The question of who is faster - Flash or Mercury - worries all DC and Marvel comic book fans. Every lover defends his side, but in this fight of superheroes there is a winner and a loser. Those wishing to know the answer should definitely read the material.
Who is Mercury?
To find out who is faster - Mercury or Flash - you need to know general information about superheroes. The first one is the hero of the Marvel universe, which is not part of the X-Men, but often helps them. In various comics, he acts as an antagonist or protagonist. His main ability is to run incredibly fast.
In the movie X-Men: Apocalypse, the authors showed him as a guy with strange tastes in clothes, and his speed was at the level of slowing down all the time around him. Magneto is considered his father, although the guy himself does not dare to tell him about it. Mercury has a twin sister, known as the Scarlet Witch, and also has tremendous power. It is because of the ability to develop insane speed that he is compared with Flash, which has similar abilities.
Superhero Flash
Flash and Mercury from X-Men are doomed to be rivals, because the authors made these characters almost the same in terms of strength, but there is a difference. At different times, four personalities performed under the pseudonym of a DC comic book character. Each of them had the same abilities, and their fates were intertwined. Unlike Mercury, this character received his strength from a lightning strike and after that was able to develop exorbitant speeds. Flash was a member of all communities of heroes who stood guard over the order of the Earth.

He was one of the first members of the Justice League and was on the council of this group of heroes. His teammates rescued his abilities more than once, because thanks to his incredible speed he could react to the actions of the enemy. The question of who is faster - Flash or Mercury from X-Men - appeared only after the second character began to be shown in different films (Avengers, Apocalypse and others). A man in a red suit from DC comics gained his popularity long before that. This happened largely due to his charisma, constant jokes and cheerful character.
Duel
The answer to the question of who is faster - Flash or Mercury - does not require a lot of research. It is enough to compare their maximum speeds, as well as the ability to constantly use force. In the comics, Flash received such tremendous power from the lightning discharge that nothing limits it in the above two parameters. He can develop a speed that is a hundred times higher than the stream of light, and run on it indefinitely. He has no processes in his body that are responsible for fatigue, and therefore his ability has almost no flaws.

Mercury has a much worse situation in this regard. In his body, the processes responsible for fatigue are muffled, but still present. This means that he will have to stop from time to time and take a break for the sake of recovery. In this, he loses to his rival superhero. This is not all, because even if you take short-distance running, then it becomes clear who is faster - Flash or Mercury - from the speed indicator. In the comics of the Marvel Universe, it is clearly indicated that a character can only run at supersonic speed. Its limit stops at 1193 kilometers per hour. Flash has no such restrictions. That is why he is the winner of the short and long distances in this duel of superheroes.
