It all started when G.U.N was working on an experiment,the general who wanted to create the ultimate weapon did not succeed in the procedure as Doom was awakened,he escaped from the G.U.N military base and is now working with Black Doom and finding a way to find the Seven Emeralds without letting anyone know.......He is an immortal and can never die and as that continues,he will gain more power and become unstoppable and there will be a conclusion point to an never-ending situation where he causes suicide.
