This is a role that will likely continue with the followingAvengers : Secret Warsand may even begin originally withFantastic Four : First Steps .

Dying As The Hero AND Becoming The Villain

Robert Downey Jr. come back as Doctor Doom is a remarkable case of dying as the hero but ALSO living long enough to become the baddie . It ’s a twist on a conception that originally came from Christopher Nolan’sThe Dark Knight , which many have assign to this surprising Marvel molding . As Robert Downey Jr. himself say after removing his Doctor Doom mask on phase at SDCC:“New mask , same project " , the same task being his return to the MCU to serve lead the franchise onward ( though this clip as a major villain rather than a hero ) .

to boot , the fact thatRDJ ’s Iron Man was the one who finally defeated ThanosinEndgamemakes this casting all the more intriguing and super poetic . The MCU ’s Thanos replacement is the very same actor who played the hero who defeated the unrestrained Titan himself . It ’s all very cyclical , one that makes Doctor Doom even more exciting as RDJ is likely to inherit the same kind of overarch villain role that Thanos had in the Infinity Saga .
