Isaac McDougal

Issac McDougal was an alchemist with drug addictions and other legal problems until he was approached by the scientist Solf J. Kimblee to pose as the The Explosion Alchemist, the idealized perfect terrorist. Taking responsibility for the widespread accidents caused by Kimblee's experiments, the Explosion Alchemist persona convinced people that he was in command of the infamous terrorist organization known as the Ten Rings, eventually becoming the most feared terrorist in the West. He was captured by Edward Elric and put in prison, where he became something of a celebrity.
