Marvel fans are once again caught up in the age-old question of who wins in a fight: The Avengers or the X-Men?The debate was sparked on social media after a Twitter user posted an image of Fox's original leather-glad X-Men team and the Marvel Cinematic Universe's Avengers as seen in Age of Ultron with the prompt "Which team is clearing." Since the original post, the argument has opened up to include every iteration of the teams, ranging from movies to comic books.Related: Jonathan Hickman Was Accidentally Responsible For Xavier's Death In AvX

While both The Avengers and The X-Men have fans avidly defending either side, the general consensus is leaning towards Marvel's team of powerful mutants coming out on top.

Some fans have brought up the fact that the X-men and the Avengers have actually gone to war before. The 2012 crossover comic book series Avengers vs. X-Men (often abbreviated to AvX) pitted the two super teams against one another when the Phoenix Force returns to Earth, looking for Hope Summers. Upon discovering this, Captain America attempts to secure Hope but is stopped by Scott Summers, who believes her to be the mutant messiah. Scott believes Hope to be a messiah, capable of saving the mutant-kind.
