Omega's only goals in life are to take revenge on Dr. Eggman for wasting his potential and destroy the doctor's other robots to prove himself superior. These two goals are absolute above all else in Omega's eyes. As a result, he tends to be extremely headstrong, reckless, aggressive, and destructive - decimating anything that gets in his way. Omega is fairly loyal and dependable when one is on his good side, a bit of a holdover from his original purpose as a servant, and he is not incapable of looking past differences to forge alliances                     

   Omega does have a cannon voice and that’s around what we are looking for, you must be ok with peaking robotically and having your voice filtered to sound more robotic
