Camerupt is a quadruped Pokémon that resembles a Bactrian camel. It has two gray volcanoes on its back. The two volcanoes on a female's back are bigger than those on a male. It also has a stout body with red shaggy fur and three blue ring-shaped markings on both sides. It has bangs on top of its head, droopy ears, and a tan furless muzzle.
As Mega Camerupt, the humps on its back have transformed into one large and very active volcano. Its fur expands and grows to a point where only its hooves can be seen, and its ears and the tufts on its head grow thicker and longer, standing on end. It gains a grey M on the front of its face and loses the three blue rings on its body. Magma is constantly bubbling up from within its body. It has a deep hatred of water or any moisture, and has an explosive personality and a short temper. The volcano on its back erupts constantly in an effort to intimidate its foes.
Its body contains amounts of molten lava of 18,000°F, which erupts out of its humps if the Pokémon is angered. As shown in the anime, it can become uncontrollably angry when it is struck in the face. It lives in the craters of volcanoes.
