Zyphrix, the phoenix with a human form

Unlike the other phoenixes, Zyphrix isn't always present. When he submerges himself under water, he extinguishes all of his flames, and comes out of the water as a man. Tall and handsome, without a name that nobody knows, even himself.

The man was never born to any human, he was created by Zyphrix's love for a girl whom he could never be together with as a phoenix...

But if the man wants to become Zyphrix again, all he needs to do is come into skin-contact with natural, not magical, fire. He doesn't like to do this very often, but in some situations he has no choice.
