Behold, Marvel fans!

The first teaser trailer for the highly anticipated superhero team-up film Avengers: Infinity War is here, and it's something you definitely don't want to miss.

See how Marvel fans reacted to another major trailer with BET Breaks, above.

Proving to be one of the largest Marvel productions to date, Infinity War sees the biggest power players from your favorite team-themed superhero flicks — The Avengers, The Guardians of the Galaxy, and pretty much every other Marvel superhero introduced within the last decade — join forces.

The insanely large group of heroes is set to face off against Thanos, the villain of all villains that Marvel's been teasing since the closing credits from the first Avengers film back in 2012.
