Usually it’s Danny talking about his crush but let’s flip it.
Jason feeling so left out and discarded by family that he has his own “guy in the chair” bc he doesn’t know if he can trust Oracle more like if she trusts him he doesn’t wanna know the answer.
His “guy in the chair” is Tucker Foley. Met the guy on a case at Gotham U. Tucker helped him hack into a encrypted USB. And then just, kept asking him for help.
They get close enough friendship where Jason feels comfortable without the helmet (and maybe without the domino mask too).
Tucker by now expects Hood to climb through his dorm window and throw a gadget at him to hack into and reverse engineer.
What he did not expect was what Hood was gushing about.
“God you know that ghost boy Phantom? He’s so small and cute I wanna squish him. Like talk about a zombie’s dream boyfriend. Don’t tell my brother but I like Phantom’s puns better than Nightwing’s.”
Unbeknownst to Jason, Danny is actually Tucker's roommate. They, along with Sam and Jazz, all decided to go to Gotham U for their different majors. (Tucker- technology, Danny- aerospace engineering, Sam- environmental science, Jazz- psychology)
Danny and Jason have never run into one another in Tucker and Danny's shared dorm room because Danny works the closing shift at his job, does some vigilante work afterwards, and then sleeps through the morning until his classes, which are all scheduled in the afternoon.
Jason trying to explain the “pro and con” list of dating them to Tucker to help him ask out one of them.
“Phantom understands the you know, being dead part, but my dad isn’t too fond of non Gotham native meta’s and we just started talking again. Like I’m all for saying fuck it to parent’s dating expectations but being back on Batman’s good side was lots of work-”
“Wait wait Batman’s yo-”
“But if I bring Danny home next thing you know he’s gonna become my brother because again my dad has no impulse control. Lonely black haired, blue eyed, and younger than him is basically a requirement. Welcome to the world Danny Wayne everyone! Not through marriage, no, because rich billionaires don’t know how else to fill up his empty mansion.”
“…wayn-?”
“Phantom can’t die so me being Red Hood wouldn’t get him hurt like it would Danny. But other heroes talk about dating civilians and having that ‘sense of normalcy’ at home so it doesn’t always feel like you’re ’on the clock’ and I do miss that. Danny would be that for me. But again, if my identity got out or his connection with me at all, he’s in the line of fire. What’s your opinion Phara0h?”
Tucker, he really wants to spill it all out right there. He’s never seen Hood like this before. It’s…worrying. But Hood’s also mentioned that Tucker’s kinda his only trusted friend right now. Trusted friends play pranks on each other right?
“Maybe ask them both if they would be up for a poly thing?”
Ok but cue Danny telling Tucker the exact same thing.
"Tucker, you're not gonna believe this, but remember that cute zombie that was in our room? Today I met another one. He goes by Red Hood? He's a vigilante. I kinda...followed him around for awhile and maybe have a crush on him?
Anyway...do you think I should try to date him, or the Jason guy you're friends with?"
Bruce sat in front of the Batcomputer rubbing his eyes. Usually it would be about that time that Alfred would bring out the tranquilizer gun, but this was too important for sleep. At this rate he’s going to pass out in a meeting for Wayne enterprises and just blame it on chaperoning a party one of his kids threw.
Damien was developing powers. He shouldn’t have powers.
Nether him or Talia carry the meta-gene, Damien hasn’t even been dumped in chemicals.
It started somewhat simple, invisibility, odd but not a reason to worry, but then came intangibility and flight. Then Bruce stopped sleeping.
He was willing to shrug off the invisibility as just an odd occurrence that will eventually disappear. But Damien could get seriously hurt if his powers went haywire at a bad time.
Then on top of that bruce couldn’t figure out why. 
He finally decided to break and test Damien‘s DNA, now he was just waiting for the results.
Bruce was half asleep when the Computer chimes indicating that the testing was complete.
When he opens the file it felt like Clark sucker punched him.
There are ecto-detectors in the Batcave.
Sometimes, they'll go off for no discernable reason.
This is why Bruce tells the kids to behave when they're in the cave.
The entity isn't Deadman, he knows that for sure. They don't mean harm or any malicious intent, or they wouldn't be able to get past the barriers. There's no poltergeist activity, so they aren't bored and there to deliberately cause chaos.
