Mr. Universe (portrayed by David Krumholtz) was a minor character in Joss Whedon's sci-fi film Serenity. He was a reclusive techno-geek who operated his own pirate broadwave station from which he could intercept just about any transmission throughout the 'verse. His station was located on a solitary moon surrounded by an ionic gas cloud where he lived and worked alone, save for the company of his love-bot "wife", Lenore.
After Malcolm Reynolds and the crew of Serenity discovered the origins of the Reavers on the planet Miranda, they sent the recording they had found to Mr. Universe, telling him to transmit it across the 'verse so that everyone would know what the Alliance had done. However, the Operative had reached Mr. Universe first, offering to pay him handsomely for selling out Mal and his crew. But when Mr. Universe demanded payment, the Operative instead stabbed him with his sword before returning to his ship. As the eccentric hacker bled to death, he crawled over to his bed where his robot wife sat, laying his head in her lap as he died.
When Mal later arrived at the complex, he found Mr. Universe dead, but Lenore had recorded his murder and saved a copy of the recording Mal had sent. While Mr. Universe's main console had been destroyed, Lenore revealed that there was a secondary terminal in the lower levels of the building, meaning that Mal still had the chance of transmitting the recording and exposing the Alliance's illicit experiment.
