Kreator

The word "Krea" in the ancient's language means "sorrow, or rage." Atosa used this word to describe the situation where those in pursuit of Ator eventually met their end. Kreator gained the wisdom of the ancients and the dark energy. It grew three times its regular size and gained monstrous strength. It would summon the other ancient weapons, Alten and Kalten, when it was caught in a dangerous situation. If you confront Kreator, you'll understand in depth about the Aakman's transformation.
