Summary
So...it's another time travel Naruto story...
Anyway...
The future sucked ass. They watched all their loved ones get horrifically murdered by a psychopathic rabbit moon witch, who then turned the world into a dried-out grape(which is a raisin if you didn't know, you heathens) by sucking all the chakra out of it. Of course, they kicked her butt into another moon(that had been fun) but the world was still fucked. So with nothing left to do and nothing left to look forward to, Team 7 (minus Kakashi -rip man, fly high!) decided to look back, as in travel back into the past.
They had trauma!
They had anger issues!
They looked like dead people!
Naruto, Sasuke, and Sakura are going to fuck up the past so bad that the future is going to look like a paradise!

Summary
Midoriya Izuku has passed through life on auto-pilot. He didn't have much and his life was crap so what was the use. He never yearned for more, he never strived to anything until...someone decided to give a shit.
Uraraka Ochaco has moved countless times since her birth and can never keep a friend. After a while, she chose not to make any in the first place, knowing that she would leave them sooner or later...until a small green-haired boy with sparkle-filled eyes and rare smiles came into the picture.
Fate seemed almost too excited playing with them.
Will things turn out the way they want or will it burn to the ground?

Visiting The Arcade by crossing_boundaries

Summary
Being yanked from your daily life to the abyss by an angel-looking reject that makes you question your sexuality was not what the students and their teachers at U.A expected to happen right after the Sports Festival.
The unknown going by the name Exceed plucked them out of their timeline just to see what would happen!
Finding out there is a multiverse and being forced to watch alternate versions of themselves, while being isolated in a pocket dimension called The Arcade sure sounds like fun -note the heavy sarcasm.
With no way out and their quirks reduced to nothing. What are the students and teachers of U.A going to do?
Watch the multiverse!
Secrets are revealed.
Opinions are changed.
People will riot.
Exceed is shifty as hell -no one trusts them despite the typical Tsundere personality.
Holy shit...will the universe survive the chaos that is U.A and its students?
HIATUS ((I'm sorry(╥﹏╥)): Check the notes at the end of the Chapter 8 for more info.

Summary
When Dick Grayson accidentally portals into the past, he finds himself on the Justice League’s Watchtower surrounded by younger versions of the original members of the Justice League...including Batman.
But none of them have any idea who Nightwing (or even Robin) is.
What a perfect opportunity to create a little chaos...while also trying not to break the timestream.

Summary
Jason was warm, still, and Dick clung to that most of all. There was a first aid kit beneath Jason’s sink. It had taken Roy telling him about it for Dick to find it. He still couldn’t see straight, a concussion, maybe. Or just the tears.
Jason was warm, but his blood was hot, soaking through the wad of toilet paper Dick had pressed to his wrist in desperation.
“He’s,” he said, hiccupping. “He’s still bleeding, Roy, I don’t know—”
“It’s okay,” Roy said, voice tight even as he tried to sound soothing. “I already had Mia call 911, they’re on their way.
Dick nodded. Then he remembered Roy couldn’t see him. He tried to speak, but all that came out was a choked sob.Or: Dick and Jason angst with a side of established JayRoy because I hold all the power here

Bookmarker's Notes
They watch, and Dick wonders if he is doomed, like Bruce, to look on forever, as people leave. If there is someone out there, with whom Dick could fight, and laugh, and cry honestly, with whom he might disagree without it tearing the very world apart. If he can ever love without hurting or be hurt in turn.
Kiss my wings, though I refuse to fly

Summary
Jason keeps finding ghosts of himself in other kids.
And can't really seem to escape this whole magic thing.
Or the whole dying thing.
(And time does not wait for you to get back on your feet. Or your head screwed on straight).

This was everything 🙌. I love when authors explore Jason's magic background. I love the inclusion of Constantine and his relationship with Jason. I need more of this ASAP.

Summary
“Tony,” Tony says, “Stark.” He watches the kid’s face for any hint of recognition but there’s none.
“Hence why those guys want you to build a Stark missile.”
“Right.”
The kid snorts, “what, do you work in R&D at your own company?” When Tony just gives him a blank look he clears his throat, “nevermind. So if you can build a missile I bet you can figure out a way to get us out of here.”
Tony sighs, turning his face away. He’s so tired. “I can’t build them that weapon, kid.”
Now it’s the kid’s turn to look confused. “Then build something else,” he says simply.
**
Or, AU where Dick Grayson has an unfortunate run in with a wizard in Gotham City and finds himself tossed across the multiverse to a cave in Afghanistan with a billionaire who hasn't gone through his self-improvement journey yet.
