Questionable Questing

Danny doesn't realize his Ghost self is defiling and dominating his sister and mother because he'd have to accept he wants to do that and would. Which lets his Ghost run wild among other acts done to help them both. Danny has to figure out the Ghost is part of him before he can start having knowledge of what it does.

Have it so he has minor ghost powers from the portal and him and Sam and Tucker are hunting Ghosts without understanding how big and terrifying a Ghost Danny is hiding from himself.

How do his family members feel about it? And why haven't they confronted Danny over it yet? Or at least tell other people?

Jazz and Maddie think they are having bizzare nightmares and are being conditoned into not quite remembering what is happening to them.
While Jack and Maddie and the rest did tests and they think that Danny only has minor ghost powers and isn't a full ghost hybrid.

Also, rewatching dark danny. I love the character design and voice, but what woud a actual dark ghost Danny be like? Based on him and not a weird fusion of him and vlad's ghost

Horney dreams that may or may not be real are a staple of many hentai plots. But with Ghost Danny I guess it depends on how metaphysical you want to get. You could go full silent hill and create a monstrous form that represents his inner demons? Or just go with a generic superhero costume change? And anything in between.

I think a corrupted superhero form. Something punk rock?

I know Danny wants to be an astronaut. Maybe some kind of space/ghost suit with eldritch magic mixing in with technology. Hard to describe but I have a specific image in ind.

Do share

I was kind of thinking you take the Dead Space armour, the one that looks usable yet very heavy and metallic, and you combine that with some of Alien's biomechanical design work. Like this.

Although this more monstrous from would definitely be something only used for attacking and not seducing family members. lol.

No hotlink allowed for image

Oh that stinks. Here's a reddit link. Can't go wrong with, right? If not just look up Jockey scene from Aliens.

Anyway I sleep. Night. I'll think more on this alternate form and see if I can come up with something more suited for Porn instead of cosmic horror. lol.

Yikes

Got that suited for porn image and girls being bred pregnant by alien monsters pics? Also, do you want the Danny idea? If not I have a Doom and Dead Space combo idea to shard with you at 11 based on it

I'll look around for some alien pic's. But a Doom idea? That setting is underutilized in fanfiction. It's actually very sad.

Got aliens breeding girls with monsters pics?
Read update if you may and research station on a planet.

There's a portal into Ghostzone/Hell our Danny is caught up in it and from there everything descends into madness while in trying to survive Danny lad starts to figure out he is one of the greater monsters.

With the grand conclusion of this story being in the end our Danny does resolve to be better but at the same time accepts turning the research station into a haunted nightmare world fuckpit he rules over with some ethical limits he develops into a code. This idea was inspired by you mentioning the Deadspace astronaut suit concept. However if you were to use a proper Danny Phantom idea yourself I'd drop this.
