10 Best One-Off Characters In The Marvel Cinematic Universe

10. Pietro Maximoff/Quicksilver

Despite being a staple of the Avengers in the comics for many years, Pietro Maximoff, aka Quicksilver, only fully appears in Avengers: Age of Ultron. He and his twin sister Wanda join forces with Ultron after gaining powers from experimentation with an Infinity Stone (changed from their mutant origins in the comics).

However, after learning of Ultron's true intentions, they join forces with the Avengers. Unfortunately, Pietro dies in the film's climax in order to save Hawkeye's life, cutting his time in the MCU short.

Although the MCU doesn't do Quicksilver as well as the X-Men films, which give the character three great scenes in which we see the world from his perspective: slowed down with a fun song in the background, Aaron Taylor Johnson's version of the character has his charm. His cocky attitude and rivalry with Hawkeye are fun to watch, and he has some great moments, such as trying to grab Thor's hammer mid flight and his "Get off your asses" scene in Sokovia.

Although Quicksilver probably shouldn't have been just a one-off character, he makes for a good, if temporary, addition to the Avengers.
