Top 5 MCU Fan theories in 2021

Updated: Jun 25

The Marvel Cinematic Universe is currently knee-deep in phase 4 of its plotlines. Let us check out the MCU fan theories currently doing the rounds in 2021:


Neither Sam nor Bucky is the next Captain America


The upcoming " The Falcon and the Winter Soldier" series seemingly put the Falcon in the shoes of Captain America. This is was sort of confirmed at the end of "Avengers: Endgame" where an aged Cap passes on The Shield to the falcon played by Anthony Mackie. But as we fans know from experience, the MCU rarely makes things simple.

Remember the time the Infinity war trailer showed the hulk charging into action against an unseen force? This turned out to be a misleading clue as it was Banner that fought the "space dogs" in the hulkbuster suit. There was also the trailer for "Thor 3: Ragnarok" where Thor was shown with two fully functional eyes, wielding his lightning powers.

One easter egg in the trailer of "The Falcon and the Winter Soldier" shows the falcon running onto a football field, high-fiving a person dressed comically as Cap. This clue along with sources in the industry have hinted at Wyatt Russell taking on the mantle of Captain America. Russell has shown his action chops in the 2018 movie "Overlord," making him a sensible choice for the role (apart from him looking exceptionally caucasian I guess!)
