By the year 252 BBY, hueches perpetrated an attack against a Colicoid nest, targeting its queen, along with Jinnix and their drone-mate. During the assault, the drone-mate was unsuccessful in safeguarding the queen, and subsequently, they presented Jinnix with an explanation for their failure, which Jinnix perceived as mere justifications. In response, Jinnix decapitated the drone-mate and consumed their ganglia. Later, while serving as a Storm within the Nihil marauders, Jinnix remembered the hueches' attack on their nest when their Strike Towl offered a reason for disobeying a command.
The High Republic: Tempest Runner, an audio drama from 2021 authored by Cavan Scott and released as part of Phase I of the Star Wars: The High Republic multimedia project, featured mentions of hueches in flashbacks. The proper spelling of their name was officially verified in 2022 with the publication of the audio drama's script. Within the Star Wars Legends continuity, a hueche was depicted as a predator of the Colicoid, appearing in a hologram within Millennium Falcon, a novel penned by James Luceno in 2008.
