Demoniac were a New Zealand heavy metal band,[1] formed in Wellington in 1993 by singer and bass player Lindsay Dawson, guitarist Sam Totman and Drummer Steve Francis.

Dawson and Totman adopted the stage names "Behemoth" and "Heimdall" respectively, and were later joined by unknown keyboardist The Magus and Head Like a Hole drummer Mark Hamill as "Adramolech".

While Dawson had played bass in all of the band's recordings, South African bassist Diccon Harper (ex-Voice of Destruction) was hired to allow him extra freedom during live performances.

Other Demoniac members have been involved in DragonForce's releases: Harper played bass on their album Valley of the Damned, and Dawson and original drummer Steve Francis performed backing vocals on Inhuman Rampage and Extreme Power Metal respectively.

In 2012, Prepare for War was re-released with new artwork and the previously unreleased track "Throne of Fire", performed by Dawson and Steve Francis with Bulletbelt guitarist Ross Mallon.
