Absol is a quadrupedal, mammalian Pokémon with a primarily white body with some dark blue coloration. It has a ruff around its neck and chest and a tuft on the top of its head adorned with a single blue-black oval. Between the dark fur, the curvature of the white fur on its head, and the positioning of its horn, Absol's face vaguely resembles a wu wei symbol. It has a feline face with almond-shaped, red eyes, a scythe-like tail, and a scythe-shaped horn on the side of its head. Its broad feet are equipped with three claws each, and dewclaw-like spikes protrude from the heels of its hind legs and the elbows of its front legs. It walks with a pacing gait like that of a bear.

Absol lives in the mountains far from civilization, and it rarely ventures down from its alpine home. Using its horn, Absol is able to sense even subtle changes in the sky and the land to predict when a disaster will occur and will try to warn people when one is approaching. Absol is also known to protect fields from natural disasters as well. This often has the unfortunate effect of Absol itself being blamed for the disaster, notably by the elderly. The hatred for Absol was started years ago by superstitions surrounding about it. Despite this, others are interested in its ability to predict disaster. Absol has been referred to as a bringer of doom. Absol can move as swiftly as the wind. Absol is said to have a lifespan of up to 100 years.

Forms

Absol can Mega Evolve into Mega Absol.

As Mega Absol, its fur is longer overall, and the increased energy coursing through its body makes the fur at the back of its mane stand on end so that it appears to have wings. The spikes on its heels and elbows grow larger, and the fur in these areas becomes longer as well. Its sickle-shaped horn widens, while an additional, smaller horn appears on the opposite side of its head. Its tail now has a more saw-like shape, and the oval marking on its forehead is now a rounded triangle.

Mega Absol emits a fearsome aura that has been known to kill fainthearted people from shock. It directs this aura at its opponents by beating its "wings", which are not capable of flight. However, Absol apparently detests assuming this form, as it normally dislikes fighting in the first place.
