The Fenton parents don't know that Danny is Phantom
but they do know about ghosts
Because the Fentons are scientists. Ectobiologists. They study ghosts.
The reason they started going on and on about tearing ghosts apart/hunting them once the portal was open?
It's because in the month or so Danny was figuring out how not to sink through things, his parents were doing science. And figuring out that fighting is a natural part of ghost socialization (via observing animal ghost behaviors & maybe a few probes. Maybe they even visit the zone - you cannot tell me they made a whole entire Specter Speeder for traveling the Zone only to Never Use It).
So when Phantom shows up and deals with all of the other ghosts before they can get to him? That's exciting. Because it seems that he's trying to haunt all of Amity.
That's great. Because ghosts zipping over for a visit is one thing, but the chance to observe a ghost in a location they are actively haunting? Where they - well, not live - but where they dwell? 10/10. They are in science heaven.
Now if he would just stick around long enough to actually fight with them!
See, they don't know exactly how ghosts differentiate between friendly and unfriendly combat. There's a lot of nuance and they can sometimes parse it, but... it's hard to judge exactly how to go about things without more experience.
They figure it would be a slight to be seen as treating the ghost with kid gloves, but they don't want to risk coming across as a real threat just in case they make a misstep and come across as unfriednly - a weak unfriendly and Phantom might still interact with them some. But if they're perceived as strong and unfriendly they might never see him again.
For all that they could track him, Jack and Maddie have no illusions about the sheer infinity of the GZ. If Phantom disappears into it, they could track him, they could follow. But Phantom never has to rest, Jack and Maddie will eventually tire, will have to go home for resources. Better not to chase him off.
So instead, they crank their weapons to the lowest setting and they play up the goofy parts of their personalities and behaviors - things Phantom will hear about them from any other humans that might choose to talk about them. This will avoid their behavior being seen as manufactured, despite the exaggeration being exactly so.
And after one of their more dangerous-to-ghosts weapons (that was made only for emergencies) goes missing after they talk about it with their kids?
They start talking up other More Dangerous Weapons.
Just once, they glimpse the wisp of Phantoms tail disappearing through their lab ceiling with a weapon left behind.
They can hardly contain their glee at yet another point of contact. A race of make-dangerous-weapons vs dismantle-before-they-can-be-used-against-me is it's own type of fight, if more indirect than they'd expected (and, again, even more exciting).
They continue the trend, talking up Super Harsh Weapons and finding them taken apart.
This is great. Not only does it give them a glimpse into the ghosts mind by observing how it takes things apart, but the continued pattern should allow the ghost to build confidence. They continue to prove capable of strength with their designs, but they also prove thwartable with their lax security in addition to their "bumbling" act in public (though Jack will confess he is occasionally Actually That Distracted...)
Instead of fleeing on sight, Phantom starts bantering with them!
Only a little, and it's not like they can hear more than a syllable, most of the time, but it's progress!
So on the one side you have ghost-focused Jack & Maddie completely unaware that their son is Phantom (they know he has an ecto sig, they just blame contamination)
And on the other side you have Danny, who is completely convinced that his parents genuinely want to frog-in-biology-class his ghost half, utterly unaware that most of the missed shots are intentional or that the guns have a setting higher than *okay-ish punch*
It happens like this: the first distress calls from Amity Park are properly addressed. A member of the JLD goes to investigate pretty much immediately, only to find a ghost protecting the place.
The ghost who's signature is all over the city deftly keeps the civilians from harm's way, drawing the aggressive one's attention to unpopulated areas and containing it in short order.
Amity Park already has a capable hero. The city goes on the low-priority list for deeper investigation, "Inviso-bill" goes on the list of potential recruits, and life goes on.
The attack of Pariah Dark, to the outside world, looks like the city domed itself off, then disappeared off of the face of the Earth for approximately five seconds. Time moves differently in the Zone, and the city was barely missed. When it returns, dome absent, the streets and some citizens are wounded but they're... partying?
