The Fastest Hero
The Flash is one of the most famous superheroes of DC Comics. If it corresponds to several different characters, the most known is Barry Allen. He works for the Central City Crime Lab when he is struck by lightning while handling chemicals (in later versions, he is injured in an accident near a particle gas pedal). In any case, this gave him an uncommon speed that could exceed the speed of sound and, by vibrating his molecules very quickly, the ability to pass through matter.