When he opted to look through the thermal imaging one day, once the ecto-detectors stop alerting, he sees a cold spot roughly the same size as Damian. It's sitting on the edge of the cave, swinging it's feet, and just, as the kids would say, vibing.
He decides to leave it alone. The dead can't really impact the living, and it appears that this one just shows up for some peace and quiet now and then.
He tunes the detectors to this particular entity's signature and sets them to silent. He'll still get an alert, but it'll only go to him.
Months later, when he finds himself mind controlled and helpless to do anything but watch himself attack his own family, he feels a cold sensation permeate through his body, and his punch freezes in the air before he feels his arms forcibly dropped to his sides.
Then, a tween girls voice comes out of his mouth.
"Okay, I've got him restrained. What next?"
Or; Dani likes the "ambient" side of Youtube. So much that it's no longer good enough for her, and she seeks out places that have good ambience. She prefers caves, but her favorite combination is cave sounds, waterfalls, papers shuffling, distant conversation, and computer typing.
This means the Batcave is literally the most perfect place ever if things get to be too much.
Her second favorite sounds are snowstorms, high tech beeps, the creaking of ice, and radio chatter. So her second favorite place to hang out is in the Arctic, in some fortress made of ice.
But there's not really a lot to do around it, so she doesn't go there that often.
She ends up hanging around Metropolis and Gotham just due to proximity to her favorite hang out spot, mostly staying out of sight.
She doesn't really care about who the Bats are, so long as they stay out of her hair. But she won't lie about getting a little bit attached from her creepy totally-not-spying thing.
Then Batman gets himself mind controlled, and he's about to lay out Robin, and all Dani can think about is Vlad and his 'discipline'.
She possesses Batman and forces him to stop.
The gig is up. Farewell sweet hangout spot, it was her favorite.
There were a few minutes every morning, in the dark before dawn when his alarm hadn’t yet rung, where Dick Grayson felt most at peace. Despite the ache in his body the night out as Nightwing, he felt refreshed and content to just rest his eyes until his phone rang and it was time to get ready for the day.
Unfortunately, peace was never meant to last.
With a loud crash that definitely woke the neighbors, a little body kicked his door in. A switch was flipped and blinding light filled the room. Dick squinted in the general direction of the intruder. “Get up already!” Danny, his ward, snapped, rushing forward to rip the blankets off his bed. Dick let him. “There’s a case ready for us at the precinct!”
Dick checked his phone. No missed calls, and Danny didn’t have a phone yet. “Is this another psychic thing?” he asked.
Danny rolled his eyes. “If I say yes, will you get your ass out of bed already?”
“Language,” he chided absentmindedly, but still got out of bed. Danny glared up at him, still not satisfied, and dragged him to the bathroom with a surprising amount of strength for an 8-year-old. “Huh! You’re really in a hurry today.”
“No, you’re just super slow!”
Dick pulled back against Danny, slowing their progress considerably. “Oh, it’s the age!” Dick bemoaned, draping himself dramatically against the wall. “Now that I have a kid of my own to look after, the years have started to take their toll—Ow!”
Danny glared up at him like he hadn’t just kicked Dick in the shin. Brat. “Be dramatic in your own time! We have a case, Dick, we need to go!”
“Alright, alright, I’m going!” Dick complied and got in the bathroom, saying just before he closed the door, “Make sure you’re dressed in clothes you can afford to lose! I don’t want you to get blood on your favorite jeans again!” Danny shouted back his agreement and finally, Dick was alone.
As Dick washed his face and did his business, he contemplated how he got there. Honestly, he didn’t get what Bruce was always complaining about; this guardianship thing was going great! It was three weeks since he’d wrangled Danny home, but he’d been preparing for this for months, ever since he learned that the little brat trying to solve murders was homeless. It took months of classes, meetings with CPS, and interviews with friends and family, but Dick was now the proud foster parent of Danny Smith!
Fortunately, Dick had managed to convince Bruce that the foster license was precautionary, like if he needed to protect a minor. Which was what he was doing! So not technically a lie!
