Gau is a playable character in Final Fantasy VI. He is a feral child who grew up on the Veldt.
Gau is a teenager with wild hair (blondish-brown on his sprite, but green in artwork). While he's of average height for his age, he walks with bad posture—occasionally on all fours—and wears tattered clothing fashioned from animal skins.
Having grown up alone in the wild, Gau has no concept for etiquette or grammar and often refers to himself in the third person. In some situations, he calls out "gau!" even if the player doesn't name him this. Notable for a boy of his origins, he has a fair understanding of human language despite his often improper use of it. He is knowledgeable enough to understand certain sensitivities, such as mourning the dead. Gau has a keen interest in shiny objects, hoarding them in a cave on the Veldt. He is afraid of heights.
Gau is fond of human contact and becomes attached to Sabin and Cyan upon being given food when hungry. His commitment to the party runs deep, as he partakes in several battles despite lacking a major reason to do so. Furthermore, when the party becomes divided, Gau submits himself through rigorous training in the Veldt to strengthen himself to help the others, seemingly trusting that his friends would look for him.
Gau can be considered a rather innocent, pure-hearted boy. When he has a chance to meet his father, rather than express anger or sadness, Gau is happy that his father is alive, not holding any grudges.
