Marvel's What If will feature a large ensemble cast.

A series of leaked images, taken from footage screened at D23, have increased interest in  Marvel’s What If? series.

The animated series, set to air on the Disney+ streaming service, will tell a series of stories set in alternate versions of the Marvel Cinematic Universe.

Here’s everything we know about Marvel’s What If? so far.

The stories will be overseen by Uatu The Watcher

What If? will introduce the character of Uatu The Watcher, voiced by Jeffrey Wright. Uatu will serve as the series’ narrator.

In Marvel lore, it is the job of the Watchers to observe and record the goings on in the multiverse. Though hugely powerful, they are not permitted to intervene in the affairs of those they watch. Uatu refuses to join the battle against Thanos in the ‘Infinity Gauntlet’ story line, despite Adam Warlock pleading him to do so.

The Watchers have been seen in the MCU once before, during Stan Lee’s cameo in Guardians Of The Galaxy Vol.2. It is unknown if any of these Watchers were Uatu.

The first episode will feature a universe in which Peggy  Carter was the recipient of the Super Soldier serum.

Rather than becoming the ‘Captain America’ we all know and love, super-soldier Peggy will be known as Captain Carter in the series. Her shield is also slightly different, featuring a Union Jack in the centre.

Steve Rogers is not forgotten in this universe. While he does not receive the serum, Steve becomes the operator of a special mech-suit designed by Howard Stark, effectively making him this reality’s first Iron Man.

The romance between Steve and his beloved Peggy also appears to be intact. In one of the leaked images, Captain Carter appears to be hitching a ride on Steve’s back as he flies in his suit.

T’Challa will appear as an alternate Star-Lord

T’Challa will be very different in ‘What If?’

The D23 footage featured an alternate version of Guardians Of The Galaxy’s opening sequence, with a very different Star-Lord than the one we are used to. In this reality, Star-Lord is none other than T’Challa, the main universe’s Black Panther.

It will be interesting to see the exact ‘What If?’ scenario this universe spawns from. Whatever it is, it raises a lot of questions about the fate of other characters in this reality.

With T’Challa in space, who will take up the mantle of Black Panther?

And if T’Challa is Star-Lord, what happened to Peter Quill?

We will see a zombified Captain America.

When the What If? logo was revealed at San Diego Comic Con, some keen-eyed fans spotted what looked like a zombie version of Captain America hidden within it. This prompted speculation that we might see a zombie Cap in the series.

The D23 footage and subsequent leaked images confirmed this, with the Winter Soldier seen doing battle with an undead Steve Rogers. Whether this is an isolated incident within that episode’s universe, or a hint at a full ‘Marvel Zombies’ adaptation, is unknown.

Marvel’s What If? will feature an all-star line-up of MCU cast members.

Hayley Atwell will reprise her role as Peggy in ‘What If?’

The cast list for What If? reads as a ‘who’s who’ of the Marvel Cinematic Universe’s biggest names.

In the first episode, Hayley Atwell once again reprises her role as Agent/Captain Peggy Carter, along with Dominic Cooper as Howard Stark.

Later episodes will have the majority of the Thor cast appear, along with Mark Ruffalo as The Hulk, Paul Rudd as Ant-Man, and Samuel L. Jackson as Nick Fury, to name only a few.

We’ll have to wait until What If? premieres on Disney+ in 2021 to see what the multiverse has in store for our favourite characters.
