Gotham Rogues hate - or at least have history with - the Bat, his string of Robins and extended allies. That is known. That overgrown cosplayer and his gaggle of twerps have been knocking out goons, wrecking shipments and foiling plans since they squeezed themselves into those damn spandex costumes.
But other rogues from outside of Gotham? They better not touch their Bat or his Robins. Imagine if you will:
Lex Luthor arriving into Gotham and cornering the Bat only for Harley Quinn to show up, kneecap Luthor with her hammer, nod politely to Bats and walk off into the night like nothing happened.
Nightwing has been shot in the side, he's dragging himself to safety before Deathstroke can find him. A car pulls up, door pops open, it's Don Falcone, "get in kid".
Red Hood is caught with no bullets, empty holsters Lady Shiva closing in and he's down some alley, where a door opens and it's Two Face, jerking his head for Jason to get his ass inside.
Robin is about to get taken out by a sniper sent by the League of Assassins, the Joker drops an anvil on their nest because he's the only one who kills Robins in this city.
Dr Psycho is targetting Red Robin and Killer Croc bursts out of the sewers, snapping him up like the "fucking mosasaurus in Jurassic World" according to Tim later on.
Rogues hate the Bat and his brats but if anybody is going to take them out, it isn't going to be some hicks from Metropolis or that pile of shit they call Bludhaven.
