Marvel's future Disney+ show "What If...?" besides providing an animated look into alternate scenarios for canon characters, could also imagine a multiverse without "Smart Hulk"-- a combination of Green and Grey Hulk.
Smart Hulk has incredible strength that's coupled with high intelligence: Bruce Banner's ideal Hulk.
People who watched the original TV show in the '70s and '80s grew to love that Hulk.
But that hybrid Jekyll and Hyde character that fans saw in Avengers: Endgame might not be seen in "What If...?" the new Marvel series being planned for Disney + that's based on the original comic from the '70s.
