A male Neimoidian from the planet Cato Neimoidia was one of the aides to Baron Merillion Tarko of the Galactic Empire at the Tarko-se Arena in the city of Tarko-se, which was located on the purse world. He had red eyes, green skin, no hair and wore a large head-dress and decorative clothing while at the arena.
In 1 BBY, the Jedi General Rahm Kota, who had been captured after a failed raid on the planet, was forced to fight a horde of rabid beasts and gladiators in the Tarko-se Arena for the pleasure of the local Moff, Baron Merillion Tarko. After watching the Jedi Master defeat a massiff and yet another executioner, the disappointed Baron ordered the aide to give it another try by releasing the Corellian slice hounds into the arena.
When Starkiller, a clone of the late Galen Marek, entered the arena to relieve an exhausted General Kota, the Neimoidian aide was ordered by the enraged Baron Tarko to open the gate of the massive creature known as the Gorog, ignoring his attendant's misgivings over their ability to control the beast. The Neimoidian reluctantly complied with Tarko's order.
This Neimoidian aide first appeared in Sean Williams' novel The Force Unleashed II, published on October 10, 2010. He appeared a second time in the LucasArts video game Star Wars: The Force Unleashed II, released on October 26 of the same year. He was voiced by David W. Collins.
