A male Neimoidian, originating from the planet of Cato Neimoidia, served as one of the aides to Baron Merillion Tarko of the Galactic Empire. He was stationed at the Tarko-se Arena in the city of Tarko-se, situated on the purse world. This individual possessed red eyes, green skin, and lacked hair. While present at the arena, he was distinguished by a substantial head-dress and ornate attire.
Rahm Kota, a Jedi General who had been captured following a failed raid on Cato Neimoidia, was compelled to engage in combat against a throng of savage creatures and gladiators within the Tarko-se Arena in 1 BBY. This spectacle was arranged for the amusement of the local Moff, Baron Merillion Tarko. After observing the Jedi Master triumph over a massiff and another executioner, the disappointed Baron instructed the aide to escalate the challenge by unleashing Corellian slice hounds into the arena.
When Starkiller, a clone derived from the late Galen Marek, entered the arena to provide relief to the weary General Kota, the enraged Baron Tarko commanded the Neimoidian aide to unlock the gate of the enormous creature known as the Gorog. This order was given despite the attendant's reservations regarding their capacity to maintain control over the beast. The Neimoidian, albeit reluctantly, followed Tarko's directive.
This Neimoidian aide made his debut in Sean Williams' novelization, The Force Unleashed II, which was released on October 10, 2010. He subsequently reappeared in the LucasArts video game, Star Wars: The Force Unleashed II, which was launched on October 26 of that same year. David W. Collins provided the character's voice.
