First Duel on Kamino

The First Duel of Kamino resulted years after the Invasion of Naboo. The Jedi Council learned of unathorized cloning activities on Kamino and sent Anakin Skywalker, who had recently returned from Ansion with Qui-Gon Jinn and Obi-Wan Kenobi, was sent along with R2-D2 to investigate and inform the council on the status.

Arrival on Kamino
Anakin arrived on Kamino and was greeted by Taun We and Prime Minister Lama Su. R2-D2 waited outside to make repairs to the ship. Anakin learned that the clone army had been created actually for the Republic. The late Jedi Master Sifo-Dyas had placed order for the army ten years ago and was killed after that. Anakin explored the facility and learned of the cloning process. The bounty hunter Jango Fett had been the source of the clones. Anakin went to visit the hunter and learned that Fett knew nothing about Sifo-Dyas and had been recruited by Neimoidians on Bogden. Anakin then left to report to the council. The holographic image played to the entire council stating what Anakin had learned. Yoda ordered Anakin to arrest Jango Fett and return him to Coruscant.

Duel
After arriving on the platforms of where Jango's ship the Slave I was, Jango tried to kill both Anakin and R2-D2. Anakin proved the bounty hunter that he had the upper hand and arrested him.

Aftermath
Anakin flew his Jedi Starfighter back. Even though the fighter had room for one, Anakin had to sit on top of Jango in order for the two, along with R2-D2, to return to the Jedi Temple. Mace Windu then interrogated Jango Fett on who hired him, while Anakin and R2-D2 secretly headed to Tatooine because Anakin wanted to find his mother.
