Steve "Gooch" Yamaguchi is a supporting character in The Epic Tales of Captain Underpants.


The Epic Tales of Captain Underpants

Gooch is one of George and Harold's close friends. He usually ends up getting the short end of the stick and is not exactly good at school.

In "Captain Underpants and the Horrible Hostilities of the Homework Hydra", George mistakes him for Harold because they were both carrying a huge stack of books.

In "Captain Underpants and the Vexing Villainy of the Vile Vimpire", he chews George and Harold out for making fun of Erica. He is later attacked by Messica.

In Captain Underpants and The Flustering Mindless Woe of the Flushable Memory Wipes he appears as the first student George and Harold encounter after the memory wipes where he appears confused and disoreinted. Later he leads a mob to chase George and Harold upon the orders of Mr. Mudsley. He is one of the first students to shout out the real identity of their new principal as Ted Turdsley. He laughs at the various Ted Turdsley's who appear. Later after having his memory restored he states that he remembers everything even things he did not want to remember Implying he has some sort of Embarrassing or Traumatic memories.

Gooch becomes one of Jessica's Sophies in "Captain Underpants and the Abysmal Altercation of the Abominable Altitooth", even though he's a boy, he's called "Temporary Sophie" during the episode, and "Permanent Sophie" at the end until he gets fired since her real Sophies returned, he's also put under a rule that he's not allowed to talk, she means ever to no talking, and she's the leader in her Sophie group, he tries respecting her rules, due to Sophie One and Other Sophie getting taken away. 

In "Captain Underpants and the Confounding Concoction of the Crooked Combotato". George and Harold try to disguise him as Melvin to allow them to pass the ropes course. When Mr. Krupp questions him he explains "I'm actually not melvin , but you won't hear this because no one listens to me" before Mr. Krupp cuts him off and makes fun of "Melvin" for having a bad haircut. When they come inside he becomes confused as to his identity and Dressy and Bo start drawing on him When his turn to tell a story comes he asks whether he is supposed to be melvin or himself. When told himself he looks in the mirror before starting and says, hello stranger. George and Harold comment that they need to reboot Gooch before he tells his story. He continues directly where Jessica left off revealing that Captain Underpants and Combotato decided to join Popular High's gym decoration crew. This was a mistake as through a grant slapstick accident the pair destroy the gym and set off the scoreboard causing Captain Underpants to shout "Touchdown". After his time is up the group questions why he used slapstick at which point he comments that he was surprised too and that he must have more layers than he first thought. 


Gooch is an adorable 10-year-old Japanese-American boy. He wears his hair in a bowl cut and has blue glasses. His outfit consists of a pink shirt, blue shorts, and matching shoes.


Gooch is a very sweet kid but is also timid, insecure and pretty unfortunate when it comes to slapstick. Although he looks and acts dorky, he isn't a very good student and is not the brightest guy around, a contrast to the stereotype of Asian people being super intelligent. A running gag in season two and three is that animals often attack him. He has some trouble with his memory.


  • He looks similar to Harold's (maybe) future partner, Billy, from the twelfth book.
  • He also can play the mouth flute.
  • He has very little tech skills, as seen in season 2 and beyon.
  • According to the Halloween special, Gooch prefers St. Patricks Day, as opposed to Halloween. 
  • He appears in all episodes except for the ninth episode in Season 2, by being replaced by Choog.
