Usapyon

is an Ice-attributed Rank B Merican Yo-kai of the Shady tribe.

USApyon is the partner of Inaho Mizora, as well the mascot of Yo-kai Watch Busters: Moon Rabbit Team.

Biology
USApyon wears a yellow spacesuit that has rabbit-like ears on the hood, and he carries a small orange ray gun modeled after a carrot. He also has a blue jet pack attached to his back. USApyon has another mode known as where a glass plate flips over his face, black smoke fills his helmet, and his eyes turn red.

While in Vader Mode, USApyon typically shoots at his target of ire, typically Inaho. When his rage is at its peak, he engages in, where he gains pink armor and a teal-green cape. His Vader Mode-like eyes are also noticably thicker and gain a spike. USApyon's gun has also changed colors to reflect Emperor Mode.

USApyon used to be an otter that was later named "Chibi" that ended up in a rabbit farm for some unknown reason. In Corocoro comic, he was bullied by other rabbits for being different from them. One day, he was selected by NASU for the first animal into space. But when they tried to test Chibi with a rocket engine, he panicked and got electrocuted by the circuit board and the rocket exploded. In Chibi's death, USApyon was born.

In the anime
USApyon made his debut in Episode 77 where he tells Inaho to buy a space watch which later turned out to be a Yo-Kai Watch U Prototype. After Inaho summoned USApyon, he asks her for her help but she was not interested. He then begged her to listen to his story which he explains that he is looking for a person. After explaining who the person is he is looking for, he tells his background. But Inaho did not listen and was reading a manga, which USApyon used his Vader Mode to make her listen. He explains his background story. He then ask her to find him so that he can apologize. Inaho refuses, but he gave her the limited edition Sailor Piers figurine. After finding him, he promised that they will build a better rocket.

Inaho Mizora
Frankly, USApyon sees Inaho as a bit of a dummy. He gets annoyed by Inaho's antics often, sometimes causing him to go Vader Mode on her.
