#he doesn't understand Danny's half-dead explanation

Danny Phantom x World Trigger

So what if the portal in Danny basement didn't lead to the Ghost Zone but to the Neighbor world? This could work considering I've seen lots of ideas that the Infinite Reals isn't stagnant and that the haunt doors move (I don't know if this is confirmed in the DP canon) and it's canonic that the different Neighbor Worlds move in a wacky sort of orbital system. This would make the ghosts Neighbors who are trying to yoink people for their own respective societies. Maybe the trigger that is allowing the void travel is very experimental/deadly/top-secret which is why other nations aren't using it. Or maybe other nations consider the idea foolhardy and something that would never work so they don't try it and actively shun the nations that are trying it. There's also the resource management/intensity that you could think about. Many ways that you can spin it so that the small regulars of Danny's rogue gallery fit within this explanation. In fact, you could have a handful of Neighbor nations separately come up with the idea if you want to have "in-fighting" within the Gallery (again, I don't remember if this happened in canon). Maybe some of the Gallery eventually move into Amity Park and become unofficial citizens.

In this case, the Fenton tech probably isn't based off ectoplasm, but trion. Whether or not Jack and Maddie are aware of this fact is up to you. I can totally see them stumbling across a trion soldier, defeating it with Fenton wacky logic and then completely mistaking it for a ghost instead of an alien/otherworldly entity. Maybe they saw one of their friends get taken by trion soldiers and that's what started their obsession. But this means that there are a few triggers laying around the lab. Maybe Danny and Jazz have been trained in a few of these triggers and have some that are highly specialized to them. If so, assuming that one is going with the "half-dead" thing that makes Danny a halfa, then maybe he has his on him and he makes a black trigger out of his death. Granted, this feels like a stretch in plausibility so one may or may not want to include it.

Now because of the long standing, open portal to the Neighbor-verse, more trion expeditions from other nations probably pop up around Amity Park when compared to a place that doesn't have it. This makes Amity Parkers really experienced with what to do when that happens. Maybe they start to believe the Fentons. Maybe the Fentons or the Undying Trio start to give out basic triggers and train them in how to use it. For example, if a Bamster comes through, then the Amity Parkers immediately form groups and go into smaller areas while also doing head counts on some sort of public server. But a Marmod makes them scatter in pairs or maybe groups of 3-4 at the most. The overall affect is that there is a tight bond between Amity Parkers. One moment, the A-listers could be bullying others and the next, they're all working together to get to safety. I imagine that it affects the younger citizens more than the older ones, but that's just me.

With this, you can also decide how or if you want any characters to have Side Effects. One could have Danny have something like Chika's and have him have a danger sense that changes as he grows. So a Marmod would set if off strongly when the portal first opened but maybe after half a year or so, it registers as a medium or low threat to him. Maybe Dash has enhanced strength while Paulina can affect how others perceive her to a degree. Maybe Sam can talk to plants while Tucker has a complete and total understanding of technology.

As for how this ties into the main series, it would likely come into play after the Aftokrator invasion. Osamu pushes Border into an uncomfortable position for them. With the Away Mission coming up and many of their heavy hitters leaving for it, they want to make sure that they're not left completely defenseless should something similar happen while it's happening. So they look to outsource (with a huge blow to their pride). Now when Neighbors became widespread knowledge, the US Government tried to "recruit" Amity Park. However, they rebuffed the government multiple times including and up to the present. Whether or not the GIW came about as a way to strong arm them before or after this is up to you. When Border reaches out to them, the US Government doesn't really want to give them resources because the US likes to hoard weapons. So they direct Border to small town Amity Park which has been dealing with Neighbor attacks for a while yet has a very small casualty rate.

The Border goes to investigate and try and recruit. Their success depends largely on who they bring. Old Border members are much more likely to have things go over smoothly, bonus points to Danny if Yuma is brought along. But if it's just New Border agents, then it's going to end with Border not getting any help from Amity Park with the residents being mildly antagonistic to them. Danny would go out to meet them because while the Mayor may make big decisions for them, being the main protector makes his opinion valued. If the Border mentions the fact that they are gaining temporary protectors for the Away Trip, Danny is going to consult with any of the Rogue Gallery that has moved to Amity Park and/or Team Phantom. If Danny has Danger Sense, it would be a great show of power to Border if an attack comes through and he just sighs and sends out an alert. It would not only show that Danny has a "powerful" side effect for Border, but it also shows just how normalized attacks are and how most people go about their day through it, which is mind-boggling to Border who has shut down an entire area because of Neighbor attacks.

If Border passes the trust test, then Danny would probably ask about which Nations they're going through. He would casually throw out names and be like "well so and so is a small nation so they're less likely to have people but this nation is getting bigger so they might have some new captures" which would reveal just how valuable Amity Park is as an information source if not a defense ally.
