencies to hate humans, he's always been quite interested in humans, and when he had the chance to join the academy and teach them, he took the chance, and is now known as the constantly stoic
----
Powers: Control over shadows and darkness, able to mold the shadows and dark around him into weapons.
Down Side: Much more draining to use in light of any sorts due to having to generate his own shadows.
Weaknesses: His true form is weakened by light and holy powers, especially sunlight.
Fears(optional):
Items: Angelbane - A unique sword he created that he can summon at will, though only ever uses if he absolutely needs to, dealing with most fights using only his bare hands and shadow powers. The sword can't be summoned in bright light, due to being forged from shadows and darkness.
Extras(Like learned skills): Swordfighting, multiple forms of martial arts, various other much more mundane skills.(He's hundreds of years old. You don't get that old without learning a few tricks.)
