One of a few avian style characters I've got, this is Harmony Sarif. She used to be a normal girl. That all changed when she was involved in a fire. She was able to help the other people out, but she perished in the blaze, only to be reborn a few days later as an anthropomorphic phoenix. Since that day, she's learning how to control her powers into something useful for her.
