Major spoiler warning!!!Edit
The King of Demon Rulers
The King of demon Rulers went through several transformations as he absorbed more and more negative energy. In is first form he is looks just like the other demon rulers only more menancing. This form has twice the power of omega shenron only without the elemental powers. During his battle with Majin Buu and Cell, he took energy from his remaining minions and transformed into a larger form will large claws and spikes sticking out of the body. After completetly absorbing all of Janemba's energy, he grew larger and took on armored form, and gained janemba's reality warping powers, as well has his weakness to insults. After he shed the armor it revealed a hideous mutated form underneath. This form then escaped to hell, where he then took energy from the prizoners, and grew into an even larger more hidious form. He reached an ultimate state after he swallowed omega shenron, gaining his energy and elemental powers, and growing bigger again, now the size of a sky scraper. He weekness in this form is that he become very slow in this form and has very poor control over his energy, his power contantly leeks out of his body. Nova shenron managed to escape from inside of his body since his energy couldn't be absorbed. The rest of the dragonballs were torn out of his body one by one, removing his elemental powers and causing him to shrink. His shrunken form end up being just as dangerous with more speed and better control. This shrunken form was distroyed by a spirit bomb. However, he still was able to survive, as the spirit bomb only distroyed his outer shell. The final form underneath turned out to be even more dangers because even though he had lost most of his power, including the janemba abiltities, he still had a huge amount of power left, and was no longer inhibited by his huge size and poor control. This last form looks similar to his first form, only with five times as much energy.
