There are at least two artists under the name Dethonator. 1: Dethonator is a metal band from Great Britain. Sometimes described as melodic thrash, or old school, but the band prefers simply the title of metal. Nothing more nothing less. Dethonator was formed in Leicestershire during the summer of 2002 under the name of Kaleb, a band name they were known by until the summer of 2009 when the name change was spurred on by a series of external factors.
