Virizion is a stag or antelope-like, quadruped Pokémon that is primarily green. On the sides of its head are long horns that end in dull, curled points. It has a pointed snout with a black blaze running from its nose to the back of its head. Its face, hind legs, and underside are white. There is a pinked-tipped leaf on each side of its neck, and leafy tufts on its shoulders. On its back, there are pointed tufts of fur forming a medium-long tail. Its lower legs resemble knee-high boots with pink highlights at the knees, and it has black hooves.
Like the other members of its quartet, Virizion battled against humans in order to protect Pokémon. Virizion attacks its opponents by first darting around them with whirlwind-like speed before using its horns on its head. The horns are as sharp as blades. The blades are used to swiftly cut down opponents.
Pokémon Mystery Dungeon: Gates to Infinity: Virizion is a very popular Pokémon among the Post Town inhabitants, even though she has turned them all down at some point. The player first meets her after rescuing Dunsparce. Dunsparce had gotten lost looking for a crystal to give to Virizion as a gift, because he wanted to be her friend. Virizion turns him down, saying she doesn't have friends. This hurts Dunsparce's feelings, causing him to run away. After rescuing Dunsparce again, she asks to join the team. The player's partner immediately accepts, much to Emolga's chagrin. Virizion proves to be a calm and collected addition to the team, rarely outwardly expressing her emotions, but she changes as more and more is revealed about her past with her last friend, Keldeo. She later admits that she likes Emolga.

This Pokémon was unavailable prior to Generation V.
Virizion appears to be based on the character of Aramis from the novel The Three Musketeers. Like Aramis, it is the best at swordplay. Aramis in the novels was also the most feminine, vain, and romantic, qualities that Virizion possesses relative to its comrades. The shape of Virizion's head overall resembles a tricorne hat, commonly worn by Spanish and French musketeers in the 17th and 18th centuries. It physically resembles antelopes, such as the gerenuk or other species of gazelle. It may also be based on a stag. Like its comrades, its nose resembles that of a sheep.
Virizion may be a combination of viridian (a bluish-green color) or viridis (Latin for green) and champion.
