In this theory discussion, two potential scenarios and four reasons for the possible return of Tony Stark's Iron Man to the Marvel Cinematic Universe (MCU) are explored. However, despite these possibilities, there are reasons to believe that such a return might not be advisable.

Hosted by Swapnil, the episode delves into the intriguing world of superhero theories, ranging from sensible to eccentric. The episode begins by acknowledging Iron Man's pivotal role in the MCU, particularly the iconic portrayal by Robert Downey Jr. The character's arc, from a self-centered billionaire to a selfless hero, is highlighted, and his sacrifice in "Avengers: Endgame" is praised as a fitting conclusion to his journey.

The podcast delves into two main scenarios for Iron Man's potential return:

1. Morgan Stark's Legacy: Instead of Robert Downey Jr. reprising his role, the podcast suggests that Iron Man's legacy could continue through his daughter, Morgan Stark. This approach is seen as a way to honor Iron Man's character while avoiding potential narrative pitfalls.

2. Original Avengers in Secret Wars: The theory speculates that a possible return of Tony Stark could be part of a larger MCU event, like "Secret Wars," where the original Avengers, including Iron Man, might make a comeback to combat new threats.

Four key reasons are outlined for Iron Man's potential return:

1. Multiverse Consequences: Iron Man's actions in "Endgame" inadvertently lead to the creation of a multiverse, which could warrant his involvement in resolving the chaos that ensues.

2. Genius vs. Genius: Iron Man's unparalleled intelligence could be crucial in countering Kang the Conqueror, a formidable adversary with advanced technology.

3. Enhancing Secret Wars: Iron Man's return in an event like "Secret Wars" could provide an exhilarating moment for fans and invigorate the franchise.

4. Fan Attraction: Iron Man's reappearance could boost audience engagement and interest, potentially offsetting recent declines in MCU reception.

Despite these compelling scenarios and reasons, the podcast argues against a full-fledged return of Iron Man. The character's completed arc, legacy, and the need for the MCU to develop new heroes, especially heroines like Ironheart and Shuri, are emphasized. Iron Man's potential return is seen as a risk that could dilute the impact of his previous exit and impede the growth of fresh characters.

In conclusion, while the possibility of Iron Man's return is explored through various angles, the podcast advocates for a cautious approach, suggesting that if any return were to happen, it should be limited to a cameo. This way, Iron Man's legacy can be respected, new characters can shine, and the MCU can continue to evolve. The host invites listeners to engage further by following them on Twitter (@SFYTSwapnil).
