Ok, here me out, deaged Batman, but while the bats are looking for a cure to save their father/mentor, the league is put in charge of baby sitting 14 years worth of sass Bruce.:
After a mission, everyone in tye watchtower is doing a debrief of their injuries.
"I got stabbed with something, but i assume it was poison that didnt work facts to my intolerance." Batman said calmly, pointing at a little neddle wound on his his arm.
Suddenly, POOF, where the dark knight once stood, a boy with smoky liner now in his place.
"WHO is that-??" Flash was cut off by the boy.
"How could you not? My names Bruce Wayne. Y'know, billionare orphan prodige?" The put both hands on his hips.
"Wait...Bruce Wayne, as in BATMAN?!" Green Lantern couldnt believe it
"Whos Batman? No. Just Bruce Wayne."
Wonder Woman could not comprehend how cute he looked.
Flash took so many pictures to blackmail batsy with later.
Superman could not handle a teenager. He got sassed out.
