crossovers that actually work
All too often, crossovers are poorly executed and/or clunkily fitted together. But every once in a while, they work. They really work. This is a collection of those crossovers.

Summary
Just a few little oneshots surrounding crossover ideas between Stranger Things and Umbrella Academy. Mostly (so far) about El, Five, and/or Klaus in different situations/encounters with people from either world. If I find enough inspiration (and if enough people like the idea), I'll probably make a longer version of some of them.
Chapter 1: Rather than the Demogorgon, Eleven encounters Five in the Bath, and together they become a little less alone.
Chapter 2: Eleven can astral project to an extent that transcends her own dimension. Klaus just believes 'Ellie' is a ghost. They become best friends.
Chapter 3: Five finds himself in the Upside Down. He and Will, another unfortunate soul, learn to survive together.
Chapter 4: The Hargreeves stop the apocalypse the first time around, and the Byers-Hoppers decide two rounds with the Upside Down were two too many. Five meets El and Will at school. They've all got problems of their own, but they help each other through them.
Chapter 5: Max is new in town, and Diego just wants to escape from time to time. They end up meeting and (begrudgingly) becoming something like friends.Series

Summary
They say when you assume you make an ass of you and me.
Matt wishes that the Avenger's assumptions about his seeming inability to read the written word did something as benign as making an ass of him and them. Being called illiterate shouldn't hurt, not when he knows he's not, and it's not like he can tell them the truth.
Not that the truth would make much difference. He's just going to have to grin and bear it.
If he can.

Summary
She is born from fire. Strange, isn’t it, that a creature of ice needs a fiery soul, but the creation of familiars has always been a right of passage and trial by fire for the jotunn. Loki has always been a little unsure of the process, because he is no more jotnar than he is aesir, and the frost giants hide their secrets well.
Or, Loki meets his daemon. She is not what he expects.

Bookmarker's Notes
“So what does that mean, unmaking?” Loki wonders. He paces, suddenly full of a restless, desperate energy.
She watches him through hooded eyes. “Tell me, dear one,” she says. “Does Loki the Prince still exist?”
He looks down at himself. His fine clothes are dusty and torn, and he has lost what little weight he had. He is too pale to be Aesir and the markings of a giant mar his skin. He can feel the shadows under his eyes, and the wildness gleaming there. He has a familiar, a daemon.
“No,” he says slowly. “I rather think that he has died.”
“Does Loki the trickster still exist?”
No, because he has not played a harmless joke on a soul in half a millennia.
“Does Loki the coward still draw breath?”
No, because he does not look behind him now (he has no need, his soul walks beside him) and he does not shy away from violence.
“Does Odin’s son? Does Laufey’s son? Does Thor’s brother?”
Loki considers all these bonds, known and unknown. “No,” he says. “I have broken them all.”
His daemon bares her sharp, dripping fangs at him. “And what is Loki now?”
He thinks on that, for a moment. “The rightful King of Asgard,” he snarls. “The liberator. Yours.”
She laughs again, drapping around his shoulders. “You see,” she says. “Ragnarok. The weaker self has passed away, and from the ashes, something transcendent has arisen. The story has begun anew.”
He likes that word. Transcendent. His familiar takes the shape of a bird, a Midgardian legend, red and gold-feathered with fire trailing her flight. She circles him once, twice, a light in the crushing darkness, and drops back to his shoulder in feathered serpent form again.
“We are more than what we were,” she hisses. They are not whole, not yet—most likely not ever, because those bonds, once cut, do not easily repair—but she is his and he is hers. They belong to each other.

“You want to tell me what that was all about?” Gideon asked. He sat opposite Dean while Reid looked on apprehensively, the tension in the air palpable.
“No.” Dean was obviously upset, making no attempt to cover it.
“What ever it is,” Gideon offered with genuine concern, “We can help you.”
Dean laughed until he cried.

Tony falls through the space between worlds. As a result, he can see daemons. It kind of freaks him out. (It's stranger and more beautiful than he could have ever imagined.)

