Yeeeeeees. Yesyes. All of this. Janet is honestly thriving. Like- look at her son go. She's so proud. She's MOST proud when the title King of Gotham outstrips even Son of the Drake for him. Look at her boy! Earning his own name! Outside of herself!!!! She's so proud of him, and she makes absolutely sure he knows it. Tim loves when she visits, and is deeply proud of how he's used what she taught him, even if neither of them expected it to end up like this.
I am ABSOLUTELY gonna run with an AU idea of what-if the whole family was underworld at one point, because you are RIGHT they'd be the most terrifying thing the underworld had ever seen, each of them so dangerous on their own, but the Wayne family being so much more terrifying because they work together and genuinely trust each other.
ANYWAY back to this. I really like Lord of the Narrows for Jason- it keeps him from claiming any names that would be in use elsewhere and stepping on toes. DICK. Oh, oh, Dick my beloved. SO. I DO have thoughts on him for this AU. Because we know, canonically, he was going to go out and fight crime on his own to literally kill the man who set his parents up to fall right? Dick has absolutely tripped into Underworld stuff entirely by mistake as a kid, and dug into it. It was an option after all, for how to deal with his parents' killer. He'd never told Bruce, but he absolutely looked into it. And he picks up some of the unspoken rules.
Adding in what his circus really was, and the travels he had as a kid? He knows more than most civilians, if not as much as one actively involved would, especially as a kid. So he knows enough to go to the Continental as a kid, and he may talk to some people Bruce would be DEEPLY upset to know he was talking to. Not about business of course- even HE knows that rule- but just...to learn more.
Perhaps makes some "friends" while he's there.
But Dick with his anger issues and everything else? Surprisingly educated despite never actively stepping foot into the underworld. It's part of why he gets along so well with Damian at the start. He knows enough. He's not an active member, but he's used the underworld connections. Usually when his rage is being an...issue. Bruce would flip if he knew his sunshine child used fighting rings and bets to vent. (Does Dick introduce Jason to them for the same reason? yes absolutely. Does Jason lose his mind a little bit to realize his big brother regularly bets and fights in fight rings to handle his temper behind the Bat's back? ABSOLUTELY.)
I love Damian watching the changes ripple out, and see such a FAMILIAR look in his brother's eyes, when he talks about changing things and...he can't help but take a second look then. Of course he has to- Timothy is so...passionate about this. And he's not really happy about it at first, but he can see immediately where their "Class" of underworld differs, because Tim doesn't have that understanding on noble-underworld that comes with being born to it. He's blunt when he points out the first mistakes- the ones that will have every noble coming for his head, and what he might change to achieve what he wants. As time progresses, and he sees the changes rippling through the working class of underworld, and ripple further up into the noble ranks, he starts believing it's needed, believing in what Tim is doing, which is where he starts sitting down with him to really brainstorm it out and plan.
I adore the idea of a Table arc where it really is just Tim surviving over and over again, the Batfam coming together with him, proving Cobblepot SO SO right. He's glad these people never- bar a few- stepped deep into the underworld at all. It's terrifying to see them step up to the Table's best and win. Consistently. LET TIM BE AN ABSOLUTE BADASS. This could ALSO be where Gotham starts building the network of homeless and such it becomes known for, as Jason uses old street kid connections to keep an eye out for threats to his brother.
Gotham, from the very beginning, establishes itself as ODD because the city knows outsiders, and they work together for each other against them. Even regular citizens will do it, because Gothamites stick together. You go through so many villain attacks together, and you dont even think about it anymore. Gotham is a crime haven and hive, but her people are strong and while they might fight, when the chips are down, they ban together in disasters, or against outsiders that cause trouble.
They're not Rouge Level after all. (And yes, Gothamites do roll their eyes at underworld people vs some of their big name villains)
But YES in the end, Tim establishes himself as the King of Gotham. Gothamites snort, because as the son (and did you hear? some whisper he was confirmed to be Bruce's son by blood) of Bruce Wayne, and well known face with various charities and forces for the city, of course he is. Bruce held the crown before him, why wouldnt it be one of his kids to take it? Underworld know it with a different emphasis, and whisper about the working class (if of a higher skill set then most) ascended to noble, that FOUGHT THE TABLE for them and cemented roles and rules for them-
They call him a "People's King" among themselves. THEIR King, a regard earned with his changes and rehauling. Regard kept because he stood his ground, and holds to it. He keeps his word, and enforces his laws and rules, and the city falls in behind them. How could they not?
Janet is near busting with pride. Bruce is absolutely pegged for having all these shady contacts, but...ask the right people and they talk about the connections his parents had. How honestly it's not too surprising he has them, just that it took this long for him to be caught using them. He supports the Bats dont you know? It's not surprising he'd use those connections for them. Probably for their gear the people whisper. He's still a darling of Gotham- look how well he uses his money and connections for their city! He's not too bad.
GOTHAM AS A RETIREMENT HOT SPOT FOR THE UNDERWORLD IS FANTASTIC. Tim sees it as a check and balance too- he holds to the rules, makes sure they're followed, and these people that retire here, they all WANT these rules to stay in place. They work with him to keep the city covered.
Lots of them fold the street kids under wing. They don't take Jason's people, but they act as check points and sort of safety nets while they're running around. Tim hires a lot into Wayne-adjacent jobs in various places. He makes a point to give them a chance and crack down hard and fast if he catches any of them touching things they shouldn't with the money or paperwork or other workers or anything, so they learn fast. Most dont even try it. It's the Son of the Drake who arranged it for them- they're not FOOLS. They've seen him tug on the flow of Gotham and redirect the entire city to his whim, they wouldn't dare.
