What If…? features one of the most powerful on-screen depictions of the Hulk yet, but it’s a shame that it’ll go unappreciated in an MCU project that flies under the radar. Despite being the second-ever major hero that the live-action MCU introduced, the Hulk has had a tumultuous journey throughout his past decade in the franchise. The character had one solo film with 2008’s The Incredible Hulk, where Bruce Banner was portrayed by Edward Norton. He was subsequently recast and replaced with Mark Ruffalo, who would go on to play the character from 2012’s The Avengers and onward. 45383e

Hayley Atwell's Captain Carter anecdote from Doctor Strange in the Multiverse of Madness' shoot summarizes how badly the MCU wasted the multiversal character. Hayley Atwell's original Peggy Carter variant made her debut in Captain America: The First Avenger and starred in her Agent Carter TV series before ing away in Captain America: The Winter Soldier. Atwell's Peggy returned in Avengers: Endgame to wrap up Steve and Peggy's MCU journey, but Marvel introduced a new variant in What If...?, where Captain Carter became a multiversal guardian. A different Captain Carter variant appeared in Doctor Strange in the Multiverse of Madness, where she was promptly killed by Scarlet Witch.

Since Moon Knight first appeared in the Marvel Cinematic Universe (MCU), the character has yet to make an appearance in any other live-action project, but What If...? did present a way for Oscar Isaac's character to return. Since the MCU began in 2008, one of the driving forces behind these movies has been the interconnected nature of all the heroes who appear. Just like in the comics, there are plenty of chances for heroes to team up and fight together.

Marvel Studios' What If...? series has come to an end before the Multiverse Saga show had a chance to adapt some of Marvel Comics' What If...? stories, many of which would have worked perfectly in the MCU. Spanning three seasons between 2021 and 2024, What If...? explored a variety of alternate universes across the MCU's multiverse, putting interesting spins on the classic adventures of the MCU and introducing variants of some of Marvel's most beloved characters. However, the MCU's What If...? could have done so much more.

Marvel Studios may have finally teased the answer to a seven-year-old MCU mystery inWhat If...? season 3, which could have major implications for the Ironheart series. While previous seasons of Marvel Animation's What If...? included only heroes who had already appeared in the MCU's live-action projects, What If...? season 3 marked the debut of several characters who hadn't yet appeared in the MCU. One of these new additions perfectly sets the stage for an MCU series, and could have also solved an annoying Phase 3 mystery.

Marvel Animation's What If...? series has finally redeemed the most disappointing and awkward mistake from 2019's Avengers: Endgame. The Russo brothers' Avengers: Endgame is widely regarded to be the pinnacle of the MCU, rounding off over a decade of storytelling as the penultimate movie of the Infinity Saga. However, this doesn't mean the Phase 3 crossover event wasn't without its issues, and one moment in particular has persisted as one of the most cringe-worthy moments in the MCU's history.

The MCU introduced the most powerful Iron Man suit of armor after Tony Stark's death, and that could be a bad omen for the Vision Quest series. Vision made a game-changing debut in Avengers: Age of Ultron, where he claimed the title of "Strongest Avenger" as he acquired Ultron's ultimate body and a combination of Ultron and JARVIS' consciousness. Since then, Vision's MCU appearances have depicted him as a much less powerful hero, and the original Vision died an apparently definitive death in Avengers: Infinity War.

In a Multiverse of Multi-villains, it's a competition to be crowned the Big Bad in What If...?.

In the final episode of What If...? Season 3, Uatu faces the consequences of his actions, and The Guardians of the Multiverse step up their game. Screen Rant is here to guide you through it.

In the six years since Avengers: Endgame marked Thanos' defeat, Marvel Animation's What If...? series has, time and again, proved just how weak the Mad Titan really is in the MCU, which has massively discredited the Avengers. Thanos made his mark on the MCU as the most infamous intergalactic warlord of the Infinity Saga and the adoptive father of Guardians of the Galaxy's Gamora and Nebula. While Thanos hasn't officially returned to the MCU, the Mad Titan has made frequent appearances in the Multiverse Saga, but these have just delivered insult after insult.