Bookmarker's Notes
“You’re not an animal,” Tony tells the cat one day, when they’re alone in his workshop with bits of the armor scattered around them.
“No,” agrees the cat. He’s amused, Tony can tell. He can tell a lot about the cat, these days. They’re growing closer together.
“But you’re not my soul either. Not all of it, anyway.”
“About half,” the cat agrees. “A little less, since Afghanistan.”
Six months ago, Tony would have laughed and thrown the damn thing out the window for daring to suggest that it was part of his soul. Now, though. Now, he’s seen the animals die, go up in dust the moment their person breathes for the last time. He’s seen them follow into fire, through knives and bullets and crumbling buildings. He’s seen them yell and fight with their humans, and seen them love them unconditionally.
They are souls, or part of them. The cat is part of Tony.
The cat blinks, languid, amused. And then, Tony gets it. He smiles. “What do you call yourselves?” he asks, and the cat shows him a row of tiny, snowy white teeth.
“Daemons,” he says, tail curling. “We call ourselves daemons.”

Summary
Once upon a time there was a girl and a demon.
The girl’s hair was the color of Dust, a gleaming gold, and with it shining in the wind she lifted her sword, and drove it straight into the heart of the demon that had tried to call her little village its own. The people loved her. They say her soul was a brilliant white dog, a guardian, large as an ox. He grappled with the monster. With his fur a light to drive it back.
And so time turned on. Technology improved. The people lived. A thousand years passed. A kingdom grew, the loyal mutt-souls of the common people protected by the noble lines of knights, bloodhounds and shepherds and retrievers. Happily ever after, right?
Tsht. Yeah. You know, they say only dogs get happy endings.
(A Nimona daemon AU: in which Ballister's daemon changes shape, impossibly, the night of the Queen's murder, and this is of some interest to Nimona.)

Bookmarker's Notes
“Have you ever thought about why everyone is a dog? About why you never see anything else?”
“Daemons are dogs,” Kiran says. Her voice, much quieter than Nimona’s, somehow gets the girl to go entirely silent, her cat-chest heaving. “They can’t be anything else.”
Nimona shrinks down into a pink-and-white feathered bird, her neck-feathers iridescent in the grimy light. “Oh,” the pigeon says, “so you turning into a pigeon was a mistake, then. That never happened?”
“That’s—” Ballister starts, but he’s frozen in place, because it was Kiran, but he remembers how it felt. The way she was illuminated by dying sparks. The way wind tugged at feathers, different than it ever did at fur. The sky, and how they could not see it. She could’ve flown. He didn’t want to leave the ground.
“Different?” Nimona flaps her wings. “Yeah. No.”
It is getting, Ballister thinks, harder to ignore.
Kiran’s paws twitch.
He says, “Gloreth was a dog.”
“Yeah. Uh-huh.” Nimona rolls her eyes, drawing her wings back in close. “So some girl a thousand years ago gets to determine the course of your life for the rest of, what, forever? Boss, think about it. What do dogs have that nobody else does?”
He’s humoring her. That’s all it is. Nimona is—better company than he thought she’d be when he first met her, but he’s not—her. She’s made that obvious enough. He has no idea what she is, but…this is his city. He grew up here. And sure, it has flaws, but…they can be fixed. He was trying to fix them. And he could’ve. He just—if he can get Ambrosius on his side, get rid of the Director, then…
“Loyalty,” Kiran says, lifting her head. Her large eyes stare at Nimona. Pigeons are small. Even Kiran’s bigger than them. “Dogs have loyalty.”
“Unquestioning loyalty.” Nimona shakes her head. “You can’t do this shit with cats.” She flicks into a cat, bunches up her muscles and leaps onto his shoulders, teetering, somewhat. “People hate cats for doing their own things. They shoot ‘em. With a sword!”
“Nimona,” Ballister says, as she climbs atop his head, “I have never in my life seen someone shoot a cat. You don’t even shoot swords.”
“It’s a metaphor, boss.” Nimona flops across his head, her tail twitching, dangling. “You guys aren’t cats because this bullshit doesn’t work if you’re anything else. Birds could fly. Oxen could stampede the place. Don’t get me started with the wild animals. But dogs—dogs are good, aren’t they? They’re just so good. They do what they’re told, and they’re happy the entire time. Who else would you send after monsters?”
