one punch man

A character with spiky white hair stands at the bottom of a dark crater, then the scene cuts to a figure in a black and silver suit standing on a road, followed by a close-up of a red eye, then the character in the black suit lunges forward and strikes the white-haired character, sending him flying backward into a cloud of dust, and finally the black-suited character is shown holding a glowing blue sword above the white-haired character who is on the ground.
