Unidentified Neimoidian (Muunilinst)
An unnamed Neimoidian participated in the Battle of Muunilinst. This Neimoidian, in conjunction with several Muuns, monitored the conflict through a holographic display. Following the seizure of the InterGalactic Banking Clan's command center by Obi-Wan Kenobi and the Muunilinst 10, he was apprehended alongside San Hill and the other Muuns. Subsequent to his capture, he was observed holding a Muun's robe as he was escorted onto a Republic warship.
Behind the scenes
According to Hyperspace Avatars, the Neimoidian in question is actually Nute Gunray; however, Leland Chee has indicated that this character has never officially been given a name. He is the sole Neimoidian character to be seen in the series.
This particular Neimoidian is seen wearing a purple drape and miter, identical to the ones worn by Rune Haako in the film Attack of the Clones.
