Pokémon Unite is a multiplayer online battle arena game, with standard matches consisting of two teams, each with 5 players.

TiMi, a Chinese video game developer, began a closed beta test in January 2021.

[12] In February 2021, The Pokémon Company announced that another closed beta test would be scheduled for March 2021, this time specifically for Canadian Android smartphone users.

[17] TiMi plans to continue development of the game after its official release, such as offering new playable Pokémon as downloadable content, the first of which became available for players on 28 July 2021.

[18] In January 2022, it was officially confirmed by producer Masaaki Hoshino that the game would be part of the Pokémon World Championships taking place in August, joining the main series games (known as VGC), the TCG, Pokémon Go, and Pokkén Tournament's last Championship Series season.

In a statement on the game's official website, he also stated that a tournament mode is in development, wherein the playing field would be evened for all competitors, regardless of the grade of their items.

MNL48's Team Padayon won the event after they defeated BNK48's Yummy Remote 3-1 in the Grand Finals.

[21] American team BLVKHVND won the first Unite Championship Series title in August 2022 in London, and in August 2023, the same American team, now competing under Luminosity Gaming, won the second Unite Championship Series in Yokohama.

[28] The game's microtransactions have also been criticized for their price, specifically, one of the customizable options for one of the Pokémon, Alolan Ninetales, costing US$40.

[35] By 1 October, research company Sensor Tower reported that Unite has been downloaded 30 million times for mobile devices, while The Pokémon Company confirmed that the game has been downloaded over 25 million times on all platforms by 4 October.
