Demonoid is a Swedish extreme metal band that derives its influences from traditional death metal and thrash metal.
Therion guitarist Kristian Niemann previously had the desire to produce more brutal music and had made earlier attempts with his brother Johan Niemann, although none of this earlier work had appeared on any records. Fellow Therion member Christofer Johnsson had later joined the project along with Rickard Evensand who was working with Therion as a drummer at that time.
So far they have released only one album, Riders of the Apocalypse, in 2004. The album is about the Four Horsemen of the Apocalypse.
As of March 25, 2006, it was announced that Christofer Johnsson had withdrawn from Demonoid and that a replacement vocalist had been found.
