Red XIII

Red XIII, real name Nanaki, is a red lion or wolf-like beast and one of the playable characters in Final Fantasy VII, who also appears in other entries to the Compilation of Final Fantasy VII. Red XIII is the name he received as a specimen designation while held captive and experimented upon by Professor Hojo, and remains the name he is called by the party and in battle in Final Fantasy VII. Although he is 48 years old, he is developmentally equivalent to a 15- or 16-year-old human by his long-lived species' standards. He fights alongside Cloud Strife and his allies to fulfill his duty to the Planet to defend it as a warrior.
