List of Great Teacher Onizuka characters
This is a list of the characters that appear on the manga, anime, and live-action series, Great Teacher Onizuka ("GTO", for short). A 22-year-old, blonde-haired biker, virgin, and former bōsōzoku, Eikichi Onizuka is the protagonist of GTO. He graduated from a bottom-rung university by cheating and, as such, cannot get a decent job. His primary way of spending time is peeping up girls' skirts at a local mall. He is very athletic and has a second dan black belt in karate. Holy Forest Academy faculty and staff. Eikichi  Onizuka. Onizuka decided to become a teacher. His initial training is in the Musashino Public High School, where he meets Nanako Mizuki. His experience taming the rowdy gangs in his assigned class hardens his convictions that teaching is the way to go. And when he learns of Mizuki's problems, he also decides to abstain from sexual experience with schoolgirls, opting to solve their personal issues instead. Unfortunately, he forgets to take the public teachers' civil service exam; as a result, no public high school will accept him, but he is still eligible for private school teaching. He manages to  get a job at the Holy Forest Academy, despite the objections of Vice-Principal Hiroshi Uchiyamada, whom he continues to aggravate well into his tenure. One of the conditions of having the job at Holy Forest is that he must sleep at the school – in the storage room at the top floor, with roof access – and it is here that Onizuka officially starts his career in teaching, when he stops Noboru Yoshikawa from committing suicide. Onizuka is put in charge of class 3–4, a class so bad it has driven past teachers insane and one to death. Not only does  he survive their brutal, bullying tactics, but he also befriends his students, and the backbone to the story of GTO consists of his unique experiences in turning his students around and learning lessons of his own. Onizuka is capable of great feats of strength, such as arm-wrestling over 100 men of exponential strength, (sometimes 3 at once) in a row and winning. He is also an experienced martial artist, as Onizuka is capable of fending off multiple opponents, even if they are well-armed. However, it was revealed around chapter 190 that because of all the physical damage he  sustained since he started teaching, it resulted in a clotted blood vessel in his brain, and that a jolt to his head could either turn him into a vegetable, paralyze him, or kill him. In spite of his impressive fighting skills, Onizuka is often roughed up by his students, and others, whenever he behaves badly. It could be speculated that deep down, Onizuka knows when he's acting immature, and allows others to keep him in line. An example of this is when he forces his students to dig for buried treasure during the Okinawa trip. Urumi Kanzaki kicks Onizuka  into a hole, and later forces him to wear S&M garb and has him crawl around on all fours, with Urumi riding on his back. Another example is when Vice-Principal Uchiyamada has Onizuka over for dinner and hits him on the head with a wooden bench after finding out that he was acting lecherous with his daughter at a karaoke bar (Onizuka was playing "Where's The Nipple?"). His mode of transportation is a Kawasaki Z750RS Z2 motorcycle, and is also the protagonist in the GTO prequel, "Shonan Junai Gumi". It is shown throughout the series that Onizuka is  also very lucky, as he always manages to squeeze out of tight situations. An example of this is when he must raise 8 million yen to live up to a promise he made to the 3rd year students. He received what he believed to be a winning lottery ticket, but it turned out to be false. However, he was given a raffle ticket which he kept but didn't expect for it to help his predicament, but ended up winning a Mercedes-Benz E-Class car worth the 8 million yen. He gave away the Mercedes in an act of  kindness, and while it seemed unlikely for him to get the car back, it was returned to him in the last minute. GTO-Shonan 14 days In Shonan 14 Days, Onizuka revealed on a live television program that he nearly buried one of his students for thinking that she is dead. Although he denied the claim that he did this on purpose, the crowd did not take it and Onizuka was forced to leave Tokyo for a while until the outrage subsides. He goes to Shonan, a place where he grew up. There he met Shiratori, one of Fuyutsuki's  friends and he learns that she is a caregiver at the White Swan Youth Home which houses kids from broken homes. He tells her that he is a teacher back in Tokyo and he probably could give her a hand in managing the kids at White Swan. Shiratori invites him to stay with them and help out, and Onizuka obliges in order to help the kids in the same manner he does at school. Onizuka mentioned a little about his dad, who left his mom when he was younger for another woman when he shows Katsuragi his secret place, a  place where he goes when he is stressed out or in trouble. Katsuragi thinks that she might have misjudged him and started to think of Onizuka on a different perspective after that. GTO:Paradise Lost The next stage for Eikichi Onizuka: Kissho Academy's Class G, a newly established class for young celebrities. But as Onizuka soon finds out, his new teaching assignment is no superstar paradise—it's a super problem class, feared by all!
