Ketch was a male Weequay individual who was a frequent customer at Cid's Parlor, a cantina located on the planet Ord Mantell. He was most often observed in the company of Bolo, who was an Ithorian.
Ketch, a male Weequay, made his home on Ord Mantell. Back in 19 BBY, he would regularly visit Cid's Parlor alongside his close companion Bolo. Their activities there included arguing, consuming alcoholic beverages, and engaging in games of dejarik. His initial encounter with the Bad Batch happened when the clone troopers were in search of Cid.
Sometime after the Bad Batch had completed an assignment for Cid, Ketch and Bolo noticed Omega practicing with a Zygerrian energy bow and began placing wagers on whether or not she would successfully hit her target. Omega became irritated by their mocking laughter, but Echo advised her to disregard them. Shortly thereafter, Cid arrived and promptly dismissed them from the area.
Following the Batch's return from a mission to recover a lizard from the Rhokai gang, Bolo and Ketch were engaged in a game of dejarik at the bar. After Wrecker, Omega, and several other patrons had departed, and Hunter, Tech, and Echo were meeting with Cid in her office, Bolo and Ketch found themselves alone in the bar with one other individual, Captain Rex in disguise. Bolo took exception to Rex occupying his usual seat and demanded that he move, a request that Rex conspicuously ignored as he continued to sip his drink. When Ketch pointed out to his friend that the man was ignoring them, Bolo reiterated his demand more forcefully. The situation rapidly escalated, and Rex compelled the two to retreat by discharging two warning shots from one of his blaster pistols. Cid, Hunter, Echo, and Tech emerged from her office in response to the commotion and witnessed Bolo and Ketch fleeing the bar, with Bolo yelling at Ketch to get out of his way.
Later, Roland Durand had seized control of Cid's Parlor, prompting Cid to devise a plan to reclaim it. Ketch and Bolo were assigned a specific role in this plan: they were tasked with creating a diversion for Durand. Ketch walked past him, deliberately scattering grains of Mantell Mix behind him, with the intention of luring Roland's pet Ruby to follow them. Soon after, Durand realized that Ruby was missing and went in search of her, providing Cid and the Bad Batch with the opportunity to enter the office and steal his spice. The duo made their escape when Durand discovered them.
