Yo-Mitrix

The Yo-Mimatrix, better known as Yo-Mitrix (Japanese: ヨームニトリックス Yomunitorikkusu) is watch-like device which the series revolves on. It is currently worn by Ben Tennyson.

The Yo-mnitrix was created by Steve Jaws as a tool to allow the three main species, humans, aliens and Yo-kai, to interact and communicate with each other. This version of the Yo-Mnitrix is limited to a couple of people in the universe.

The Yo-Mitrix has five purposes:
 * To create communication between humans, aliens and Yo-kai.
 * It would serve as a repository for the DNA of over a million different intelligent species, preserving them in the event that any of them should ever become extinct and bring them back.
 * To teach species how is like being in another specie's shoes.
 * To act as a instant teleportation device.
 * To be used as a weapon.

Medal Scanning/Creating
When the user inserts a never before scanned medal, the Yo-Mitrix will say "Scanning (tribe)" which will create a more suit-for-combat version of the Yo-kai for use in battle, it will then shoot out a new medal with the transformation on it. Medal type depends on the Yo-kai scanned.

Trivia

 * Ironically, despite its watch-like appearance, it can't tell time. It's always stuck on 2.53 PM.
 * The hands only move when the Yo-Mitrix is summoning/transforming.
 * If you can't tell by now, this is a mixture between the Yo-kai Watch and the Omnitrix, as Echoson loves both series, he must have some sort of watch-fetish or something.
