Game: Final Fantasy VI

Shadow's only friend is his Doberman, Interceptor, and that dog will hunt.

Interceptor is a ruthless companion who will take damage in Shadow's place in dire situations, often following up with Wild Fang or Take Down, which serves up massive damage to the enemy. Interceptor's loyalty to his human doesn't die even if you let Shadow. Should Shadow fall on the Floating Continent, Interceptor is trusted to Shadow's daughter Relm.
