Tasty Revenge

Tenma's regal features turned serious, the white of his eyes turning entirely black and he suddenly turned from a charming figure to one that was demonic.

His long black hair turned to black smoke, and the light shining on the surface of the planet dimmed until it appeared as if the world was in twilight.

The darkness he had conjured when he arrived had clasped the hundreds of thousands of spikes shot by the Ouroboros Serpents and with a squeeze of his hand, he crushed them to dust. The sound made from crushing those spikes was apocalyptic, and a slow grin began to grow on Tenma's face.

He pointed his second hand at the angered creatures, whose spikes were already halfway regrowing and he snapped his fingers, and a wave of darkness drawn from the boundless immensity of space and shrunken to hundreds of thousands of miles wide swept towards the serpents and slammed into them with enough force to crush a hundred worlds.