Although, Bruce had his hands full already. Some new crime lord had taken up the Joker’s old alias and it was driving the old man up the wall. Bruce had even asked Dick for help on the case last night! He’d said no, of course; he wasn’t just going to abandon Danny in Bludhaven for days while they hunted down Red Hood, and he wasn’t going to spring Danny on Bruce, nor Bruce on Danny. Danny was a flight risk and had expressed disdain for millionaires in the past, and Bruce was… worse than he used to be. Tim had managed to resurrect some of the dad Bruce used to be, but ever since Jason…
Well, it was good that they wouldn’t be seeing each other any time soon. Maybe by then Tim will have convinced Bruce to go to therapy!
Coming out of the bathroom, Dick started at Danny, dressed in jeans and a Digimon t-shirt, standing on the counter and getting Dick’s lunch bag off the shelf. He cocked an eyebrow. “What are you doing?”
“Packing breakfast to-go!” Danny said, jumping off the counter. Dick’s heart skipped a beat and he lunged forward, but Danny landed before Dick could reach him. He glared at Dick. “What are you doing?”
“Nothing.” He straightened up, playing it cool. He observed what Danny had laid out for breakfast as he started the coffee machine. A banana, two yogurts, and a handful of granola just poured out onto the table. “You know, you absorb more nutrients when you sit down and actually enjoy your food. And we don’t need lunch to-go. Remember, we talked about this? We have to wait for someone to report the crime first.”
“How do you know no one hasn’t yet?” Danny challenged.
“Have they?”
“...No. We could report the crime though,” Danny grumbled, but opened a yogurt cup.
They really couldn’t. If they reported the crime, they’d still have to wait for other officers and CSI before investigating, and that’s even if they were given the case! But more importantly… Dick was the only officer in the department who believed Danny could see ghosts.
Sure, Commissioner Gonzalez believed Danny, but that was just one woman. As much as he appreciated the Commissioner’s work helping get Danny off the streets and processing the paperwork to ensure the boy got recognition as an official BPD consultant… well, Dick knew she had ties to the gangs in town, he just couldn’t prove it. Just because she liked him and Danny doesn’t make her good.
The fact that she promoted him to detective was evidence enough. Dick was an amazing detective—like everyone trained by Batman—but normally you’d need a certain number of years and successful cases for that level of promotion, both of which Dick didn’t have. Hell, he’d only been working as a cop for two years! But Danny was only willing to work with Dick… so Dick became the youngest detective in the city.
The coffee machine sang a little robotic song and Dick placed a Nightwing mug under the spout just in time to catch the stream. As Danny finished his breakfast, Dick shooed him off to go brush his teeth and turned on the TV. He still had thirty minutes before they had to leave for work—
“—taking after his father!” Jack Rider’s voice rang through the apartment. Dick frowned; why was this trash on? “Although I have to say, I don’t think anyone ever expected Richard Grayson to adopt a child of his own!”
Dick froze. What? No, he’d worked so hard to ensure that no one would find out—
A picture flashed on screen of Dick and Danny. Dick recognized it immediately; he’d taken Danny out to eat to celebrate Danny officially becoming his foster child. But that was weeks ago! They’d been sitting on the story for that long?
They didn’t even bother to blur Danny’s face.
“Now, Jack,” the co-host chided, “Let’s not get too hasty. Our source at Bludhaven PD—who will be unnamed to protect their privacy—said it was only a foster, not an adoption.”
Jack waved her concern away. “Yes, a foster. For now. Don’t you remember how long Richard was Brucie’s ward? Sure, the kid might only be a foster for now, but with this family, adoption is always on the table!”
Turning away from the TV, Dick checked their security cameras on his phone. When he’d first moved in, Babs had hacked into all the cameras in the apartment, piggy-backing off their feeds. There, outside the building’s main entrance, were multiple reporters. Some had even gotten into the building, although their aimless wandering told him that their apartment number hadn’t been leaked yet.
“Still, another street kid in the family,” Jack continued to muse. “That’s two now for the Waynes, right? Are they going to take off with an entire orphanage next?”
“Dick?”
He locked eyes with Danny, who gave the TV a worried look. But Danny didn’t get worried; he was a cocky, grumpy brat who’d given Dick a heart attack when he dared a gang member to shoot him in the face. But a news story scared him?
Smart kid. Dick was feeling scared too. So, he made the executive decision.
