AU Where The Justice League Forms As Usual Except For One Slight Difference Where Bruce Just So Happens

AU Where the Justice League forms as usual except for one slight difference where Bruce just so happens to have been the one superheroing for the longest. (Excluding Diana, who got up to it in World War 1 and then mostly didn't while she learned about Man's World)

Bruce helps form the Justice League, ignoring all of the comments as they come to the sudden realization that Gotham's baby cryptid story is actually a man in a very intimidating armored suit who can and will break your arm if you cause problems for him. They are unaware that this is not the first team he's led, and actually he's used to teams full of mostly teenagers who also happen to be his children. This should be easier, this team is primarily adults.

He realizes rapidly that he doesn't understand these people.

His kids take bonding activities to mean learning a dozen different ways to break someones leg. That doesn't fly with these people. And that is most of Bruce's ideas, hell when he was a kid Alfred took every opportunity to get him out of his room and mostly that was with the agreement that Alfred would teach him how to defend himself. He's come by it honestly.

This team is not easier. They have more drama than when his house was actually full of kids. It's insane. He doesn't know what to do with it, usually he just sent the kids to their rooms or grounded them from patrol. That doesn't work here.

He comes to a strange crossroads. That falls apart when he forgets who he's working with and snaps at Hal with a full room of heroes that the next person to throw a punch or an insult without a reason too will be sparring with him.

A long standing rule in the batcave that worked two fold to prevent infighting between the kids and too ensure that they were well and truly trained.

It works wonders. No one says a word out of line for the rest of the debrief. Bruce becomes the unofficial mediator of the league over Clark because anytime he walked in on a fight it suddenly became 10 times more civil out of sheer terror of what he'd do to them in a sparring match.

Eventually they actually meet his kids. Well, one kid.

Half way through a mission (one of the rare ones in Gotham) the Bat comes to a complete stop at the edge of an alley. Every single league member on the team comes to a stop behind him. Slowly from the shadows of the alley a man in a red helmet stalks out to greet them.

"You don't call, you don't write"

"Red Hood."

"Don't Red Hood me! We've been worried sick!"

"I was at the cave last night."

"You didn't answer my texts B. You always answer my texts."

Somehow it ends with big and scary following them through the rest of the mission with a running commentary of how much Bats has let him down in his failure to respond in a timely manner to a text send less than an hour before he ran into them in the alley. It only ends when Red Robin shows up.

And even then it only ends because Hood can't keep himself from throwing a punch and Bruce has to snap at him that if he throws another one they're sparring when they get home.

And by god is Jason giving up the chance to punch his brothers.
