This is a picture of Dr. Omega, as he is being played by Michael Liu. Dr. Omega is the scientist/doctor on board the HSS Emmanuel (HSS: Heavenly Star Ship) and is one of the crew members of the Mission 316 cast.
Typically, Dr. Omega is described by the others as being anywhere from "slightly odd" (courtesy Ensign Alpha, as portrayed by Jessica Schultz) to "crazy" (Quincy, as played by Scott Adams) or "eccentric, but loveable, nonetheless" (Tammy, as played by Samantha Adams) and just about everything in between.
Dr. Omega dresses in almost all black (although there was one episode script where he was wearing orange - long story!), usually a turtleneck, long pants, tennis shoes and sunglasses. He never takes his sunglasses off and nor has he ever been seen by anyone without them on, leading to the conclusion of First Mate Paula that he probably has some sort of eye condition. This has not been confirmed by the doctor himself. He also wears a white lab coat most of the time.
It has also been rumored that Dr. Omega is not human, due to the fact that he does have pointed ears and several odd mannerisms.
As the actor who plays Dr. Omega, Michael Liu describes his character as "different" and says that "he does things that I would never imagine doing in real life". "Yet, he is very in control of himself and his actions," Michael said in a recent interview. "Scott is always trying to get us [myself and Samantha] to write Omega doing something completely random, but that's really not in-character for him." However, he enjoys playing the doctor and Dr. Omega will continue to be a prominent character in the Mission 316 episodes yet to come.
