Superhuman Speed – The ability to move, run, fly, react, think, and sense at speeds much faster than a normal human. Those with this ability also have accelerated brain activity which allows them to process sensory information so fast that everything seems to be moving in slow motion while the user moves at normal speed. Examples of characters with this power include Quicksilver (Marvel) and the Flash (DC). Superhuman Speed is also known as Enhanced Speed, Extreme Speed, High-Speed, Hyper Speed, Immense Speed, Supernatural Speed and Super Speed.
In the series DC vs. Marvel, the Flash beat Quicksilver decisively.
