(@HailMother) April 23, 2021Back in January, a Deadline report dropped a bombshell after it hinted at a possible MCU return for Chris Evans in a similar vein to what Robert Downey Jr. did in Spider-Man: Homecoming.With rampant rumors of Chris Evans' pending return to the MCU running wild online, the uncertainty surrounding his potential involvement has only intensified with each passing day.If Chris Evans was indeed set to return as Steve Rogers, Deadline also claims that it would reportedly be in a project separate from that of Captain America 4.If that is going to be the case, then it leaves the door wide open for a whole range of exciting new possibilities:Could fans witness Chris Evans return as "Evil Captain America," where he plays an undercover HYDRA agent in an exclusive "Secret Empire" comic storyline adaptation?Perhaps he could return in some form in Doctor Strange in The Multiverse of Madness?Or could he actually be on the moon, assisting Nick Fury on a secret base/spaceship off-planet?Steve Rogers as an undercover HYDRA agent in "Secret Empire" (Image via Marvel)Despite Marvel President Kevin Feige and Chris Evans denying the possibility of a Steve Rogers return, fans continue to enthusiastically speculate on the possibility online:CAPTAIN AMERICA 4 FEAT.

It is time for Sam Wilson to shine now.But when it comes to the ever-expensive MCU world of multiverses and diverging timelines, anything is possible.