Dick knelt down to Danny’s height, gently grasping his shoulders. “Okay. Here’s what we’re going to do. I’m going to call out of work—”
“But Mrs. Bennett’s murder!” came the immediate protest.
Dick took note of the name, but held up a hand to stop him. “I know, I know. But it’s not safe for us to go to the precinct right now.” Someone at BPD had told the reporters about them. One of his colleagues, pissed that he’d gotten his promotion unfairly? Someone who hated that a little kid solved murders better than them? Or anyone looking to make a quick buck? The possibilities were endless.
He continued, “Commissioner Gonzalez will understand and help us consult with the case from online, okay? We’ll get sent pictures of the crime scene and you can talk to Mrs. Bennett and we’ll consult from Gotham just to be safe.” He had some PTO he could use, right? If not… Gonzalez could just fire him. He’d already known his co-workers were corrupt assholes, but to willingly put a child in danger was a step too far. If Gonzalez wanted to keep Dick—and therefore, Danny—she’d better clean house.
Danny made a face. “Why Gotham?”
“That’s where my family lives! While we wait for the story to die down, I’ll introduce you to my grandfather, Alfred, and my brother Tim, and my friend, Barbra! I’ll show you around to all the fun spots, it’ll be fun! So go get packed, buddy.”
Hesitating in the doorway, Danny said, “They won’t listen to me. The other officers aren’t like you.”
“They will listen to you. I’ll make them,” Dick promised. He’d gathered enough blackmail on his fellow detectives to force the issue, if needs be. He ruffled Danny’s hair. “Don’t worry, Danny. It’ll just be for a week or two and then everything will be back to normal. I promise.”
Danny glared at him, batting his hand away. “I’ll keep you to that promise, old man.”
As Danny retreated to his room—Dick’s former workout room—to pack, Dick went to his own, closing and locking the door behind him. The call to Gonzalez went about as well as he was expecting: first her anger at him taking time off, then his anger about being sold out to the media, then Gonzalez swearing as she found the news online, until finally agreement.
As they talked, Dick methodically packed away his Nightwing gear. After last night, where a slime meta had unceremoniously caked his suit in gunk that would not come out, he had two functioning suits: his back-up and his original that he kept for sentimental value. He packed all three, along with his gear. Maybe Alfred would be able to get the gunk out? But he couldn’t leave his things here. Their location was already compromised. If reporters decided the risk was worth it, they could break into his apartment and turn the whole place upside down looking for a story.
So, Dick had to take the story with him.
With all his gear packed, there was little room for personal belongings, so he did the best he could and only took the important things. His room at the manor still had a few changes of clothes. Fortunately Danny wasn’t a nosy kid, otherwise he’d never be able to get away with carrying his Nightwing gear in a normal duffel bag like this.
Now, the hard part.
The phone rang three times before it was picked up. “Master Richard.” Alfred’s icy tone made him wince. Oh, he already knew. “To what do I owe the pleasure?”
“Hey, Alfie…” Dick rubbed the back of his neck. “I just wanted to say that I decided I can help Bruce on that Red Hood case after all?”
“I see.” No matter how angry Alfred was, he was frighteningly polite. “And shall I prepare a second bedroom for your ward?”
Dick winced. “That would be great, Alfred. Thank you.”
“Then I will see you soon. And please inform the young master that I look forward to meeting him when you both arrive.”
“I’ll tell him. He’s been looking forward to meeting you; I’ve been talking up your cooking for months now.”
“Months?” Oh no. “How kind of you, Master Grayson.” It got worse. Alfred was pissed now. Why did he have to say months? It wasn’t like Dick had intentionally hidden Danny from his family; he was just hiding him from Bruce! He wanted some privacy and to figure things out himself! But now Alfie was mad and suddenly that privacy didn’t seem so important anymore. “Shall I assume you’ll be arriving soon then?”
“In around an hour.” Leaving his room, he checked on Danny. He was trying to back everything he owned into the suitcase Dick had bought him. “Maybe a little longer? I’ll call when we’re ten minutes away.”
Lois was snuggled up next to her husband when a loud knock at the front door. Clark buries his head under his pillow.
“Lois can you get it?…” He says tiredly, he only got home thirty minutes ago because he was helping with a earthquake in Japan.
