I'm an Undead something by CosmicDustPoltergeist

Summary
Danny is just trying to survive his shitty afterlife in peace at this point. He was forced to leave his home dimension because the anti-ghost sentiments spiraled out of control, and before he knew it, nukes destroyed or poisoned everything and he was the only one still alive. After fighting his way back to the Infinite Realms, Clockwork to send him somewhere he can heal as he grieves.
Gotham is not what he expects. The city spirit is tearing itself apart and Danny doesn't know how to help. Danny may have had a panic attack when he notices the changes to both of his forms and the colour difference of ectoplasm in this dimension, but on a humorous note, he finds out that the locals think he's a vampire. He figures that it's close enough to true and doesn't correct them.
It's all fun and games til the local vigilantes find out about him.
--------------------------------------------------------------------------------------
This is loosely based off of someone else's au where Lady Gotham makes ectoplasm red to fuck with Danny and my own post of Danny's forms swopping hair colour as Danny's human hair grays out with age and/or stress. -

Summary
Lucifer drags himself away from the aftermath of s2 and is not coping well with his new normal, but this time people notice the King is falling apart. Apologies are made, buried traumas are unearthed, and healing begins one step at a time.
------------------------------------------
Charlie starts out in a negative light in this, but she won't stay that way, promise. She's just needs consequences and I NEED Lucifer to have a mental breakdown/crash out. So this is going to be cathartic for me as much as a character study piece. -

Summary
Danny was Athanasia Al Ghul, the twin of Damian Al Ghul, but because of his sex he was dismissed and seen as lesser. A crime he is murdered for, but when he's placed into the Lazarus Pits, they decide to keep him. Two years later, a feral "little girl" is found just outside Elmerton and promptly adopted by a red haired girl who was on a day trip with her parents.
Years pass, Athanasia is now the young man he was meant to be, his adoptive parents accept him completely and have since adopted his clones/alternate self, and Jazz is prepping for college when the Justice League finally decides to investigate Amity Park because a government branch is attacked daily there by the locals. No one is happy to see the JL, especially Dan and Danny who recognize Damian on the spot. They are not happy to see their twin turned older brother, while Damian mourns the relationship they never had.

His obsession is MINE now by CosmicDustPoltergeist

Summary
Loosely based off someone's post (couldn't find who's) on What if Dan got Vlad's obsession involving Danny instead of his revenge one, so when he goes back in time he doesn't try to kill everyone and instead worms his way into the Fenton's lives and proves they're bad parents and adopt Jazz and Danny. He then works at/maybe owns a bakery.
I know very little about working at a professional bakery, so I'm changing that to a coffee shop since I know more about that.

Summary
When things turn sour in their home dimension, Dan, Jazz, and Danny try to escape into the Ghost Zone and end up blasted into a natural portal. With no reason to try to go back, the siblings decide to make a new home. Unfortunately, they do not have the plot armor they once had in Amity Park, so anyone with any sense can tell something ain't quite right with them. Even in human form, Danny reads as other, Jazz seems too odd to be only-human raised, and Dan forgot what being human even means.
Luckily, this new dimension is used to aliens crashlanding and winging their stay. The lovely people of Smallville in particular are always willing to lend a helping help to their unearthly guests. They could end up being wonderful protectors, like their sweet Supers. Does Clark really think his hometown can't recognize him? Or piece together his cousin, little brother, and son are Supergirl and the Superboys?

Summary
Lucifer is very aware that certain aspects of personal grooming tend to go out the window for him on bad days (or weeks—or months). He does his best to keep up with it—he really does! It's just that the more visible things like his hair and clothes get priority, and by the times he realizes what a disaster his living space has become, or even worse, his wings...
Things were easier when he was living alone and there was nobody else around to notice things like the powder down that he scatters all over the place when he hasn't preened himself properly in too long. At least, they were until someone reaches out a helping hand.

Summary
Lucifer asked the question to Lilith and she lied. It’s because of that lie that every so often he would find himself with no energy to keep his actual form so he would just wake up as a creature that no one really likes or loves. He’s finally trying to move on with his life, to move on from Lilith when he wakes up one day as a worm.
Lucifer panics but Alastor takes care of him without Lucifer having to say anything. So what happens when Lilith comes back and tries to act like they can be a perfect family?
Heaven preached that Hell is forever, why can’t love be forever as well?

Summary
It was mostly quiet between the two of them for a long moment. The only sound was Lucifer soft sniffles and the soft jazz music that Alastor was playing from his staff.
“There's more, isn't there?” Alastor asked. Lucifer feels Alastor's hand fall to the small of his back and rub his thumb into his back.
Lucifer pulls back from Alastor hold. He uses the sleeves on the pink sweater to whip his eyes.
“I'm supposed to be stronger than this.” Lucifer lets out a bitter laugh, as he lets his hands fall to his lap. “I'm the king of hell, for fuck’s sake.”
“You are allowed to feel hurt, Lucifer.” Alastor says. The weight of his hand falls onto Lucifer's shoulder, making his eyes turn to look at it. “Even Kings bleed.”
~~~
Or Alastor crashes out on Charlie for not apologizing to Lucifer and leaving him in such a mental state for days after the battle with Vox.
