Summary
“Hwha-what…?” Blearily, Edward cracked open his eyes, the delicate movement causing microscopic specks of sand to tumble from his lashes. He could feel the grit crunch in his teeth and stab under his fingernails. His hair, which was tied back in its usual braid, was pulled loose slightly and he was certain that every strand held a piece of dirt. Despite the intense heat, Edward could sense he was in someone’s shadow, and that alone livened him up.
"Kid?" Vash shook Ed again, and like a rug that hadn't seen a good cleaning sand flew off of the boy. "Oh! You're waking up hey, hey!"—✦❘༻༺❘✦—
Two worlds collide in this anime crossover, roleplay-turned-novel! When the Elric brothers are transported to No Man’s Land, they’re rescued by Vash the Stampede, an eccentric outlaw with a bleeding heart and a bounty on his head. With the Elrics’ alchemy turning heads, trust and courage are put to the test in more ways than one in this tale of two brothers… or four brothers?
Two sisters wrote this so…🤭

Summary
So… Enjin knows himself, and he knows he is not someone suited to dealing with children.

And yet, through a series of unforeseen incidents, he ends up becoming the babysitter of the youngest member of the Akuta team.
OR; Rudo turns into a four-year-old child.

"Wait---you have flames too, and they're blue?" Ace stared at Touya, his mouth agape.
Touya rolled his eyes and turned on his heel to walk away from that grinning, freckled face.
"Wait for me, aniki!"
Or,
Touya Todoroki gets a second chance at life when he is transported to the world of One Piece.

Summary
"I remember every night since the dawn of my existence… and I can assure you, Marc Spector, you are more lost than you think"
"Can you quit the games and just answer me for once?"
"The only answer I can give you… is that you are not in your universe"
"What?"˚࿔ ⋆⭒˚.⋆˚࿔ ⋆⭒˚.⋆˚࿔ ⋆⭒˚.⋆
Marc was no stranger to losing track of time; it was a direct consequence of sharing his mind and body with two other "people," but waking up in a completely different universe with no explanation...
Yeah, that was new.
With no ID, no money, no home, or anything else needed for a decent life, and a group of vigilantes who aren't too fond of another vigilante—especially one dressed in white who seems to have a few issues of his own...
What could go wrong?

Summary
In hindsight, facing off against Thor and Odin would really have been a better move than falling into the abyss. Dying would have been his first choice, but as his track record showed, Loki didn’t usually get what he wanted.
AKA: When Loki falls from the Bifrost, he lands in Truth's domain instead of Thanos'.

Summary
Tim knew today is going to be wild. Batman, Robin, Nightwing and Superman were fighting one of Luthor’s monstrosities in Diamond District. He thought he was prepared for everything. The new long-distance lens for his camera came just in time, he finally managed to find a pair of comfortable sneakers that wouldn’t fall apart after an hour of roof-crawling and it was still early enough that he could reach the school’s administration ahead of time.
As it happens, he hadn’t prepared for stumbling across an amateurish occult summoning that nonetheless appeared to be working.

Summary
Dottore never bothered to deny that he was the villain. It was a role he knew well, and one he had never felt the need to question.
When an accident takes him to a world where Quirks are part of human nature and heroes are revered as symbols of peace, he finds a society fascinating for a very different reason: its rules and technologies are new.
As he studies this world and searches for a way back home, Dottore begins experimenting with what makes it different from his own. Quirks, the human body, the energy of this world… everything can become knowledge.
But his presence does not go unnoticed.
Between heroes trying to understand him, villains who see an opportunity in him, and experiments that begin to slip out of his control, an anomaly starts to alter the course of events.
After all, what happens when someone who has always been accustomed to being the villain ends up becoming one of the greatest problems hero society will ever have to face?
