Jinnix, a Colicoid Nihil Storm, served Pan Eyta within her Tempest. As a leader of one of Eyta's Tempest Storms, Jinnix orchestrated a raid to seize a glitterstim shipment located in the Abrion sector.
Once upon a time, Jinnix resided in a nest alongside his drone-mate and a queen. During a hueche raid on their nest, the drone-mate was unable to defend the queen. Upon hearing their explanations for their failure to protect the queen, Jinnix decapitated the drone-mate and consumed their ganglia.
Following an coup d'état, the Twi'lek colony planet of Aaloth started exporting stim. An informer working for Pan Eyta inside the Hutt Cartel notified the Tempest Runner about a shipment traveling along the Roon Way, not long after a prior shipment. Jinnix's Storm then confronted a cargo ship piloted by RL-18 and crewed by the Twi'lek Lourna Dee. Lourna ultimately killed him using his own spike.
Jinnix was featured in flashback sequences within the 2021 audio drama The High Republic: Tempest Runner, penned by Cavan Scott.
