[DC] What are the craziest feats the Flash can pull off without taking a step?
gpt
Vibration.

He basically has enough vibration-based powers to make a complete extra powerset which itself is quite good. He can create heat through friction or wreck machinery with simple force. He can somehow vibrate his face in such a way that people see him normally, yet photographs of him are blurred. He can phase through solid objects, making him potentially very lethal even to strong superheroes. The phasing effect can make him invisible or make the thing he passes through explode. He can also vibrate large objects, like vehicles, and make them briefly intangible too.

Basically, while the Flash is vibrating, comic-book physics and even basic common sense are temporarily demoted to being as irrelevant as real physics.
