Garank, a Gamorrean male and a Nihil marauder, served as a crew member on the Gaze Electric, the flagship commanded by Eye of the Nihil Marchion Ro. Back in 232 BBY, he, along with Nihil members Baheeoo and Ordo, engaged in a frantic race aboard the Gaze Electric. Their mission: to deliver Ro's urgent order to alter their course towards the planet Trymant IV. Driven by the desire to be the first to reach the bridge, Garank resorted to throwing Ordo into Baheeoo, causing them to fall. He then made his escape. However, his actions were short-lived, as Garank met his death by being eaten by a Bogaranth ridden to the bridge by the other two Nihil.
During the High Republic Era, Garank, a Gamorrean Nihil marauder, was a member of the Gaze Electric's crew. This vessel served as the flagship for Eye of the Nihil Marchion Ro, and he was one of the few Nihil given access. In 232 BBY, Ro masterminded a collision involving the Byne Guild freighter Legacy Run and an obstacle, resulting in the Great Hyperspace Disaster. This event triggered Emergences, where debris from hyperspace materialized and struck various celestial objects across the galaxy. After learning that one such Emergence was poised to threaten several locations within the Trymant system, Ro made the decision to travel to the planet Trymant IV. Zagyar, a Storm, initially attempted to communicate the command to the bridge. However, upon discovering that the comms on the Gaze Electric were malfunctioning, he instead dispatched Nihil members Baheeoo, Garank, and Ordo with instructions to immediately notify the ship's captain about the revised plan.

Driven by Zaygar's threat of ejection through an airlock for the last Nihil to arrive, the trio sprinted from the rear of the Gaze Electric toward the bridge, unsure of whether they could reach it within Ro's allotted time. Garank gestured to the side and grunted in Gamorrean, which confused Baheeoo due to the Gigoran's lack of understanding of the language. When Baheeoo turned to see what Garank was pointing at, the Gamorrean seized Ordo and hurled the Talpini's body into the Gigoran, causing both to fall. Garank then fled, leaving the pair behind with the intention of being the first to reach the Gaze Electric's bridge.
Baheeoo and Ordo opted for a dangerous shortcut through the pen containing the ship's Bogaranths, bloodthirsty creatures known for devouring anything in their path. While Garank continued his sprint toward the bridge, the other Nihil pair mounted a Bogaranth and rode it to the same destination. Upon their arrival, Baheeoo called out after spotting Garank, only for their Bogaranth to then eat the Gamorrean. The Gigoran then amended their statement to refer to the now-deceased Garank in the past tense, while Ordo lamented the painful nature of being eaten. Ultimately, the pair succeeded in informing the Gaze Electric's captain to alter course for Trymant IV, though they were informed shortly thereafter that the comms had just been repaired.
Garank displayed a strong desire to outpace his colleagues when he learned that only the first Nihil to reach the bridge would avoid being thrown out of an airlock. He was even willing to throw Ordo into Baheeoo to leave them in a heap on the floor, thereby gaining a head start. The Gamorrean possessed blue eyes, green skin, and muscular arms. Garank communicated using the Gamorrean language.
While serving aboard the Gaze Electric, Garank wore a purple armored chestpiece, a brown belt with a large, circular silver buckle, and black fur shorts. They also sported a black bandolier, black wrist cuffs, strappy black sandals, and a black cap featuring spikes and openings for the Gamorrean's ears.

Garank's first appearance was in "Tales of Villainy: The Gaze Electric," a supporting comic story featured in the sixth issue of the 2020 Star Wars Adventures anthology comic series. Daniel José Older wrote the story, Nick Brokenshire provided the illustrations, and IDW Publishing released it on July 7, 2021.
Brokenshire aimed to emulate the visual style of Star Wars comics from the 1970s and 1980s when designing the color palette for the comic story. He noted that limited color technology at the time necessitated panels that visually popped. As such, the Gaze Electric and its crew, including Garank, were colored in this style, though the artist clarified that the colors may not necessarily reflect reality.
