15 Most Heart-Wrenching Moments In MCU History

2. Avengers Assemble - Avengers: Endgame

The fight between Steve, Bucky and Tony is one of the most touching and shattering fight scenes. This isn't Batman and Superman fighting for no reason. It's not even Thor and Hulk fighting. This is two best friends fighting, because one of them hid the fact that they knew who killed the other's mom.

And it's the end of the Avengers. And this is the beginning.

The last time we saw all of the Avengers together was in the airport, fighting each other. But then, when Captain America, shield broken, rises to fight Thanos and his army, literally blocking out the sun, Thor fallen, Tony broken, Sam Wilson's voice breaks through Steve's helmet.

"On your left."

And then a portal emerges. And another, and another.

Spider-Man, Black Panther, Okoye, Shuri, Star-Lord, Drax the Destroyer, War Machine, Ant-Man, Howard the Duck, Rocket Racoon, Groot, Nebula, Gamora, Doctor Strange, The Wasp, Valkyrie, Rescue, The Hulk, The Ravagers, Scarlet Witch, Captain Marvel, Winter Soldier, Falcon., Hawkeye, Tony Stark, Thor, the Asgardians, Mantis, Wong, Nick Fury and Maria Hill - all are there to take part in the fight of their lives.

With Captain America, wielding Mjolnir, shouting, "Avengers, assemble!" It's what the MCU was made for.
