I desperately need a crack treated seriously fic of Batman pulling out more and more specific and random items from his belt. It starts off innocuous with, like, a snack for Flash and just goes from there. Next thing you know he's pulling out a geode with some ancient water trapped within and everyone is like why and where and how. And Batman is just this one time in Gotham-
I had a fic idea a while back anon where Jason and Bruce both have to unload their pockets/belts and it's just piles and piles of knives, wrapped candies, half a human finger (Jason), a suspicious amount of reinforced zip ties (Bruce), weapons that don't look like weapons (both), a full day's worth of MREs, and like 60 million random little screws or bullets from the bottom of both of their utility belts.
Neither of them, as you mentioned, see any problem with what they're carrying.
