Diamond Sharp

From Tardis Wiki, the free Doctor Who reference

Diamond Sharp was a rock star. When he was in his sixties, he gave one last concert, a virtual reality dream concert. Unknown to the audience, his plan was to kill the audience members, blame it on the computer, and sell his story for a fortune. He was defeated by the Sixth Doctor with the help of music critic Robin Pen and an avatar of the computer. (PROSE: Sold Out)
