Bruce Banner has one rule: smash everything. But what if his walkie-talkie was unbreakable? Imagine the Hulk holding a massive, indestructible walkie-talkie while smashing through a Hydra base: “Banner out!”
This walkie-talkie would be made of vibranium (of course) and could withstand even the Hulk’s rage-induced tantrums. It would also have a “calm down” button that plays soothing classical music to help Bruce regain control. Genius.
