Mr. Universe

Mr. Universe was a reclusive techno-geek. He lived (apparently) alone on a moon with his love-bot "wife", Lenore. He had a great affinity for data and was capable of intercepting nearly any transmission or recording in the system. He was seen stepping on a cloth-wrapped glass (as well as wearing a yarmulke) in a video clip of his wedding, indicating that he may be Jewish.
He was killed by the Operative as part of a trap the Operative set to capture the crew, but had set plans in motion for Malcolm Reynolds to broadcast a report from an Alliance scientist that revealed the origins of the Reavers.