Amity Park moves up the "further investigation" list, but the JL has bigger things going on than a city of alive and clearly pretty happy people at that point. They let the government handle investigating for the time being, the JL can follow up once their own disasters have been at least relatively managed. (Not long after "Inviso-bill" is updated to "Phantom" - a relief for Paperwork GuyTM, that first name was awful, honestly)
This incident and the following gov't investigation is, of course, what sparks the GIW into being.
The GIW are government run, but they're an off-the-books group. Meta protections are too broad, covering ghosts within their purview. They can be changed and tweaked to suit the new situation, but it will take time they are not willing to wait. Until then, if the GIW is called out on their actions, if they are taken to court, they will be charged as criminals acting of their own accord. Their funding will net additional charges in the form of theft from the government.
Luckily, they know how to work PR.
If they claim to be government run, that alone will decrease the odds of anyone acting. Fake badges, strict adherence to the uniform - they act like the supporting laws are already in place.
And they make use of Jack and Madeleine Fenton.
Anyone who hears them speak knows the two hate ghosts. Despite this, they claim to be scientist as well as hunters. The GIW take this and run, dedicating resources to drawing up papers on ghosts describing them as evil, non-sentient, incapable of pain or emotion, a danger to the public.
And they publish it all in the name of the Drs Fenton.
The couple seemed scatter-brained enough to forget publishing something, and even if they did notice the discrepancy they wouldn't know to trace it back to the GIW.
With science like that backing them, even the hardcore bleeding hearts likely wouldn't imagine that ghosts might be covered by the Meta Protection Acts.
It may have even worked, if the articles hadn't pinged the JL's systems so hard they called an emergency meeting.
Nothing pings the "something is horribly wrong" button like several supposedly scientific articles detailing how a specific species actually doesn't deserve rights whilst feeling the need to emphasize that they actually aren't sapient or even sentient. The paper doth protest too much and all that.
Things cascade from there.
A quick bit of research reveals a video of the Drs Fenton is a heavily modded vehicle chasing and shooting at a staticky blur while yelling about tearing it apart molecule by molecule.
Another quick search reveals some of their accomplishments - namely, a business website for Fenton Works showing the smiling couple and their two children posing by what looks like an upright Lazarus Pit, but is actually, Constantine assures them, just a portal to hell. (Okay, so he actually said "the afterlife" but part of that would be hell, so the Flash isn't very comforted by the semantics of it all)
To compare the JLD to a hornet's nest that's been used as the ball in a game of soccer would be generous.
News in the afterlife travels slowly, ever so slowly. By the time they find out that the High King of Infinite Realms has been replaced? That the evil but unquestionably absurdly powerful previous king had been defeated in single combat?
It's probably been a month, at least.
Probably. Because the only way they can measure is judging by how many "heard it from XYZ's" Deadman lists before he actually tells them what he heard.
It's awful news, because the old king was locked into an eternal slumber for being too evil and powerful.
Meaning the new guy is both
Powerful enough to kick the old kings ass by himself, making him at least as strong as (but more likely stronger than) 7 ancients combined
Nuts enough to intentionally free Pariah Dark
So the JLD has spent their time since trying to learn more - which has been a nightmare since the new king is either New new, or the most reclusive mf in the damn Infinite Realms.
Or the inherently infinite nature of the realms is just working against their ability to information gather, but they're all very irritated by how many attempts at information have failed after how much effort they've put in for net zero returns in information.
And then they find out that a couple of randos in middle-of-nowhere Illinois ripped a hole into the guys' domain.
And THEN! Promptly started trying to declare his whole species as less intelligent than a rock! And encouraging people to HUNT THEM!?
Even if the new king is peaceful - which is a Very Hopeful sort of "if" given how he got the title - that kind of behavior could be grounds for war.
And listen, if they thought Earth vs alien war might be bad? The US versus every single creature that has ever died would be infinitely worse (no that was not a pun and now Zatanna is looking at Flash like she wants to strangle him).
So the priorities now are: Make the Fentons Stop Doing THAT and prevent the new High King from deciding war with the US (or the whole Earth. Or the entirety of the living realm. Just. Depending on how he takes the slights being leveled against him. Ya know).
