idea: i have one.
Name: Ignis Quam Eleison/Eleison Quam Ignis (male/female respectively)
Gender: Both and Neither (see species, is usually male)
Age: Varies, but always between 14~30 (actual age will never be given out, and would be impossible to detect)
Appearance: Varies drastically, and will be avidly described whenever his form changes. As human, he always carries around the average longsword on his back, though infused with a crystal inside of the blade. The pommel of the sword can be pulled out after twisting to reveal a hidden thin-dagger with a crystal within the blade as well, which he has used on only a few occasions.
Personality: perceptive, street smart, brave, unorthodox in most mannerisms, helpful, and loves a challenge. hates one-sided or unbalanced occurrences, ignorance, and anything just given to him without any work or effort on his part.
History: Ignis lived throughout the early rising of mythical creatures before the humans decided to join forces and attempt to do what they always tried to do with everything else in their world: control it. He has intervened, assassinated, assisted, sabotaged, and watched both sides throughout the years, and has enjoyed it as if it was a game being that the weapons that the humans have made from the crystals have no effect on Ignis as long as he's in a human form, being that he takes on every physical aspect of what he is shaped as, but has never shown an ability to alter only a fraction of his body for an intended effect. As human, his body is the same as one, which goes for animals and other mythical creatures, which means that he can only speak in a body that allows for such, can only throw boulders in a form which grants such strength, etc etc. He himself, has a multitude of forms that he can take, ranging from the close to extinct hydra's species to that of a door mouse, though he can only stay in difficult forms for a short period of time. If knocked unconscious he retains the current form. He has also decided to intervene and assist the resistance to the Red Flood, as their numbers and tactics have began to be more than just a small nuisance.
