Smart Hulk’s Endgame Injury Can Be Fixed By A Forgotten MCU Character
The injury Smart Hulk suffered from Avengers: Endgame being miraculously fixed in Phase 4 can be explained if Marvel Studios decides to bring back one character from Avengers: Age of Ultron. While the rest of the surviving heroes spent their time differently on the heels of Thanos' snap in Avengers: Infinity War, Bruce Banner used his figuring out a way to combine the best of his two personas. This resulted in the introduction of Smart Hulk in the MCU who has the raw strength of the original green-rage monster and consciousness of his human alter-ego.
