Batman headcanon that once the Batkids kind of start thinking of settling down and having/adopting kids, they come to a realization. If they all get kids around the same time, they’ll be about the same age and once they get older, only one of them can be that generations Robin. So begins the great feud.
It becomes a scramble on who can have a kid first and name the kid Robin/Robyn to cement the title (It’s Dick in the end, Jay is the first to have kids but his are adopted and, thus, have names already). They all suck up massively to Bruce. “look how accomplished my son is, wouldn’t you say he’s sidekick material??” “Bruce look how fast my girl solved that mystery! It looks like you have another detective to train.” And through all this Bruce is just sweating. He loves all his Batgrandbabies, how can he possibly choose one to be his partner?
So the time comes when all the kids are trained and ready, specializing in their chosen areas and looking up at Grandpa with proud, nervous faces. They can still be vigilantes if they aren’t chosen, but being Robin is something special. Bruce can’t stand their sad faces, so that’s how an older Batman takes to the streets with like eight goddamn Robins trailing behind them all decked out in varying costumes of red, yellow, green and black. He explains he’s old, he could use the extra help out there, really he couldn’t say no to any of those precious kids. So what started out as a lone quest many, many years ago has become a bright menagerie of bright smiles and whooshing capes and loving whispers of ‘grandpa’ when no one else can hear. Everyone is happy expect probably the rogues and I’m sure Child Protection Services isn’t pleased either.
