The Yo-kai Tribes (Japanese: 妖怪の種族 Yōkai no Shuzoku) are different groups that every species of Yo-kai is divided into. In battle, two or more adjacent Yo-kai in battle that hail from the same tribe receive a special Tribe Unity bonus, giving those Yo-kai a special boost to a stat that is best exemplified by that tribe.
In the games =
The first Yo-kai Watch game introduced 8 tribes, with a 9th group called the Legendary Yo-kai, though they are not a separate tribe in themselves, as those Yo-kai still belong to one of the eight Yo-kai tribes.
In Yo-kai Watch 2: Bony Spirits and Fleshy Souls, an official 9th Yo-kai tribe, the Wicked tribe was introduced, though it wasn't until Shin'uchi that the Wicked tribe Yo-kai could be usable in battle, and even then, only the Wicked Executives and the Wicked-controlled Classic Yo-kai had any Yo-kai Medals to give.
In Yo-kai Watch Busters: Moon Rabbit Team, Lord Enma was introduced with a new tribe known as the Enma tribe.
In Yo-kai Watch 3: Sushi & Tempura, the existence of a eleventh Yo-kai tribe, the Hagure tribe, was leaked via CoroCoro magazine following the finalist results of fans submitting their designs with the first and only Yo-kai being Android Yamada.
In Yo-kai Watch Shadowside, the old tribes have been replaced with 7 new tribes (Goriki, Onnen, Mononoke, Tsukumono, Uwanosora, Omamori and Mikakunin).
