Zandarreo, who was also referred to as the Jetsam of Lasan, was a gladiator of the Lasat species. He found himself as one of the enslaved fighters within the Grakkus Arena located on Nar Shaddaa. As part of a preliminary promotional announcement by Toren to the Hutt Grakkus, Zandarreo was planned to battle the Wookiee Wrollanppf in a battle to the death, with the fighters being advertised as "One-Eye Volant the Eviscerator" and "Zandarreo, Jetsam of Lasan." A version of the poster advertising Zandarreo's potential fight with Wrollanppf was featured within Maz Kanata's Smuggler's Guide while Toren possessed it.
The character Zandarreo was initially referenced within Star Wars: Smuggler's Guide, a reference book released in 2018, and written by Daniel Wallace.
