Ziro the Hutt was a major antagonist in the film Star Wars: The Clone Wars. Ziro is Jabba the Hutt's uncle.
During the Clone Wars, Ziro ordered the murder of fellow Black Sun vigos, though his IG-86 assassin droid, KRONOS-327, failed in this task. Shortly after KRONOS-327 reported his failure, Ziro was approached by Senator Padmé Amidala at his palace on Coruscant, when she tried to reopen communications with the Hutts, as they believed that the Jedi had abducted Jabba's son, Rotta.
In the film, it was revealed he had Jabba's son kidnapped under the orders of Count Dooku. When Padme Amidala arrives for a negotiation, he sents her to his dungeon. When the Republic found out, they arrested him for this and trying to kill Padme who they rescue and put him in jail removing Ziro from the Galactic Senate. While in jail he managed to hire Aurra Sing to kill Padne Amidala the woman who was responsible for catching him but Aurra failed in the end. After Sing was captured, Jedi Padawan Ahsoka Tano and Jedi Master Anakin Skywalker visited Ziro in his cell. He admitted to the assassination attempt, which extended his sentence in the facility. Some time later, Ziro was broken out of jail by Cad Bane, but Sy Snootles shot him the heart with a blaster eventually, once she had manipulated him into getting her a hidden holopad for the Hutt Council.
Around this time, the Jedi Counci sent Jedi Masters Obi-Wan Kenobi and Quinlan Vos to bring Ziro to justice. Their investigation naturally led them to the Hutt Council's stronghold on Nal Hutta, where Vos used his natural psychometry abilities to track Ziro to his mother's house, who then directed them to Teth. However, by the time the Jedi and Cad Bane arrived, Ziro was already dead.
