Buneary is a small, bipedal, rabbit-like Pokémon with brown ears that can curl up. It has two types of fur covering its body: a light tan fleece that covers much of its lower body, feet, and the tips of its ears, and a smooth, chocolate-colored pelt on the upper half of its body. It has a small, triangular pink nose, pink paw pads on the undersides of its feet, and small tan spots above its eyes. It has a small brown puff of a tail.

Buneary almost always keeps one of its ears rolled up. Although Professor Laventon had hypothesized that this is done to protect its hearing, in actuality, Buneary rolls its ears so it can quickly unroll them and launch them as an attack. The attack is strong enough to hurt grown-ups and crush boulders, and increases in power as Buneary trains to use it. Buneary can also use this technique to jump really high, by slamming its ears towards the ground. Buneary's arms and legs are weaker by comparison. If Buneary senses danger, it perks up both ears; conversely, if Buneary rolls both of its ears in, it is a sign that it is unhealthy. On cold nights, Buneary sleeps with its head tucked into its fur. It lives in forests, though it can also be found on icy mountains.
