Danny is the Crazy Old Man™️ of Gotham
So, the events of Danny Phantom happened decades ago
Like, Phantom Planet was one of the first instances of Superheroes in HISTORY. Early 1900's, just the Fentons were Insanely Ahead of their Time!
Danny is still a Halfa, but has allowed himself to grow old and live his best life before fully dying so he can accept his Throne in the Infinite Realms. He decides to experience Life in the fullest way possible, partying, drinking, making long lasting friendships that shape the lives of everybody he meets, all that!
Eventually, Danny's Party Life leads him to Gotham. And this place is just amazing!
It has all the comforts of Home, with so much more! He can Party! He can Fight! He can do anything he wants and nobody bats an eye, because a crazy old man getting into a fistfight in the middle of the road is just another Tuesday for Gotham!
He decides to spend the rest of his Mortal Life there. And this is still Early On in the DC Timeline, like, Batman Year 1 is happening Right Now.
He hangs around, befriends the local Homeless Population, and mostly just has the time of his Life! And he takes up the stereotypical Homeless Old Man look because why fight it? That's literally what he's going for!
He also unintentionally sets up a bunch of future events
He teaches Kid!Jason on his to steal Tires as repayment for driving off some muggers with a Baseball Bat (honestly he was looking forward to being mugged, it's a new experience after all)
He pulls Kid!Tim into an Alley after Tim gets caught out at night and gets chased by some Punks. He hides Tim behind a Dumpster and tricks the Punks into mugging him instead (Yay! He finally got mugged!)
He becomes kind of well known as the Old Man who wants to experience everything before he dies. He says as much too, not like he really has a reason to hide it. He just tells people "I want to live my life to the fullest, it don't matter if I live 10 more years or 10 more minutes, I'm gonna experience every second of it!"
He once walked into a Cloud of Fear Gas to see what it was like. Later he said it was a 6/10. "Not the worst thing I've had injected into my body!" He says with no Context.
He traded places with a Hostage during an active Crime Scene because he wanted to know what it's like.
He was once dared to take Batmans Utility Belt by another Homeless Guy as a joke, so he walked up to Batman later that night in full view of everybody else and just asked for his Belt. He gives up after a few minutes, and one guy asked "Why not fight him for it? It's an experience after all.". Danny replys "Nah, I've fought Vigilantes before. It was fun though, gotta say!"
...
This got away from me, but all this to say: Imagine the Bat Families Reaction when they find out "Crazy Old Danny" is PHANTOM. You know, THE FIRST SUPERHERO!
I imagine Constantine is having a stroll though Gotham after finishing up some business with Bruce, and just bumps into a homeless guy by accident.
Later that night:
Batman: Constantine, Why are you calling? Is it to do with the-
Constantine: Why the fuck is there a Homeless God in your City?
Batman: Wait wha-
...
Or imagine they know before Constantine meets him, and it goes instead like this
Constantine: Why the fuck is there a Homeless God in your City?!
Batman: You mean Old Man Danny? He's just a homeless guy? What do you mean?
Constantine: I swear on what's left of my Soul, that is a God.
Batman, a little shit: I don't think so, I would know (fully knows)
