Clash Of The Titans.

Legion felt big and very powerful. It was not an illusion. Their body was expanding quickly. They grew to be kilometers tall. They had to stop growing for fear of exploding. Even then, they were more than 1,000 kilometers tall. 

The world trembled around them as they moved. Space was quaking and vibrating at a frequency higher than its normal range of operation. This is what happens when there is no longer a fundamental difference between one Supreme Power and ten Supreme Powers. 

The light side of the void universe couldn't contain them again. The vibration of the world around them was just the surface effect of the law matrix tearing apart. They were too big and too powerful for the law matrix to hold them up. This caused the world of manifestation around them to fragment and disappear.
