I am absolutely certain that the Leader’s distinctive cranium underwent a significant redesign in rehoots, and early character designs support this.

Brave New World brings back one of the Marvel Cinematic Universe’s most underutilized villains after a 16-year absence. Samuel Sterns (Tim Blake Nelson) was last seen in 2008’s The Incredible Hulk when exposure to Bruce Banner’s blood triggered his transformation.

Actor Tim Blake Nelson's wonderfully goofy take on the Leader helps forgive a lot of the clunkier parts of Brave New World. But the character would have been so much more impressive had it followed the model set by the groundbreaking comic book series The Immortal Hulk.
