How Kazuya joined the Tourney
After he had killed the G Corporation officials who betrayed him, Kazuya Mishima succeeded in taking control of the corporation from behind the scenes. In the meantime, the world was quickly slipping into chaos due to the activities of the Mishima Zaibatsu, led by Jin Kazama. Kazuya could never accept a world controlled by anyone but himself, and he set out to use the military power of the G Corporation to suppress the Mishima Zaibatsu. At this point, the G Corporation was praised by the nations of the world for its heroic actions. When the G Corporation's public influence had become great enough, Kazuya used it to announce a hefty bounty for anyone who could capture Jin alive. In reply, the Mishima Zaibatsu announced the Smash Bros. Tourney. This was just as Kazuya had predicted, and it put a satisfied smile on his face.

Snake's Codec Conversation
- Snake: "Otacon, I see a shirtless Asian man with a scar on his chest."
- Otacon: "Snake, it's Kazuya Mishima! Heihachi's son!"
- Snake: "I read him Time Magazine, about G Corporation."
- Otacon: "Years ago, when Kazuya was a young boy, Heihachi threw him from a cliff, and scarred him for life. To save his own life, Kazuya offered his soul to the Devil, becoming bent on killing his father. Despite this, he loved his grandfather Jinpachi in his young days."
- Snake: "And after the first Iron Fist King Tournament?"
- Otacon: "Kazuya became more powerful than his father, and recruited some of the most powerful fighters to his cause. He was overthrown by Heihachi, but saved by G Corporation."
- Snake: "He sat out the King of Iron Fist Tournament 3, letting his boy Jin Kazama do the work."
- Otacon: "After thwarting an attack on G Corporation labs, Kazuya came back to the fighting in the 4th King of Iron Fist Tournament. He won the semi finals by default, and after winning the tournament, confronted Jin in Hon-maru. After the battle, Kazuya and Heihachi were left to fight of Jack-4 robots, but the son escaped on his own."
- Snake: "There was an incident during the 5th tournament."
- Otacon: "Yeah, and that division of G Corporation paid, with their lives."
- Snake: "I read a newspaper article reading "G Corporation head becomes unknown being out of hell and smashes Mishima Zaibatsu robot". And on one of the paragraphs, I saw that the witness, Xiaoyu was in despair."
- Otacon: "Watch yourself, Snake. Don't let the Devil overtake you."
Note: "G Corporation head becomes unknown being out of hell and smashes Mishima Zaibatsu robot" refers to him being Devil Kazuya and smashing Alisa to near pieces.

In Kazuya's case, the line is "Who knew I'd be coming to a kiddie party?". Likewise, he and Heihachi are also the only ones to have their Kyoto Castle entry laugh recycled for the Tourney series; in Kazuya's case, as his first victory quote.
- Furthermore, both Kazuya and Heihachi received their very first original quote thanks to a preschool television character; in Kazuya's case, Ruby Biggle from Kidsongs.
- The SFX used when Kazuya entered Kyoto Castle is reused in Super Smash Bros. Tourney for the On-Screen Appearances of Banjo, Susan & Mary, Min, Mindy, Thanos, Rooney Doodle, Chai Xianghua, Yan Leixia, Doomsday, Legolas, Elrond, Kiheiji, Tenten, Sajin, Dry Bones, Curtis, fellow Tekken universe character Steve Fox, Laura, Sakura Haruno, Yachiru, Solomon Grundy, Captain America, Magneto, Pyrrha.

It is also used in both games when a Crate, a Rolling Crate, or a Barrel is broken open and as they reveal their items.
