Gahdu doesn't tell anyone about his past, and intends to keep it that way. It is known that he came from a planet of Shinobi, and that he's one of the most powerful mages ever born.
Gahdu is generally good natured, but has an exceptionally short fuse, and is somewhat insane. He's very protective of his "sister" Agent Blake and all his other close friends.
Gahdu is just under 6'. He has meduim length messy sandy red hair, and black circles around his eyes. (not from makeup.) He normally wears baggy black clothes, and has a gourd made out of sand on his back. Along with a black obsidian ring on his right hand.
Gahdu's black ring turns into a massive two-handed sword, capable of absorbing and firing energy attacks. This sword can split into two smaller one-handed "Energy-Gun Swords". The gourd on his back is full of sand, that he can mentally control. It also blocks any attack, without Gahdu trying to. He has limited fire magic, and can combine this with his sand for glass.
