Much to Marvel's annoyance, the trailer of Avengers Infinity War was leaked soon after its preview at Comic Con San Diego. But due to copyright issues, the footage was later taken down from the internet.

The leaked footage has finally made its way to YouTube, giving an eyeful to fans about the fates of Iron Man, Captain America, Thor and Spider Man.

Fans of the Marvel Cinematic Universe have already seen their favorite Avengers battling and thrashing every alien invasion that has threatened the earth. This time, however, they are not fighting an alien, but will be facing Thanos, the Mad Titan.

The trailer shows superheroes flexing their muscles to fight and defeat the greatest threat on earth. Tony Stark and Captain America must put a united front before the greatest enemy they have ever encountered but the war may not be as easy as the previous ones.

The leaked trailer for Avengers 3 begins with the audience cheering to the voice over of Mantis who says: "We are arriving." Star Lord, the captain of his spaceship Milano asks his Guardians to stay prepared for what comes next. He says: "Alright Guardians, don't forget this might be dangerous so let put on our mean face."

To the surprise of Gamora, Drax and Rocket Raccoon, the body of Thor falls and hits the windshield of the spaceship. They bring his unconscious body inside Milano. He later wakes up thanks to Mantis] and is surprised to see his space saviors. "Something is very wrong," the Norse God speculates as he arrives somewhere in the galaxy along with the Star Lord and his team of cosmic Avengers.

Thanos will be the main villain in Avengers Infinity War Marvel

Cut to Scarlet Witch who appears to be dodging some powerful force on Earth while Spider Man senses danger. In another scene, Loki emerges on the screen to offer the Tesseract to someone gigantic (many believe it may be Thanos). Tony Stark appears to give a little Ted talk as he encourages his team on attacking the greatest super villain. "We have an advantage. He is coming to us. So that's what we will use."

Marvel's Avengers Infinity War will hit the theaters on 4 May 2018.