Which is how Batman, Superman, and Wonderwoman (each with possession-deterring stuff cast/carried on them courtesy their Dark members) end up at Fenton Works while the JLD themselves work on trying to summon the new king to meet/mitigate/appease depending on what he knows and how he behaves. (VERY HARD since the summoning circle changes depending on the king - there isn't just a "summon king" circle. Someone should really get on that, Constantine thinks, exhausted already - so they have to kind of try a few different things to see what sticks).
They're hoping the reputation of the Big Three will shock-and-awe the Fentons enough to make them more receptive to what they have to say - very important given that what they have to say is "all of your research is wrong we need you to retract these paper and stop hunting ghosts" - ie throw away what is apparently their life's work)
They go as soon as the meeting is over, arriving in the early morning given that they pulled an overnighter to have the meeting.
Which is how they end up sucked into a whirlwind of hospitality on arrival, shuffled in between the Fenton children to have breakfast with the family while the adults regaled them with talk of their inventions.
The daughter - Jazz - tries to deter them with a "no weapons talk during meals" rule, but Jack waves it away with a "But it's Batman! How many times do you get a chance to talk tech with Batman, Jazzybear!"
The girl looks doubtful, but drops it. She and her brother - Danny - had greeted them with paper-thin enthusiasm.
More likely than not, Bruce guesses, they can tell that their visit isn't the good thing their parents seem to believe it is.
"I will not deny that your weapons are impressive," Batman starts after wiping his mouth. "However-" and the word is sharp, necessary to prevent the overly exuberant couple from delving into another longwinded aside before he can finish speaking "-that is not why we're here."
"We are here for several reasons," he begins again after a brief dramatic pause. "None of them pleasant."
The children tense as he pulls a stack of papers out of his cape and slides them across the table to their parents.
"But let's start with these."
He is expecting another exclamation of delight, for the children to be ushered out or for the three of them to be ushered to their lab to talk about their papers more in-depth.
He is not expecting them to hunch over the papers with furrow-browed confusion, followed by shock, followed then by a swiftly growing cascade of anger-outrage-fury.
"What..." Jack Fenton frowns, trailing off in a quiet way that leaves his, for the first time since their arrival, coming across as huge and threatening instead of the till-then golden retriever energy of it.
"We didn't write this!" Madeleine "Maddie" Fenton shrieks, flipping rapidly through the next few dozen pages before both of them freeze.
"NONSENTIENT!?" they bellow, both standing to lean closer over the pages, expressions scornful.
Batman clears his throat a few pages later, drawing their attention back to him.
"We didn't write this," Maddie repeats, voice calm despite the unchanged expression.
"We haven't even finished our first paper yet!" Jack chimes in, nodding sadly. "We're still gathering data!"
Jazz Fenton's voice is small, but it cuts through the room like a knife.
Jack is the one to reply.
"Of course not, Jazzerincess! Science takes data, and the ghosts are so skiddish we can barely interact with them! Any real paper on the topic is going to take time; the portal's only been open for a few months!"
His face is earnest, voice back to nearly booming in his enthusiasm, dulled just slightly by concern.
"Where did you get an idea like that?" Maddie asks.
""Your" papers are all over the GIW web portal. Which everyone who doesn't want to be surprised by one of their "patrols" checks at least once a week," Danny chimes in for the first time all morning, discounting the half-conscious 'mornin' when they were first dragged to the table.
His voice is tight, expression hesitant. "Doesn't help that everything they say is pretty much the same stuff you usually yell at Phantom."
At this moment, the Fenton parents are stricken with horror as they realize that they never discussed their plans with their children. They've heard every threat to the ghosts and they've heard them talk about how their weapons work, but neither of them can recall ever sitting them down somewhere secure and explaining that they're trying to get Phantom to interact with them by seeming friendly.
Never explained to them that fighting is a play behavior for ghosts. And with the articles...
They don't have long to fret over what their children must think of them - ethically or academically - as Batman cuts in again.
"Phantom is another part of why we're here, actually," he says. "Whether you wrote the paper or not, that you've been seen hunting your city’s hero and declaring intentions to experiment on him is still a large issue."
"Ah." Maddie says. "Jack, sweetie, would you get the sweep shield?"
Batman tenses as he moves for the fridge.
