Ringo deceives others to achieve personal desires. When he is in power, he finds delights in destroying his enemies and their property by turning them into onion rings.
Ringo's hair is styled in a ring, similarly to an Onion Ring. He wears a burgundy kimono, brown shorts, a white apron, black boots with a red rim, and rectangular gray rimmed glasses. Ringo resembles Ronaldo in general appearance.
The placement of the gem in his hair loop triggers his transformation. Ringo becomes bigger and more muscular. He retains his glasses and brown shorts, but his kimono disappears. He transforms the apron into a tattered cape that wraps around his neck; it is tied at his waist with a ribbon. His black boots acquire a burgundy trim, and he carries a magical, red staff decorated with three gold rings.
He wears white fundoshi-style underpants.
In the episode "Garnet's Universe", Ringo first appeared when he fell out a tree. After Garnet "revived" him, he tried to deceive Garnet, Hopper, and Hoppy into believing that he was the guardian of the shrine and that Foxman stole his powers and banished him. After successfully tricking Garnet, Hooper, and Hoppy, they travel to the shrine (similar to a Mario game). Upon reaching the shrine, they find Foxman looking at cats on a website similar to Tumblr. Garnet battles Foxman but ends up losing the battle due to his power. After Garnet trains and returns to battle Foxman, she manages to defeat Foxman but he reveals that he was the actual protector of the shrine and Ringo was trying to steal it so he can become Ultimate Ringo. As Ultimate Ringo, he manages to turn Foxman into an onion ring and transports everyone to the Ringo Zone. After a long and fierce battle, Garnet manages to defeat Ultimate Ringo out of love for Steven.
