>>149262792Anon is right. Adults need diapers not for pee problems, but for actual medical problems. You had a switchblade open your lower intestine to the subway? No shame in a diaper, you almost died. Then there's the rest of the Gotham villains problems. Do you think that Joker gas gets coughed out? No, it goes from lungs to bloodstream, to organs, so the kidney and liver will have to filter it. How many people would get gassed by Joker gas annually? That's a lasting mental and physical effect. No driving heavy machinery, etc.
"You ever get that feeling that you don't know if you're awake or still dreaming?"
"It's called mescaline."
Now add habitual coffee drinkers to that, and the ones sober enough to realize what that wetness is are going to admit they need diapers.
I wonder what would happen if Baby Dahl got a dose of the Man Bat serum, in an attempt to grow, or to stay with Killer Crock? Would she be small and cute, or would she be a small pointy teeth demon girl, or would she actually get to grow a taller body for as long as the serum is active?
