As Bruce Wayne, he can buy Marvel from Disney and discontinue the production of Hulk’s comics.
Loved the time Spider-Man defeated the Hulk by telling a joke, which made him revert back to Bruce Banner.
Batman can’t do that, though.
Maybe Batman could use calm, reasoned debate and bore the Hulk into reverting.
Pays for Bruce Banner to have therapy and anger management to work through his PTSD and anger issues.
Hulk Repellent.
More seriously: prep time, massive amounts of sedatives, or a phone call to Superman to get him to deal with it instead.
See also, any time Batman has had to deal with similar DC villains: Doomsday, Darkseid, Bane, etc.
Shoot him with a dart containing a massive dose of propranolol. Adrenaline cannot bind in Bruce Banner’s body, making him unable to trigger the transition to Hulk. Batman beats him up easily.
Well, movie Banner tried to kill himself with a gun and the Hulk spit it out so I don’t think a dart would have an effect. Unless the release of those chemicals and its spread is faster than the speed of a bullet then it’s probably useless.
Comics Hulk is a different story and depends on how he’s written because Hawkeye has killed the Hulk with a special arrow in Civil War II.
