Dracozolt, Arctozolt, Dracovish, and Arctovish

Arctovish (), Arctozolt (), Dracovish (), and Dracozolt ()—known as Uochilldon (Japanese: ウオチルドン, Hepburn: Uochirudon), Patchilldon (パッチルドン, Patchirudon), Uonoragon (ウオノラゴン), and Patchiragon (パッチラゴン) in Japan, respectively—are a quartet of Pokémon species who first appeared in Pokémon Sword and Shield. They are considered some of the series' "Fossil Pokémon", species that are brought back to life through fossils. Unlike other fossil Pokémon, the quartet are composed of pairs of parts haphazardly put together, appearing to be inspired by the Crystal Palace Dinosaurs as well as similarly inaccurate reconstructions of dinosaurs.

The four have received a mixed response since their debut, with many citing their designs and lack of realism, though they have also been noted as being more interesting fossil Pokémon than past species. The Pokémon, most particularly Dracovish, have gone on to make an impact in the series' competitive scene.

Design and characteristics

Arctovish, Arctozolt, Dracovish, and Dracozolt are a quartet of species of fictional creatures called Pokémon created for the Pokémon media franchise. Developed by Game Freak and published by Nintendo, the Japanese franchise began in 1996 with the video games Pokémon Red and Green for the Game Boy, which were later released in North America as Pokémon Red and Blue in 1998. In these games and their sequels, the player assumes the role of a Trainer whose goal is to capture and use the creatures' special abilities to combat other Pokémon. Each Pokémon has one or two elemental types, which define its advantages and disadvantages when battling other Pokémon. A major goal in each game is to complete the Pokédex, a comprehensive Pokémon encyclopedia, by capturing, evolving, and trading with other Trainers to obtain individuals from all Pokémon species.
