Bio
I can tell you about my character, Ombato Hammerhorn. (The really big guy in the corner.) He's an ancient Lunar who has returned to the world upon hearing the rumors that the Solars have returned.
To his surprise, and horror, his old Solar friends have returned, but are now Abyssals. Instead of attacking them outright he discovers that they may not be as lost to him as he originally thought. Now he is on a quest to redeem his former friends. And if he can't, well, he'll cross that bridge when he comes to it.
Ombato, due to his age and experience, is actually quite calm and thoughtful. In his human form. As a human he appears and dresses like a southern plainsman, his original homeland. He is a tall willowy blackman covered in semi-glowing silver tattoos. He usually carries a spear in addition to his hammer.
In warform he lets the beast loose. His black rhino warform is an armored tank of a lunar with a propensity for extreme violance and cunning. Despite his hulking mass his is quick on his feet. A surprise he uses to his advantage very well. When he charges an enemy, gouts of flame flare from his nostrils and mouth. In addition to this he wears heavy plates of Moonsilver armor.
I hope that helps.