Lois kisses his shoulder and pats his head under his pillow. “Sure Smallville…” Lois wraps her house coat around herself then walks to their front door, opening it to see a rattled teenage boy.
He was too thin, dark bags under his eyes that she only ever seen on Bruce after he had to work for four days straight. “Hello?…”
The boy shoves papers in her hands. “Hi mom…”
Lois stands there in shock for a few seconds before ushering the boy inside.
Danny watches as his mom reads over his adoption papers, he really hoped she would except him.
“Ok… ok… we have a guest room… what should I call you?…” Danny could see gears turning in her head at 1,000,000 mph. At least she wasn’t transphobic.
“Danny… my names Danny…” Lois nods then drags him up a flight of stairs and in the second door to the left.
“You need to sleep… then we can figure everything else out in the morning… if he wakes up before me, don’t be scared of my husband, he may look intimidating, but he’s the biggest softly. Just give him the papers you gave me, ok?” She puts his adoption papers on his nightstand and then gently kisses his forehead. “You’ll have a eventful morning tomorrow… your little brother will be bouncing off the walls…” She lovingly ruffles his hair before leaving and closing the door behind her.
Danny flops onto the bed and stares at the ceiling.
Lois paces up and down the hallway. Why was her d-son here now? Why did he look like death frozen over? How would Clark react? She hoped that he would be welcoming, but she knows he didn’t react well the last time he had a teenage son dropped on him. She gives up on going back to sleep and works on a article about a gang in Metropolis.
Constantine was in the house of mystery when suddenly a portal opened and Clockwork came out and placed a bundle in the laughing magician's arms. "Wha-" Constantine froze as he moves part of the cloak revealing a two year old boy with white hair with a black shock running through it. "This is Prince Phantom, champion of the realms and my appreciate, he's met with a terrible accident and needs a guardian until he regains his strength." Clockwork said just as Constantine tore his eyes from the sleeping baby God in his arms to ask questions Clockwork and the portal were gone. "....bloody hell..." Constantine mumbles
It was his day off, his day to reread Pride and Prejudice in lavender bubble bath.
But no Bruce had to make him go out and stop a cult. A cult that had to be in Gotham to do their fucked up ritual because it seemed every god hated the city.
Jason does his best to sneak around the abandoned the warehouse. The cultists zipped around like flies, with seemingly no rhyme or reason to their movement. 
They were dressed in intricate black and white robes, shiny emeralds enbedded into necklaces and bracelets. He had to give the points for commitment.
Who Jason assumed was the leader barked orders in a strange language. It all seemed to boil down to move this over, draw this sigil, fix your robe. Jason waited hidden in the shadows, trying to find an opening to stop them. It was real, and Gotham didn’t need any more demons roaming her streets. 
The ritual started without any warning. Usually, cults warm up or get into place before starting their chant. They swayed and turned in a strange dance. Harmonized voices pounded in Jason’s skull like a migraine, and the circle was the sun.
 Jason’s muscles felt like jelly. He leans into the box, magic fills the air. He felt like he was suffocating. He felt like he could breathe for the first time.
Green magic danced like the forming of a cosmos. Stars hungrily gobbling planets, planets crashing and shattering into asteroids.
Up was down. Down was up. Ice burned and fire froze.
Jason fainted.
“Are you ok?…” A voice like whispers of the deep rang through Jason’s ears. 
Jason was held in cold hands. His helmet was off, he had never been more thankful for his paranoia that made him wear a domino under his helmet.
Jason blinked his eyes open, his head felt like it was split open.
He knew that face, the look in the creature's cold yet somehow kind eyes. Even if his skin was sickly pale, his lips frostbit, his hair snow white, he knew that face.
It was motherfucking Danny.
Jason shoves the being away from him. “When I asked if you were a meta! This would be included!” Jason shouts to the best of his ability through his aching lungs.
Danny rubs the back of his neck, giving Jason an awkward smile. “Does this mean I’m fired?”
“No, but you're working until midnight for two months” Jason grumbles, now registering he’s in a small apartment on the outskirts of Crime Alley.
Danny chuckles and presses a clawed hand on Jason’s forehead to act as an ice pack.
