Kyo Kusanagi (Earth-430)

Kyo Kusanagi is a cocky warrior, leader of the Kusanagi Clan and son of the legendary Saisyu Kusanagi. One of the first members of Raiden's Defenders of the Realm, Ryo, along his allies, rose up to become the greatest protectors of Earthrealm.

Early Life
In 1994, Kyo was a cocky high school student and the heir of the Kusanagi Clan. Kyo could wield flames naturally at the age of 15, and soon surpassed his father Saisyu's fighting abilities. Destined to fight the Orochi, he became the clan leader. He eventually met a girl named Yuki, who became his girlfriend.

Shortly after the completion of his training, Kyo competed in a preliminary tournament in Japan to determine the members of the country's representative team in the King of Iron Fist Tournament, hosted by the local the Mishima Zaibatsu, and organized by it's CEO Heihachi Mishima. He defeated Goro Daimon and Benimaru Nikaido to become the leader of the Japan Team. Afterwards, the three became teammates and good friends. Sometime after this, Kyo was pestered by fellow high school student, Shingo Yabuki. Shingo begged Kyo to teach him how to create flames. Though annoyed by Shingo's persistence, Kyo partially agreed to mentor him as a means of gaining free meals.

First King of Iron Fist Tournament
On the Tournament, Kyo was pitted against Heishiro Mitsurugi, a warrior with no team but him own, in the Semifinals, but was sparred, as Mitsurugi wanted nothing with the Tournament, instead seeking information about Soul Edge, which Mishima had. Raiden noticed Kyo's fighting prowess, and believing he and his clan could be potential allies for events who could come, said he would be a welcome addition to his allies, the Defenders of the Realm. Kyo arrogantly avoided the proposition, but after finding out he and his team was foiled by Nina to loose the tournament so Mishima's forces could win, he and Team Japan accepted without thinking twice.

Second King of Iron Fist Tournament
Before the Second King of Iron Fist Tournament, Kyo and Team Japan (Daimon and Kikaido) attended the ceremony on the White Lotus Temple after Ryu's victory over Heihachi Mishima, now the champion of the King of Iron Fist Tournament. When Shadaloo, the enemies of the Mishima Zaibatsu, commanded by Sagat and a horde of Tarkatans led by Baraka and Shang Tsung invaded the Temple, Kyo, along with Jax, partnered-up to defeat the invaders, alongside all of the Defenders of the Realm. When they finished, Raiden revealed that Earth's warriors would need to undertake a new King of Iron Fist Tournament, now being hosted by Shao Kahn and M. Bison on Outworld, if their realm was to remain safe, as per Elder Gods counsel. Kyo, alongside all of the warriors, was transported to Raiden to the enemy realm.

Post-Invasion
After the Third King of Iron Fist Tournament Tournament and Shao Kahn's Invasion, he ended up joining with his rival Iori Yagami and Chizuru to fight Orochi as destined. In 1999, Kyo was attacked and taken by the NESTS syndicate. NESTS used his DNA to create various "clones" of Kyo. K' was also infused with Kyo's DNA at this time. He awoke one day and managed break out of captivity. He forcibly questioned a few of his captors and tried to investigate what happened to him, but wasn't able to learn much.
