Watcher

**Watcher** (ウォッチャー, *Wotchā*) is a term given to characters in who have been bestowed a Yo-kai Watch, regardless of model. The term was first officially coined in Yo-kai Watch 4.

The function of a Watcher is to serve as an envoy between the human and the Yo-kai World, those in possession of a Yo-kai Watch share the ability to call upon Yo-kai they have befriended. As of *Yo-kai Watch 4*, Watchers can participate in battle alongside their Yo-kai, with each Yo-kai Watch Master possessing their own weapon and Soultimate move.
