Name: Ignus (Everyone calls him Iggy but he hates that.)
Species: Pony/horse
Personality: Very mean and hot headed. The only reason he would do anything for anyone else is if he got something out of it. He is untamable and can breathe fire. His mane and tail are made of fire so he lives by a volcano to avoid burning everything down. (Not like he'd care of course.) When he is super mad his whole body catches on fire, his eyes glow red, and he loses control and goes on a rampage burning everything in his path.
Story: His parents were two normal, wild horses living in a giant herd. But right before he was born a forest fire started and the herd scattered. His father died in the blaze and although his mother made it out alive she had inhaled a lot of smoke and embers and was separated from the herd. When Ignus was finally born he had absorbed all the heat, smoke, and flames from the fire and was born as a fire-steed. His mother died soon after he was born so he grew up according to his own terms. Which meant fighting and killing to get what he wanted.
