Spoiler Alert! There are tons of spoilers for Avengers: Endgame, Infinity War and much of the MCU below. You’ve been warned!
With so many beloved characters crammed into Avengers: Endgame, even with a three-hour run time some were bound to get short shrift. It’s nevertheless shocking and disappointing that the Hulk, one of the most popular original Avengers and the second-longest tenured MCU hero, is almost completely absent from both Endgame and Infinity War.
Wait a second, you might say. Hulk is all over Endgame! The simple truth, however, is that the character featured in Endgame — helpfully dubbed Professor Hulk by the internet in honor of a similarly merged version from the comics — is not the Hulk at all.
