Vivillon's wing pattern depends on the real-world geographic location set on the game the Pokémon was generated in. There are a total of 20 known patterns.
Vivillon is a butterfly-like Pokémon with wings that come in a large variety of patterns. Vivillon's thorax is an elliptical shape divided into three segments, each with a different shade of gray. Its legs are also elliptical which are black on the lower half and grayish on the upper half. Vivillon has two black, circular hands and no visible arms. It has a round, grayish head with large, black, pixelated eyes and a pair of skinny antenna. It can spread its scales to calm an opponent's fighting spirit, as shown in the anime. Its wings' pattern is affected by the climate in which it lives. Vivillon is the only known Pokémon capable of learning Powder by level-up, as Cutiefly can learn it by breeding.
Multiple Vivillon appeared in To Catch a Pokémon Smuggler!. They debuted in their Continental, Elegant, Garden, Icy Snow, Savannah, and Sun Pattern forms in this episode, in which they all evolved from a group of Spewpa.
In Dancing Vivillon and Burning Fletchinder, fifteen Sky Trainers were hypnotized by Malva and used fifteen Vivillon, each with a different Pattern. The Vivillon Patterns which debuted were the Archipelago, Continental, Elegant, Garden, High Plains, Icy Snow, Jungle, Modern, Monsoon, Polar, River, Sandstorm, Savanna, Sun and Tundra Patterns. The leader of these Sky Trainers, Yvette, has mentioned that she has 18 of the Vivillon Patterns, including the Poké Ball and Fancy Patterns. After their defeat and no longer being hypnotized the Vivillon safely land the Sky Trainers down in Shooting Frogadier. Yvette later uses a Marine Pattern Vivillon with her other Vivillon and in conjunction with Viola's Meadow Pattern Vivillon.

Vivillon is based on a butterfly. Considering the many different varieties of Vivillon that differ depending on the player's geographic location, Vivillon may have been based on divergent evolution or possibly species mimicry. Its blocky wing patterns may be based on pixel art.
Vivillon may be a combination of vivid and papillon (French for butterfly).