"Just a precaution, so we can talk without risk of a ghost overhearing," she hurries to add. "We...probably should have talked about this before. With the kids. Maybe then this-" she brushes a hand through the pile of supposedly-fake articles "-wouldn't have gone so far."
The children exchange a look.
"Talked...about Phantom?" Jazz asks.
Just then a click emerges from where Jack is burried half into the refrigerator, a green energy sweeping out and out and out until it can only be seen out the window, just barely infringing on the sidewalks.
At least until they start closing up the curtains.
Then another button has steel shutters sliding down to close off the kitchen.
Superman taps his knee, a reassurance that he can see out just fine and break the barriers as needed, and Bruce allows himself to relax a smidge. But only a smidge.
For their part, the children are incredibly tense, even when their parents break out a whiteboard and projector, starting up a PowerPoint presentation.
What follows is a breakdown of everything they've learned about ghosts thus far. Every bit of what they know is learned from noninvasive observation, and the numerous slides on social behaviors - really, most of them - are what make him certain that they were telling the truth about the papers.
You don't do social analyses on the behaviors of a species if you don't believe they are capable of such behaviors.
"If you know that ghosts are people then what was all that about tearing Phantom apart molecule-by-molecule!?" Danny shouts, throwing up his hands in exasperation.
For her part, Jazz remains still, blinking rapidly in what looks a bit like shock.
"Didn't you see slides 41-147, Danno? Fighting is a social behavior for ghosts!" Jack exclaims. "Uh, sometimes."
"The exact nuance can be hard to pick up on," Maddie adds, "But our main goal since Phantom started showing up regularly has been to try and lure Phantom into social combat so that we can observe him more closely."
"Maybe he'll even talk to us!" Jack shouts, punching the air.
"Eventually," Maddie emphasizes, patting his arm. "And it's a very loose maybe. It's taken forever just to encourage him to dismantle some of our weapons. It is working, and he's been slightly more chatty with us before running away, but it's slow going."
"...Encouraging him to dismantle your weapons how?" Superman asks.
He regrets it, just a bit, when they pull out a new PowerPoint presentation. They've already been here for hours. The Fentons fed them all Lunch a little over halfway through the first one.
Still, the new one is mercifully brief.
They explain their suspicions about Phantom snooping on them, about finding a weapon dismantle and talking up more weapons. Finding more dismantled. They even charted out weapon type vs time they talked about it vs how long before it was taken apart vs which ones disappeared entirely.
One slide is a graph of how long Phantom has lingered after fights before running away from them over time. Another charts how many syllables he says before bolting over time.
Another about the kind of hits he's taken vs given in attempts to graph his physical strength and durability. Other attributes fill further slides.
One slides includes the rules of their experiment - talking like they hate the ghost, pretending to be aggressive, pretending to miss, keeping their guns on the lowest setting.
A baptized cat would have a less offended expression than Danny Fenton at that moment, Batman thinks.
One slide is dedicated to a brief essay on Phantom's complete and immediate avoidance of them for a solid week after they accidentally clipped him once.
"Why didn't you ever tell us any of this?" Jazz asks.
"Well at first we didn't want to risk Phantom overhearing and taking offense. By the time we had the sweep shield it just... slipped our minds. You and Danny were both so uninterested in ghosts by then and... I suppose it never occurred to us how things might've seemed from your perspectives," Maddie answered, leaning against Jack's side, both looking contrite.
"What, that our parents were genocidal maniacs hellbent on torturing and experimenting on people?"
Danny mutters it under his breath, but in the otherwise silent room it practically echoes.
The two look stricken, eyes tearing up. Maddie covers her mouth with a hand and clutches her husband with the other as he hugs her.
Jazz winces, but only nods, damningly, when they glance her way.
The litany apologies and hugs that follow leave the children a mixture of relieved, embarrassed, and resigned - though the last seems to be aimed at their parents’ assurance that they will “give them regular updates on their research goals and progress from now on.”
I have been simmering this plotline since the post went up like two days ago
Part 2 incoming tomorrow or the next day most likely, this is only a fraction of the extent to which my my has been triggered, but I got IRL Obligations (bleh) & I don't want to lose my place so I'm just posting this for now
