Skewer-Happy Yakitoro

From the day they're born to the day they die, Yakitoros have but a single passion: charging at their enemies to run them through like a kebab. This instinct develops at a very young age, well before their horns appear, and drives them to run headlong into everything around them. Over the years, the hunched back that results from all of this charging grows larger and larger as a symbol of their self-sacrifice. So if you ever come across a Yakitoro with an enormous hunchback, it's best to just stay away.
