Ooka and the others were working for Gozaburo Kaiba at first, but then conspired with Kaiba to overthrow him. When Kaiba betrayed the Big Five, they joined forces with Maximillion Pegasus, but he was defeated by Yugi Muto, so Gozaburo fired them, but was imprisoned in the virtual world by them. However, their Five God Dragon was destroyed by Yugi and Seto Kaiba, imprisoning the Big Five in the virtual world.They then joined forces with Noah Kaiba, entering his virtual world. As their bodies were destroyed, they needed to find new bodies to escape. Ooka dueled Katsuya Jonouchi, and took the form of the Judge Man, as his own deck master. He used a move called Clear the Courtroom to destroy Jonouchi's monsters and take off 500 life points for each monster. Although Jonouchi was winning at first, Ooka gained the advantage later on, and when Jonouchi played his gambling cards (like Demon's Dice, Angel's Dice, and Gamble), Ooka cheated by making the dice land on 1 and the coin land on tails when Jonouchi picked heads. Noah tried to pull the plug on him for cheating, but Jonouchi convinced him to let the duel continue, as he wanted to defeat Ooka and knew he had a chance if Ooka played fair. He used another gamble card, which Ooka lost, picking the wrong card, and he lost the duel and was digitized.
Ooka returned alongside Konosuke Oshita, Shuzo Otaki, and Kogoro Daimon, attempting to steal the bodies of Jonouchi, Shizuka Kawai, and Ryuji Otogi, but failed. They then entered Hiroto Honda's body at once, and dueled Yugi and Jonouchi. Ooka took control for one turn. After the Big Five were defeated, Noah gave them no more chances, and imprisoned them each in a different corner of the virtual world.
Ooka was killed along with Noah, Gozaburo, and the other members of the Big Five when Noah destroyed the fortress with a satellite attack, deleting the virtual world and everyone inside it.
Yu-Gi-Oh! The Abridged Series
In LittleKuriboh's parody series Yu-Gi-Oh! The Abridged Series, Johnson, as well as the other members of the Big Five, are executives of 4Kids Entertainment and are called Team 4Kids. Mirroring his status in the anime as an unjust lawyer, Johnson puts Joey Wheeler on trial, accusing him of copyright infringement (and for being an awful person), revealing he is responsible for getting LittleKuriboh banned twice on this false accusation. He calls up characters like Bandit Keith, Weevil Underwood, and Ghost Nappa, but is defeated when Joey counters by saying the fans appreciate Yu-Gi-Oh more and having Flame Swordsman (who says his name is Frank) attack him.
When he disguises himself as Mai shortly before the duel, he asks Joey if he finds him attractive, even after revealing his true identity.
He later returned alongside Gansley, Crump, and Lector to chase after Joey, Serenity, Tristan, and Duke. In Episode 54, all the Big Five were defeated by Yugi and Joey, and as punishment, Noah banished them to the darkest corners of the internet. Johnson was sent to the dangerous box, which he found to contain a lot of slander.
