Prompt: It worked?!
Danny is in Gotham for college, and during finals month the Joker goes on a spree. After the Joker breaks out of Arkham for the THIRD time Danny in a fit of sleep deprived pique does a bit of research, breaks into Arkham, and swaps prisoner transfers so that the Joker is taken to a prison out of state.
It’s only after finals are over, and he has slept for two days, that he calls Tucker to check on his half brained plan, to find out it worked? Somehow it worked. The Joker is now at a different prison where he has no corrupted guards etc to help him breakout and is now stuck there.
The bats only find this out when their paranoia of “why hasn’t the Joker broken out yet?” kicks in.
I like to think this is one of those things Bruce had been trying to do, legitimately of course, for years. But somewhere between Gotham's corruption, well timed breakouts, and no other prison really wanting to deal with the Joker anyway; every prior attempt to transfer him fell through.
By swapping paperwork, Danny quite accidentally managed to cut through all those problems. The transfer was already happening before anyone knew anything about it. Therefore, it didn't need some corrupt officials to sign off on it; the receiving prison didn't have to be strong armed into taking him; and probably most crucially, Joker had no time to breakout between learning about his transfer and said transfer happening.
I also think it'd be good if Danny didn't even send him somewhere super high security (ie Belle Reve). Those transfer are probably rarer and come with too much fanfare. Instead, Danny sent him to some random prison in, like, Wisconsin* or something. Which, on top of being narratively funnier, actually works out better because it's so far removed from Joker's normal network of goons and corruption. He either has to wait for his normal helpers to get there, or try to build all that influence back from the ground up while being stifled by being under such close watch and having to fight his way to the top of whatever established hierarchy there already is in the new place (again, alone, without his own established network bolstering him).
Either way it's gonna take time. Months and years even. And, once they know about it, time is very useful to the Bats for cleaning house before Joker inevitably ends up back in Gotham. The more of the Joker's network they can root out and clean up, the harder it'll be for him to breakout again later.
Plus, the longer this random prison can hold him, it helps build very strong evidence for Bruce's legitimate attempts to get Joker transferred. No more other institutions arguing they don't have the means to secure someone like the Joker. Security isn't the issue; Exhibit A, this prison did it for years no issue.
*Danny, leaving a voicemail at 3am during his stressed out sleep deprived brilliance: Hey Frootloop! You've got plenty of influence in Wisconsin. Do something to help keep Joker in his new home and I'll go to 3 Packer's games with you every year he's there. Kay thanks, bye! Whoever invented statistics is evil. Evil, evil, bad box of Raisin Bran evil. Where'd my calculator escape to? *Several more seconds of rustling and muttering before Danny actually remembers to hang up.*
Vlad has one of the Ghost Vultures assigned specifically to Joker to keep him in prison so he can make Danny go to more Packers games with him.
The corrupt millionaire using his evil minions for good lol.
Even better, he's transferred under his actual name, not his villain moniker.
It is what causes the Minnesota prison to accept the guy, because they don't realise who he is until he is already there.
He tries to break out more forcefully during a prison fight only for some vampire wannabe looking guy-who's flying? Is he a super? There's more of them??-shows up and slams him back into the cell and locks him in. All he hears is muttering of:
"gotta keep him in there... Badger going to games... Prove I'm a good dad to those blasted Ancients..." before he's gone and the guards are putting him in solitary as punishment and dedicated guards.
This is the start of a vlad redemption arc, and the start of his 'hero' arc, but it's just to keep the joker in prison, whenever he takes a step out of the prison, the minions call for him.
Danny goes to the games because it was part of the deal, and while he does not hate it, he sees that vlad does his best to ensure nothing ruins the game, especially other villains, as to make sure "the little badger can't run off if he has no excuses" so he furthers his hero arc to also stop any villains who appear in the city or town the Packers game is before the game starts.
Vlad has been offered to join some hero teams, he turns them down, saying he doesn't have the time to devote to the philanthropy lifestyle of heroes. Much to anyone's confusion since one year he had made lex Luther turn himself in when the packers game was in metropolis.
Vlad knows about his ties in Cadmus, he knows Luther is no good, and he so happened to have a folder of incriminating evidence against him. Much to Luther's confusion.
