- "Oh, Ziro the Hutt, Master of the Hutt Clan on Seven Systems, I am sorry, your Highness."
- ―KRONOS-327 addresses Ziro by his formal title
Ziro was a Hutt crime lord, who controlled the Hutt Clan in seven systems during the Clone Wars. He conspired with Count Dooku to kidnap his nephew Jabba's son, Rotta, but the plot was foiled and he was imprisoned. Before going to prison, Ziro imprisoned Galactic Senator Padmé Amidala after she arrived to discuss the Hutt's affiliation with the Sith Lord Count Dooku, however, C-3PO contacted Clone Troopers, who came and rescued Amidala. Ziro was then arrested and sent to prison. Some time later, Ziro hired the bounty hunter Aurra Sing to assassinate Senator Amidala as revenge for his imprisonment. After the assassination attempt on Alderaan was foiled by Ahsoka Tano, Sing was taken into custody and Ziro's plan was revealed. His plan ruined, Ziro threatens Tano, saying “You have no idea what I'm capable of!". Fearing Ziro would confess many of the Hutt Clan's dealings to the Republic, the other Hutts paid Cad Bane to break him out, so they could imprison him under their watch. Cad Bane broke Ziro out of prison by taking a group of Senators hostage, which coincidentally Amidala was a part of. Bane used the hostages as leverage for getting a pardon disk from Supreme Chancellor Palpatine, which he passed through the Twi'Lek Senator Orn Free Taa. Ziro was then freed from the Republic prison, and was taken to the Hutts for punishment. Jabba paid Ziro's lover Sy Snootles to break him out once more, so he could lead them to the location of the Hutt Council records he hid on Teth before killing him.
At some point, Ziro was born to Mama the Hutt and had a brother named Ebor. He then had an affair with Sy Snootles, one of his nephew Jabba's dancers. However, Ziro ended the affair and went to Coruscant. There, he operated a nightclub.
During the Clone Wars, Ziro made a deal with Separatist leader, Count Dooku; Dooku's assassin, Asajj Ventress would kidnap his nephew Jabba's son, Rotta. However, Ziro then learned from Naboo Senator Padmé Amidala that the Jedi had rescued Jabba's son. Fearing that his role would be discovered, contacted Dooku, informing of Amidala's investigation. Dooku assured Ziro that Jabba believed him about the Jedi killing his son. Knowing Jabba would execute the Jedi responsible, Dooku assured Ziro that he would become master of all the Hutt Clans when the Jedi would bring Jabba down. Ziro was then ordered by Dooku to eliminate Amidala if she continued investigating.
Ziro and his IG-86 sentinel droids then found Amidala. When Dooku realized that it was Amidala, he told Ziro that his allies would pay him for delivering Amidala to him. Ziro, agreeing to the deal, had Amidala placed in his dungeon and thanked Dooku for the profitable alliance. However, Ziro then learned that Amidala had contacted her Protocol droid, C-3PO for help. Thus, he decided to execute Amidala, knowing his powerful friends in the Republic Senate would protect him. Ziro and droids were then attacked by Commander Fox and his detachment of the Coruscant Guard that 3PO called. Ziro was then held at gunpoint by Amidala.
