During the Clone Wars, Robonino was an associate of known Trandoshan bounty hunter, Bossk, sometime during an unknown period of time during the war, when their ship fell apart and was destroyed, but they survived and were found by the Black Hole Pirates. The two joined the pirates and Robonino fit in well with the team and worked well with them while Bossk found himself alienated and an outcast amongst the pirate gang. Robonino was later found by Cad Bane and was convinced to join his gang and took part in a mission alongside Aurra Sing and Shahan Alama to capture the bounty hunter Davtokk.
Robonino was part of a group of bounty hunters that took the entire Senate hostage to force them into freeing the criminal Ziro the Hutt. He was a pivotal part of lead bounty hunter Cad Bane's plan, as he sent the entire building into lockdown and trapped the senators inside. Later, he left with the rest of the group.
Robonino, along with Chata Hyoki, was hired by Count Dooku to intimidate various senators to try to stop a vote on a Senate bill. Dooku later instructed them to assassinate Senator Padmé Amidala, but they failed and were arrested.
- His bio in the Star Wars: The Clone Wars Character Encyclopedia says, "Judge Robonino by his size and you'll soon regret it!".
