10 Marvel Cinematic Universe Easter Eggs That Led Nowhere
4. The Leader's Transformation
Marvel Studios seems to have gone to great lengths to make it look like The Incredible Hulk never happened, and that includes ignoring most of the sequel setups and Easter eggs it contained.
One of them is Samuel Sterns's transformation into the supervillain known as The Leader, which kicked off in the movie when he was exposed to Bruce Banner's gamma-infected blood.
Similar to Tony Stark's post-credits cameo, the Leader teaser makes no sense if you only follow the movies. Marvel tied up this loose end in the digital comic series Fury's Big Week, which revealed that Black Widow later arrived on the scene, subdued the mutating doctor and handed him over to SHIELD.
Once again, the entire thing felt like a massive rug sweep. Is everyone supposed to pretend there wasn't going to be an Incredible Hulk 2 with him as the villain?
