Sir Christus, Finnish guitarist
Sir Christus (born Jukka Kristian Mikkonen; April 10, 1978 – December 7, 2017) was a Finnish guitarist, best known as the former rhythm guitarist of the glam rock band Negative. His father was Arwo Mikkonen, guitarist of the Finnish rock band Popeda. His father died in 1986, leaving eight-year-old Christus and his four-year-old brother Matthau, without a father figure in their life.

On Negative's single "Fading Yourself" (March 14, 2007), Sir Christus did vocals for a bonus track: "Lost in America" (originally by Alice Cooper). Negative has never performed this song live. Christus performed this song live, with the band Private Line, on November 28, 2007.
