- Yo-kai Watch animation: Major Yo-kai.
A blue-skinned, child-like Yo-kai with a single grey eye and pink cheek markers. His outfit consists of white and grey Buddhist disciple clothes, along with straw sandals and a kasa hat.
Boyclops holds a certain amount of pride as a Classic Yo-kai, so much that when he, Lady Longnek, and Pallysol initially fails to scare modern youth, he feels depressed, so he decides to regain his skill by watching a classic horror movie.
Like Pallysol and Lady Longnek, he is very prone to bragging, to the point of being over-the-top.

Boyclops can be found in the Harrisville Station.
He can also be found at the Temple Park.
In the anime, Boyclops and his friends Pallysol and Lady Longnek first appeared in Here Come the Classic Yo-kai, in which they are searched by Nate in order to impress Bear and Eddie. The trio tries to scare the two boys, but fail, upon which they feel depressed. Whisper then decides to train them to regain their spirit, but they only manage to finally scare Bear and Eddie thanks to them having watched a classic horror film. After regaining their confidence, they give Nate their Yo-kai medals and go on a scare spree, which prompts a call-on to the Exorcist (which appeared in EP005) in order to send them to the other side. While initially inmune to his chants, they, along with Whisper and Jibanyan quickly begin ascending to the other side when the exorcist amplifies the sound of his chants, prompting Nate to use the Yo-kai Watch Model Zero to summon them back.

Boyclops is based on the youkai called hitotsume-kozō ("one-eyed youngster", also his Japanese name), appearing as a young child with a single eye and a bright red tongue, sometimes wearing a kasa hat over its shaven head. It doesn't possess any particular powers, but has a bad temper and a mischievous streak, and will harass people with childish pranks and greatly annoy them. Overall though, it is fairly harmless.
- He has similar summoning moves to Jibanyan.
- Boyclops' "random" nicknames in Yo-kai Watch 2 are: Peeper, Eyespy, Andrew, and Shady.
