Seems like somebody got inspiration from Frontier: An Okoto Space Roleplay.
Name: Saur Millis
Age: 198 (please correct me if this is too old, I couldn't find anything listing the average lifespan of a Muun)
Personality: Saur was considered a very loving person, and his position lent him grand opportunity to lend to the less fortunate, asking nothing in return. After the empire took over, his moods began to shift. He is very delicate in everything he does, sometimes making him appear weak and clumsy. However, he is extremely malicious and despicable towards the empire, sometimes winding himself into a blinding fit of rage in which he tends to make up words to express his fury.
Appearance: Saur is the standard height of a Muun, with wider shoulders and larger arms/legs thanks to his training. His lips have been shredded, exposing his teeth and gums, giving him the appearance of a malformed zombie. To recover his speaking ability, he has installed a tiny voicebox on his throat which adds the necessary sounds normally provided by the lips, feeling information through his nerves and running on his body heat, making him sound like both an organic and an inorganic being.
Habits or Quirks: Likes to tap his fingertips together incessantly, even while standing. He occasionally scratches around his facial scars. Refers to the Imperial Empire as the "New Separatists". Will sometimes say something as a joke only he understands and laughs wildly, overloading his vocal box for a few seconds.
Weapons: Phrik-plated gloves are on his hands, attached to heat-resistant fibers. He also wields a westar-34 blaster pistol and carries a thin-bladed vibroblade dagger.
Abilities: He is versed in martial arts, and is exceptionally strong. He is an experienced electrician, and knows separatist machinery like the back of his hand. He is almost entirely incapable of flying a ship, however, and usually gets about on-foot whenever he has to travel on-land.
Bio: Part of the InterGalactic Banking Clan, Saur was well-known within republic hierarchy and the Jedi Council as a traitor to the separatists and a "Mr. Money Bags". He occasionally slipped out info whenever he was sure it was safe about the next move of the Separatists, although towards the end of the war the Banking Clan had to heighten security measures and the source died off almost entirely.
Then the war was lost. Saur lost most of his resources as the Bank sucked money together to rebuild, and moved off into semi-retirement, still keeping his image as a public figure of sorts. He became a technician and served on a few cargo vessels. After his fifth trip, however, his home was visited by the newly constructed Imperial Empire. Hoping to be greeted as a friend and ally to the Separatist's destruction, he was attacked by the visitors who had orders to destroy this "Separatist Remnant".
Eventually one of the soldiers, realizing that, with his combat abilities, weaponry, and phrik gloves, they were no match for him, blew himself up, and the blast not only severely damaged Saur's home, the shrapnel scarred him irreparably.
Using his resources that he had left, he had the voice box made, his home demolished, and fled his home, fearing the wrath of the "New Separatists" as he refers to them as. Stranded on Nixus, he has immediately started cementing himself as a criminal mastermind, in an attempt to eventually drive the Imperials off the planet. He does not know about the Rebel Alliance... Yet.
