The epic climax to the quartet of Avengers movies arrives in UK cinemas on April 25 and many midnight screenings are already sold out.
But if you've been too busy for an Avengers catch-up before the biggest film release of 2019, fear not, as we've got you covered with an essential recap on all you need to know going into Avengers: Endgame.
Of course, Avengers: Infinity War is the most recent addition in the Avengers series but we're going to start our recap with the first, 2012's The Avengers (or Avengers: Assemble).
The Avengers (Avengers: Assemble)
2012's The Avengers is the culmination of four years of work in the MCU.
Everything from 2008's Iron Man to 2011's Captain America has lead to this moment. At the time, this was the biggest cinematic crossover ever made.
Humanity is facing destruction as Loki, acting on behalf of Thanos this time, is busy planning for a full-scale alien invasion of Earth.
Standing in his way are the first generation of Earth's mightiest heroes, The Avengers. The team number just six (Iron Man, Captain America, Thor, Hulk, Black Widow and Hawkeye) and after spending the film squabbling, they team up to finally put an end to Loki's fiendish schemes.
Before long, The Avengers are back in action and we join our intrepid team of heroes on a mission to rid the world of Hydra, a secret terrorist organisation born out of the Nazis during World War II.
In an effort to prevent future conflicts before they occur, Tony Stark and Bruce Banner begin to work on their Ultron concept, to create a defensive shield around Earth so that humanity will be protected even after The Avengers disassemble.
However, their plan backfires spectacularly when the Ultron AI takes on a will of its own and vows to wipe out humanity in order to save the planet.
Once again, The Avengers overcome the odds to tackle this internal threat, created by one of their own.
For the most part, The Avengers team remains the same from their first outing. But as the film draws to a close, several new members are added to the team including Vision, Scarlett Witch, Falcon and War Machine.
While the third Captain America film may not necessarily be an Avengers film by name, the inclusion of so many of the Avengers means we're including it here.
After two movies of fairly harmonious team building, The Avengers are faced with their biggest threat to date that leaves the team scattered and divided.
Following the events of Age of Ultron, the Sokovia accords are enforced, meaning The Avengers will not have the same freedom to operate in the way they have been doing.
This tears the group apart and leads to an almighty superhero showdown, the effects of which are still felt as Thanos begins his invasion of Earth.
Infinity War, the most colossal film in the MCU to date, completely changed the game for The Avengers and has totally reshaped the MCU going forwards.
The Avengers are still scattered to the four winds when Thanos's invasion of Earth begins.
Thor spends the film on the hunt for a new weapon to replace his hammer as he realises the true threat posed by Thanos. His journey sees him team up with The Guardians of the Galaxy who have added to their own ranks over two films of their own.
Meanwhile, Iron Man and two new additions to the Avengers, Spider-Man and Doctor Strange, stow away aboard one of Thanos's ship in order to take the fight to the great Titan himself.
And finally, Captain America and the rest of the Avengers team, including new face Black Panther, are on the ground and fending off Thanos's huge army.
Despite all of their best efforts and an axe to Thanos's chest, nothing The Avengers nor Guardians of the Galaxy does is able to stop Thanos from unleashing his catastrophic plan and wiping out half of all life in the universe.
A quick recap of each film in the MCU can be seen in Marvel's latest and final trailer for Avengers: Endgame which can be viewed below.
And that is where we stand ahead of Avengers: Endgame, ladies and gentlemen.
Just how excited are you for this next instalment in the MCU?
