The Killer Hound is an enemy in Final Fantasy X-2. It is an extremely dangerous enemy as it is encountered early in the game, and its Killer Fang ability has a high probability of causing instant death, and it uses this ability often. Player should prioritize taking Killer Hounds first in order to avoid casualties.
In the Fiend Tale endings, a notable Killer Hound was trained as one of ancient Bevelle's fiend soldiers for the Machina War, 1000 years ago. Because of the machina chip embedded within him, Killer Hound escaped Shinra, simultaneously causing ancient machina in Zanarkand to awaken. The scene ends with Shinra suggesting the Gullwings capture one of these ancient machina.
