#the reason i added deaged ellie possibility is because i want to see damian panicking at the idea that his brother became a teen dad

Demon Twin AU but Damian has been seeing ghostly visages of his twin slowly growing up with him

So, the Danny Damian Twin AUs! They're fun!

But what if, when Danny fakes his death/is killed, he actually dies and becomes a halfa as a kid? Danny because he is Danny, has the great idea to live a double life upon figuring out he can be both ghost and human!

As a human, he goes to America where he gets adopted by the Fentons and live as Danny Fenton

I headcanon that halfas are very adaptable and basically get powers according to their needs. So he figures out how to portal.

As a ghost, Danny stays around Damian and helps him out. Sometimes he slips up and Damian sees Phantom right next to him.

To Damian, this is the Pit Ghost of his brother who has come back to haunt him, made even worse when he realizes that Danny is also growing exactly at the rate he was despite being dead. He thinks that Dannys last wish was to grow up with Damian that's why he's doing that.

It gets even worse for Damian when he realizes the ghost of his dead twin brother has been helping him invisibly the entire time and it's possible that that's why Danny's staying around

Now, I need you to picture one of the Batfam seeing Danny

Imagine them asking him about it

Imagine Damian having to explain that the ghost of his dead brother sometimes accompanies him

Of course, on Danny's human side of things, the Fentons finally made that portal and he has to take up being a hero in Amity Park. Meaning he has less time to look over Damian.

What does this look like to Damian?

It looks like his brother is fading away slowly because Danny's decided Damian is now in a safe place

This all comes to a head when Danny disappears for a long time, long enough for Damian to think he's gone gone

And then Danny comes back and he's injured or maybe he has a baby Ellie and for the first time in years actually talks to Damian and asks for help

I could imagine the mental angst of Damian seeing his ghostly brother being with him, and once he started getting to get better vias forced therapy and socialing in the batfam, its going to destroy him like a full train wreak the moment his ghostly twin brother disappeared completely one day.

Like he gotten used to having his brother with him, protecting him from harm during missions so easily, easy to talk to about the batfam even if he couldn't hear danny, shared secrets and moments and their birthdays together, but by the week after his brother's ghostly form disappeared completely from his side would be like a bomb ticking in Damian's mental state, until the during one of the patrol when he actually gotten hurt during a fight, and by the time he come back to the Wayne Manor, getting healed up at the medbay to his own room..

He going to have the most terrible agony meltdown of his life, by the time the batfam rushes to checks on him, his entire room is a wreak that seem like a 4 level hurricane went through it with Damian in the middle of the room literal screaming, crying to the point of hyperventilating hugging himself because he has nothing physically left of Danny now.

He only know now that his brother was fully gone, or went to the otherside but He still needed him, he should've been here with him always,.. forever like they promised.. but now..

Now he was truly gone..
