#it would also give away the fenton's trick and dont want to reveal that before the agency has been stopped

Good reveal au, where after learning phantom's identity and realizing the atrocities that the GIW have committed (or alternatively, ethical science au, where they find out the GIW plagarized them), the fenton parents decided to create the 'ultimate ghost-ending weapon' and sell it to the agents.

They go absolutely overboard, describing to the agents in meticulous detail how it evaporates any ghost it hits near-instantly and describing it quite ruthlessly in the blueprints, and soon the GIW have raplaced all their main weapons with the new gun.

Except it doesn't actually kill ghosts. It's the Fenton Bazooka. You know, the one that creates a portable portal to suck the ghost back into the ghost zone? What they actually did was retool it slightly to make it look more grusome than it actually is. They even added a beacon in Phantom's Keep, which all Fenton Bazookas will target when they open a portal, so the ghosts are always delivered to the keep.

From there, Phantom stationed an emergency medical team at the keep to treat the many injured and ragged ghosts that the GIW 'destroyed,' and to explain what just happened.

What they didn't anticipate was that now that the GIW have a mass-produced weapon that they believed would effectively eradicate ghosts, they would go on the offensive. They have a number of cities they've been monitoring but didn't want to get involved in without better tools.

One of those cities is Gotham.

And the Bats are ectocontaminated enough to register as ghosts.

Batman witnessed several of his children get evaporated by green energy weapons within mere moments of each other. He's absolutely gutted. Devastated. They didn’t even stand a chance.

He'll get his revenge, and it's frighteningly easy to track the weapon to private subcontractors. The Doctors Fenton, in Illinois. Their research calls for the genocide of all ghost kind, and apparently, that war started by killing his own children.

His children will not die in vain.

He gets to Amity Park and finds the Engineer's Nightmare of a building that is Fentonworks, but that night, before he can hack through the security and break in, one of the windows opens.

It's one of his kids that he had watched evaporate before his very eyes. They give him a silent signal of one of their identifying security codes and gesture for him to come inside.

Is it a trap? A prank in poor taste? Utterly genuine?

He goes through the window.

All of his dead kids are there, wearing borrowed pajamas and only their dominoes to conceal their identities. Daniel Fenton (son of the Fentons, this is his bedroom, has voiced a few arguments against his parent's views, but still an unknown) is among the crowd of teens and young adults, twirling on an office chair and obnoxiously sipping a capri sun.

"First thing you need to know, Bats," Daniel says after finishing his drink, "is that my parents are absolutely NOT genocidal ectophobic scumbags, and that is the reason why your kids are still alive."
