Usapyon

is a Rank B Ice-attribute Merican Yo-kai of the Shady tribe.

USApyon is the partner of Inaho Misora, and one of the mascots of Yo-kai Watch 3 and the Yo-kai Watch franchise. He is also 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 the target of his anger, usually Inaho. When his rage is at its peak, he transforms into 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 uses a laser gun offically referred to as the "rabbit shot" (his exclusive item's name) and he shoots a big blue beam in the games, while in Vader Mode he shoots mulitple red beams which appear to made of electricity since in one episode when he shoots Inaho's chair it gets zapped and its "skeleton" can be seen. USApyon appears to be very strong, since even strong Yo-kai like Robonyan F and Sproink run from it. However, as Sgt. Burly states in Busters, he's a far-away attacker that is dependent on attacking from afar, and is nearly useless up close in battle. USApyon can activate Emperor mode, and when he does, he gains the ablity to fly and has a more powerful beam.

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 was reading a manga, which made USApyon use his Vader Mode to make her listen. He explains his backstory. He then ask her to find him so that he can apologize. Inaho refuses, but then he gave her the limited edition Sailor Piers figurine. After finding him, he promised that they will build a better rocket.

Inaho
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.

USApyon puts up a ton from Inaho, though his breaking point is when Inaho breaks something of his and doesn't apologize, which he proceeds to run away to Nate.

Despite everything they go through, USApyon and Inaho do clearly care for each-other.

Nate, Whisper, and Jibanyan
When USApyon arrived in Japan, he admitted he was looking for Nate. He shrugs this off after becoming friends with Inaho.

While USApyon is a little irritated with the three when they first meet, mainly at Whisper for mispronouncing his name as 'U-S-A-pyon', he is willing to work with them if need be.

Tomnyan
USApyon and Tomnyan first meet thanks to Nate and the two seem to hit it off rather easily and get along quite well due to them both being Merican Yo-kai. USApyon enjoys Tomnyan's singing, unlike the rest of the characters, he even danced to it. However, this does not stop him from turning Vadar Mode at him. In the anime, he teaches Tomnyan about Japan, since he's an American foreigner.

Costumes
USApyon can change his Elemental Technique's attribute, depending on the costume his is wearing, and were considered Rare Yo-kai. In Yo-kai Watch 3, they were later made separate Yo-kai, along with his B-USApyon costume, and stripped them of their Rare Yo-kai status, except for B-USApyon:
 * changes his attribute to Fire. In Yo-kai Watch 3, American Football Style instead has a Lightning attribute. The Medallium Bio for this style states: "USApyon in an American football suit. He's gonna try physical fitness for when he goes to explore the universe."
 * changes it to Lightning. In Yo-kai Watch 3, Driving Style instead has a Wind attribute. The Medallium bio for this style states: "USApyon in a race car driving costume. Apperently there's no need for good driving skills for when he goes to explore the universe."
 * changes it to Water. The Medallium bio for this style states: "USApyon dressed in a scuba diving costume. He seems to have the freedom to move around, to practice for when he goes to explore the universe."
 * changes it to Earth. The Medallium bio for this style states: "USApyon dressed in a costume that specializes in survival battles. For when he goes into space, he wants to polish his skills in case he lives in a tough environment."