(Sorry if this is bad I wrote it quickly, but this is such a cool idea)
A little after Clockwork adopted Danny he decided to throw a "family reunion" to introduce him to his new siblings and nieces and nephews. Admittedly, he did forget that he never apologized for the time he went crazy with power and ate his kids until he received a response from his oldest, Hestia, asking him if this was a plot of some kind. (She also seemed to be open to reconciliation though, so he was hopeful)
Wonder Woman had been chatting with Hawkwoman when a glowing green envelope appeared on the table in front of her with her name on it.
I've seen people say that this would make a better dp x percy jackson crossover prompt, but - while I do agree - I'm not a percy jackson fan. which is kind of ironic considering how much I love mythology and such.
I did have more ideas for this in regards to interactions such as:
Diana bringing Zatanna or Captain Marvel as her "plus one" (because she doesn't trust cronos, circe, and a few other gods/goddesses/titans)
The awkwardness of her father asking about her mom.
Athena trying to convince her to join the ranks of the gods as the new goddess of truth
Danny being overwhelmed with how many names he's going to have to keep track of.
Danny freaking out that he's now the uncle of (or great uncle of depending on continuity) Wonder Woman who happens to be one of the world's best superheroes.
Diana and her plus one trying to figure out if Danny's a threat to earth or not.
If her plus one is Cap (and we use the twitch chat au), then he's trying to avoid Zeus, Achilles, Atlas, and Hercules (and Hermes/Mercury) because he's stuck with them in his head anyway, he doesn't need to talk to them in person
It doesn't help when Zeus, Achilles, Atlas, and Heracles are all trying to come talk to him, I can see Hera grabbing Zeus and Hercules by the ears and dragging them off.
I can see Hephestus, Aphrodite, Persephone, and Hades actually coming over and talking to Clockwork. And Hades, knowing Danny is the Ghost King, Greets his new boss as such, which gets Everyone looking at Danny like, 'I'm sorry who and the what???'.
And Rhea, The titaness of Lions, the mother of the original Olympians, and Wife of Clockwork, is just doting over her new son, as well as crying that her Husband is back and has returned to his old self.
Unstoppable Force: Dick Grayson, mourning Father older brother who is grieving because Damian died and he has a chance to ask if he's happy in the afterlife via The Ghost King.
VS.
Immovable Object: Danny Fenton, who knows Damian's alive because they've been going out for a year now and is about to be so funny.
Ok so instead of traveling the world and training with all of the best marshal art masters, Bruce just spends those years in Amity with the Madisons.
Alfred can tell Bruce is getting restless in Gotham, every time he goes out people are shoving a camera in his face, and the whispers. Alfred can tell when they get bad, Bruce locks himself In his room and refuses to come out.
Alfred decides to take Bruce to live with some family friends, the Madisons.
Bruce and Sam get on like a wildfire. Both being moody teens with a interest in making the world a better place.
Bruce gets introduced into Danny’s friend group easily during freshman year. Even if he wasn’t there for the accident, it wasn’t hard to figure out that Danny wasn’t… entirely human. He plays oblivious until they are ready to tell them, before Jazz I imagine.
So Bruce becomes the fourth member of team phantom, helping Danny feel out hero work. Mostly teaching him the hand to hand combat he’s been working on ever since his parents murder.
When it comes time for Bruce to go back to Gotham in his early 20s he promises to keep in touch with the rest of the team. Even keeping some of the equipment, just in case.
His paranoia paid off when a few decades later a ghost attacks and no one knows what to do. Even the JLD is at a loss because none of them have ever seen a ghost like that,
The hopelessness soon turns into panic when Batman walks into the battlefield holding what looks like a thermos, sucks the ghost into it, and says ‘soup time’ with a smirk.
Bruce: Hmm, Alfred sent me stay with distant cousins. Gotham was a bit much after my parents murder. Phantom wasn't king yet. I was living with one of his future consorts. Queen Sam, Daughter of Undergrowth. So I was a part of Team Phantom.
John: You, you know the three of them? You were part of Team Phantom? The original team?
Bruce: Why do you think we all wore masks? Phantom didn't see the point at first. But I made a good case for all of us having suits.
John: Oh, oh no. you were the shadow weren't you?
