his backstory this is the one known as Malice he was a genius when it came to engineering but one day he decided to mix elements with his work and created four creatures known as the blights of malice he hoped it would help him and the makuta as he thought his creations could do things like fight,build etc but before he could make any more and also before he hadn't told Teridax he was killed in an "accident" when researching but no one knows what happened some believe it was a toa that killed him some say he died by the hands of his own creation but at this point it has become just rumors but none the less he is dead.
