BlackTiger

BlackTiger is the "meta-handle" for the player of Crimson Antarus, Crimson Prudhomme, Sanguine, and other characters.

Most often associated with a red-striped, black-furred tiger (sometimes with faint demonic traits such as horns or draconian features like wings,) most character overlap has more to do with the names available on different games than a separation of characters.
