Miyamoto Usagi (2003 TV series)

Miyamoto Usagi was a recurring crossover character in the 2003 series. Usagi, several years prior to the series, was invited to compete in the Battle Nexus Tournament. While carrying water one night, he witnessed the current Battle Nexus Champion, Splinter, coming under attack by Drako (whom Splinter had beaten earlier) and a gang of shadowy assassins. Usagi quickly jumped to his aid until the Ultimate Daimyo intervened and banished Drako for his treacherous attack.

An unspecified number of years later, Usagi and his friend Gennosuke returned to compete in the Tournament. In the Hall of Champions, Usagi witnessed Leonardo, who was attending the Tournament along with his brothers for the first time, come under attack by the same assassins he had encountered years ago and came to his aid. During this fight, Usagi and Leo formed a friendship which would endure even when they were pitted against each other in the arena. Right in the middle of their match, however, the Ultimate Ninja decided to set his plans to claim the Battle Nexus for his own and take revenge on Leonardo in motion and poisoned Leo with a blowgun dart.

Even though initially distrusted by Donatello, Usagi maintained his calm and eventually ended up fighting side by side with Don against the shadow assassins, who were trying to kill both the weakened Leonardo and the Daimyo. He subsequently joined the Turtles, Splinter and Traximus in their attempt to stop the Ultimate Ninja and Drako from getting hold of the Daimyo's War Staff, and after the crisis was resolved, he and the Turtles, especially Leonardo, parted as friends.

Later, he visited the Turtles in New York. Leonardo was transported to Usagi's world by the Ultimate Ninja/Drako and asked Usagi for help.
