Pikachu hitting Weavile with his Burst Attack in the Nintendo Switch version The title change may be due to the similarity between Pokkén and the German word for smallpox, Pocken. The official German-language title of the game is Pokémon Tekken. The Japanese characters ポッ拳 appear in the game's logo in both the Japanese version and the localized versions released in North America and Europe. Pokkén ( Japanese: ポッ拳, Hepburn: Pokken) is a portmanteau of Pokémon and Tekken.

The arcade version was published by Bandai Namco, the Japanese console versions were published by The Pokémon Company, and the console versions outside of Japan were published by Nintendo. An enhanced port for the Nintendo Switch, Pokkén Tournament DX, was released in September 2017. It was released for Japanese arcades in July 2015, and worldwide for the Wii U in March 2016. The game combines gameplay elements from Bandai Namco's Tekken series and other fighting games, such as 3D and 2D movement, with characters from the Pokémon franchise.

It is expected to experience stock shortages at retail in its first month.Pokkén Tournament is a fighting video game developed by Bandai Namco Entertainment. The Wii U will launch on November 18 in North America and November 30 in Europe. On the Nintendo 3DS, games released both at retail and in the eShop have so far carried the same price. It is unknown if downloadable Wii U games will carry the same discount in Europe and North America. The download will come at a discount, priced at 6,280 yen (£49 / $78) rather than the retail price of 6,980 yen (£54 / $87). Third-party title availability will be determined by each publisher, with Tekken Tag Tournament 2: Wii U Edition being the first third-party game confirmed for downloadable release. Nintendo has said that its first-party Wii U games will be available both at retail and as downloads in the Wii U eShop. The Wii U has an SD card slot to expand the system memory, and Nintendo has indicated that external memory can be used through the system's four USB ports. There is also the Premium Wii U console, which features 32GB of internal memory, of which the single game would use more than half.

The standard Wii U system only includes 8GB of internal memory, so if this is an indication of the typical Wii U retail game's size, the system is inadequately equipped to download even a single game.
