The eighth generation (Generation VIII) of the Pokémon franchise features 88 fictional species of creatures introduced to the core video game series in the 2019 Nintendo Switch games Pokémon Sword and Shield as of patch 1.2.0. The starter Pokémon were the first Pokémon of the generation to be revealed on February 27, 2019.

A major change in the eighth generation compared to previous ones is that Pokémon and forms are introduced via game patches instead of exclusively through new games.

Development of Pokémon Sword and Shield began in 2016, immediately following the development period of Pokémon Sun and Moon. The conceptual phase lasted approximately a year and the debugging process continued into 2019.

Through its lifetime, new Pokémon and forms have been added to the generation through game patches. On January 9, 2020 with Sword and Shield patch 1.1.0, Galarian Slowpoke was added to the game. In June 2020, legendary Pokémon Kubfu and Urshifu are planned to be added, followed by Calyrex and it's steed Glastrier and Spectrier in fall 2020.

Zamazenta has not been a contender in any CBUB matches.