Bruce *smug*:Yes. My kids all know his kids as well. Since he can portal he brings his family over probably every few weeks? Helps him keep on with our dimensions news. And he helped me take down the League of Assassins. Their Lazarus Pits were run off ecto. So we took them all back. The League are still around, just... weaker now.
John: Fuck. What the FUCK! Do you think he would be willing to talk to me?
Bruce: Given how much he cackles every time your name comes up? I'd say yes.
John: The King of the Infinite Fuckin' Realms knows me name? HOW!
Bruce: Demons come from hell, hell is an afterlife. He is the King of ALL afterlives. Demons are his subordinates. He loves the chaos you caused with your contracts. He respects people who can fuck demons over. If it wouldn't damage the Realms he would probably end most demons.
Ok so it's safe the assume the Anti-Ecto Acts either never happened or didn't last long since Bruce is part of Team Phantom but what if little baby Bruce COULDN'T get rid of the Anti-Ecto Acts and it ended up being one of those things he was working on, mainly because by the time baby Bruce was able to come back and become The Batman the Acts were in place so long dislodgeing them is a pain in the ass. So he's able to do it but not until after the Justice League is formed
It's why he pushed so hard for the Meta acts. Cause they would supercede the anti-ecto acts. Mwahaha, cunning plan etc. But he also just helped Tucker divert all of their funding so they were just a massive money sink hole, making it WAY harder for the government to enforce them.
Even if it does supercede them, sadly, the fact the Anti-Ecto Acts still declare ghosts and ecto-entities to be insentient still causes problems from time to time, mainly when ghost hunters and GIW try to use it as a loop hole to get around the Meta Protection Acts. It causes a huge headache he for Batman that he's still trying to get rid of, one that won't be gotten rid of until the Anti-Ecto Acts and the GIW are completely abolished. In fact, he and Danny (when he comes to pick up the ghost) even get into a discussion about his progress so far. Superman overhears and, being Clark Kent, is very interested in the situation. As does Green Lantern gain an interest in the Acts. Suddenly, Batman's one man assault against the act deeming his childhood friend insentient gains a lot more support.
The no Meta rule for Gotham changes too. Suddenly it's not "No Metas in Gotham" it "No Metas Without MY Knowledge" mainly because all it took was one surprise visit from Danny when there was a Fear Gas incident. The mess was enormous and it took ages to calm Danny down. He had to be souped for almost an entire day!!
No destruction. Lot's of mess though! He started a prank war with the kids and Harley. It took months for the glitter to be cleared away fully. Gotham had never been so bright.
Bruce is liminal as fuck. Batman's spooky vibes are not entirely an act. He fits more into his utility belt than small belt pouches should be able to hold. His cape is made at least partially with ectoplasm, so the way it seems to blend with the shadows and shroud him in darkness is not entirely an optical illusion.
He automatically forms ghostly familial bonds with all his kids as soon as they are accustomed enough to ectoplasm to reciprocate. He realized the minute Jason is in real danger and sounds the alarm.
Instead of the Joker beating Jason to death with a crowbar, Sam puts the smackdown on the Joker with a Morningstar. Tucker gets the whole thing on film.
Because of the nature of ghostly bonds, his kids are more aware of how much he loves them and how proud he is of them, and all of the relationships within the Batfam are healthier for it. He still sucks at communicating emotions with people he doesn't have bonds with, though.
Bruce visits his parents in the ghost zone and is a little less fucked up for having the option.
Dick can visit his parents in the ghost zone! Jason can visit Catherine, who's finally free of her addiction and building a good afterlife for herself.
The Waynes have a clinic for ghost medicine. The Graysons are taking their art to the next level now that they can actually fly. Things will never be the same as they were, but there is hope and renewal and the simple knowledge that there is more to come.
Wow, that took an emotional turn I wasn't expecting.
He has no idea how the fuck the dude gives back massages that quiet the goddam pit but you bet your ass Jason is recommending Danny to anyone who looks like they need a massage.
Ghost King Danny in his large eldritch form, staring down at the human before him: So. You are the human that has been deemed worthy as a sacrifice~.
Wayne child who is also an extreme exophiliac: *heavy breathing* U-uh, yeah! That's me! Ready to be under-I mean! In your care! *nervous chuckles*....how sharp are your teeth?
