Nos quadrinhos
O site da Marvel afirma:
Quicksilver possessed superhuman speed, and could travel on foot at speeds exceeding the speed of sound for hundreds of miles before tiring; he could "fly" for short distances by flapping his arms or "vibrating" his legs; he could also use his speed to create cyclones, dodge machine gun and laser fire, and run up walls and across water.
No entanto, seus poderes são amplificados mais tarde.
Following the loss of his mutant nature, Quicksilver exposed himself to the Terrigen Mists, resulting in him now possessing the power to vibrate his atoms so quickly he travels forward in time. His molecular speed that he generates displaces him out of the mainstream time/space so that he is able to propel himself into the future. He can leap from thirty seconds to up to twelve days, and remain for several minutes to several hours before being recalled to his present time once his body tires, or he can return at will before his time is up. As he returns from his trip, he returns the exact moment he left so as to appear that he has been gone for half a nano-second. He is able to bring inorganic objects from the future back to his correct time, although it has yet been shown what would happen if he attempted to bring organic objects with him.
Nos filmes X-Men da Fox
O site oficial do filme site oficial simplesmente lista sua velocidade máxima como "mais rápida que a velocidade do som" .
No universo cinematográfico da Marvel
Infelizmente, nenhuma informação concreta sobre a velocidade máxima do Quicksilver foi divulgada até o momento. Durante o decorrer do filme, vemos o Quicksilver ultrapassando o Mjolnir e as flechas, bem como alterando a trajetória da flecha no meio do vôo. Isso não é necessariamente indicativo dos limites de suas habilidades. Mesmo a novela júnior descreve apenas sua velocidade como "mais rápida que um trem-bala" e "mais rápida que um jato".
