Just like his name says, he is an animal with fire-red fur. But under this fierce exterior is an intelligence surpassing that of any human's. Although he is forced to be a guinea pig in Shinra's sick experiments, not much else is known about this enigmatic character. It's not even certain Red XIII is his real name.

A powerful physical fighter, Red XIII is also a crafty magic user, who can stand lots of Materia. His sharp claws and fangs make him effective on the front line.
