Dp x Spiderman x DC prompt
"Danny Phantom and Peter Parker Aka Spiderman are sent to the DC universe and they will make that everyone's problem."
For whatever reason, whether to protect him, because he loves chaos, or just because he was bored, Clockwork sends Danny to another universe even if Danny doesn't agree with it. Anyway, now Danny is stuck in the DC universe, and he's drawn to a city dripping with ectoplasm and crime, and looking for a way to get home or whatever Clockwork wants him to do, Danny heads to Gotham City.
At the same time in another universe, as a last resort and to protect his universe and his loved ones, Spider-Man, Peter Parker is erased from everyone's minds and his world, so he is sent as a last act of kindness and gratitud from Doctor Strange to another universe so he can start over. So Peter awakes in another universe and new world, one where super heroes exist but no person he knows has ever existed and where there are no records of his own existence, and to make matters worse, he's 14 now and he's in a city infested with criminals, villains and pollution. Seriously, not even New York is this bad.
Looking around for how to survive, a place to stay and how to get home, Peter's spider sense alerts him of a powerful presence approaching, and Danny flying through the city while invisible is paralyzed in mid-air when a boy wearing a suit under an oversized coat looks directly at him, as if he could really know he's there, and after hesitating for a couple of seconds he becomes tangible and the other boy's eyes widen comically in surprise, and they both take a defensive stance. They have a staring standoff for a couple of minutes in which they determine whether or not the other is a threat, and when that is resolved, Danny and Peter meet. Quickly after an exchange of information, they discover that they have a lot in common, they're both young heroes, with more responsibilities and power than they could ever expect, underestimated and misunderstood teenagers, geeks, with a similar humor, show true interest in each other's tastes, and are stuck in another universe with no way to return home, oh and they share the same principles and morals, so naturally they become best friends and decide to survive together.
Danny really likes Peter Aka Spiderman, it's the first time he's met someone in his age range who really understands what he's going through. But that's not just why he likes him, Peter is funny, smart, kind, sweet and genuinely a good person, and a kid, one who in his short years of life has already been through too much, (they did trauma dump on each other) and Danny and his ever-evolving ghost core who is now obsessed with protecting children, wants Peter safe and happy, and by their side, so considering that Peter's universe and the people in it no longer existe for him, they both emerge with a plan, they are going to stay together in this universe for now and then find a way to leave together to Danny's universe, and for that they come up with the idea of building a portal. They trust that they can do it, they're smart and have enough knowledge to maybe and by putting both brains together, they can decipher travel between universes, or at least to the ghost zone. But for that they need equipment, tools, materials and a safe place to stay and be able to start working, and with an established plan, their journey begins.
They find an old building, house, warehouse (it doesn't really matter) and they take it as their new home, and it's perfect, it's in fairly good shape, it's safe and secluded enough that no one will bother them while they work, it's away from most of the criminal gangs, gang territories, and off the territory and radar of the local vigilantes, vigilantes that Danny and Peter were quickly aware of dominate the streets of Gotham, and don't accept people with superhuman abilities on them. They still have to go out into the streets to get supplies and materials to build the portal, and because being two young superheroes they can't help but fight crime for a long time, and in fact they make a good team. Who would think their skills would work so well combined? (I did. I actually thought about it quite a bit, and I could have a whole conversation on this topic alone.)
There are two new vigilantes in Gotham and they are metas, that's what everyone talks about in the streets, and it's what the bats and birds have seen, and they are concern. These meta vigilantes don't seem remotely affected by Batman's rule of no metas in Gotham, but that's not what's relevant to the Bat and the Bat Kids, it's how young they are, not much older than Damian or Tim, with flashy uniforms and even flashier powers, if not dangerous, they're reckless, and their origins and reasons for being in Gotham are unknown. They know that they must approach this situation delicately, if they don't want it to get out of hand. And since they are in the streets and seem friendly, the bats try to get closer and get information, they try on different occasions and with different methods, but they don't obtain great results from any of the encounters. If the new young vigilantes don't escape and disappear completely just by noticing the presence of the bats or birds (they always know where they are no matter who or how stealthy they are), they respond with jokes or sarcastic comments to any question, sometimes insults if they are not in the mood for an interrogation, they never fight or attack but they refuse to have a relationship with the local Gotham vigilantes, and after two months of this all they know is that the one in red and blue is Spiderman and the one in black and white is Phantom, and that's driving them all crazy, especially when in the few times they've faced them (they tried to capture one of them, it doesn't matter who, it's not a good idea) they have shown that they know how to defend themselves and that their abilities should not be underestimated, and if you try to go after one of them, the other will go against you with everything he has (I like to think that Peter and Danny would be overprotective of each other since they are the only thing the other one have in that universe and they are not going to lose their best friend if they can help it). The bats learned this the hard way and now know what to expect from each one of them. At the moment, the one who has shown that he could have the best chance of being a real threat in the future is Phantom, who managed to give a good scare to Nighwing and Red Hood and everyone who was around to witness it when the vigilantes were very close to capturing Spiderman, but as long as you don't touch his friend he's harmless (although there are suspicions that Phantom fell into the Lazarus pit, a classic), but Batman learned that if you try to hurt or capture Phantom, Spiderman will have no problem crushing you and breaking your ribs, again (first time was an accident, Peter felt really bad about it), he just didn't do it a second time because Robin was present and stopped himself so the little kid vigilante wouldn't be scared of him, so Batman knew from experience, although less scary and calm than Phantom, Spiderman is a time bomb and it's better not to give him reasons to explode.
So the bats keep their distance, as long as the new vigilantes don't hurt anyone or commit any crimes they decide that they can coexist in Gotham peacefully, and maybe collaborate if the opportunity arises and they need extra help. But then things start disappearing from Wayne Enterprises and some hospitals, and blackouts are reported, and strong shocks of static energy shake the city (Danny and Peter have begun their research and experimenting with the new technology they have in this universe, they're doing their best). None of Gotham's villains or criminals are responsible, so the main suspects soon become the new and enigmatic vigilantes. Now the real game begins, imagine the efforts the Batfamily would go to to obtain information and slowly gain the trust of Danny and Peter, all the interesting situations and interactions we could get out of this, I don't know, I think we could get at least 6 different stories out of this idea with all the juicy stuff a crossover likes this can offer.
