Tsuna doesn't know how he dies for good, only that he still has regrets when he does. When he wakes up, he's in the body of Sawada Nana, mother of a 2 year old Tsuna, and those regrets become tenfold. He's drowning in the implications, when an Arcobaleno appears on his doorstep, and the future becomes infinite possibility.

Unwillingly forced to serve as a human trial for a crazy alchemist experimenting with time travel, Edward Elric finds himself standing across from Truth in the moment it takes his leg from him. Armed with the knowledge of what's to come and burdened with guilt for the choices he'd made as an adult, Ed sets out to fix every mistake he ever made and save every life they ever lost, no matter what it takes.

Fate has always had a love-hate relationship with the members of Team 7, and Sai is just now realizing that's he's most definitely not exempt.

The first person Kakashi meets when he staggers out of the house, covered in blood, is Uchiha Obito.

“Oh my god,” Jiraiya says, staring up at the ceiling.

“Wade and I have a tradition whenever one of us turns out not to be dead.” She smiles at Cable politely. “Would you like to stay for dinner?” “And by dinner, she means bare minimum twelve hours of the most animalistic ravaging of each others’ naughty bits that you can see outside Bangkok, big boy. Really putting the freak in fan-freaking-tastic multi-orgasmic cum-marathon.” “So what do you say?” Cable grinds his jaw for a second, but honestly, who would pass up these A-listers? “Why the hell not?”

Tobirama loved Itama enough to go against the natural laws in an attempt to bring him back. For Itama, it’s time to return the favor.

"Zewu-Jun. You once told me about a house surrounded by gentians, where you visited once a month, and how Lan Zhan still waited there, even when the door no longer opened." Xichen feels light-headed. He feels shocked, and angry. He has never told anyone such a thing, but Lan Zhan is giving Xichen a look of utter betrayal. "You told him?" Lan Zhan whispers. "When?" Wei Wuxian takes Lan Zhan's hand. "About twenty years from now." Wei Wuxian starts again from the beginning.

When Mace joins the 212th on a dangerous world, it's meant to help them end the campaign there more quickly. But his presence there sets into motion something that started a thousand years ago, and won't be stopped so easily.

Agen Kolar is many things, but prepared to play babysitter for a repentant Sith is definitely not among them. However, Vader holds the keys to a conspiracy that could bring down the Jedi, and in light of that, Agen has to make allowances. (Anakin Skywalker just wants another chance. One more chance to make the right choices this time around, and save the galaxy he once destroyed. And if a weird, surly Zabrak Jedi Master with a penchant for punching people and a talent for finding trouble can help him, he'll take it.)

Aka Darth Talon, Arla Fett, and Xanatos break the timestream. It isn't the worst thing that could happen.

Fox has the galaxy’s greatest hero in his bed, he’s well-fed, he’s astonishingly well-rested, and he has a whole week of leave saved up that starts in about six hours, during which no one is allowed to bother him with anything work-related even if Coruscant gets invaded by brain-stealing worms. Again. He made sure Thorn and Thire both knew that. Which makes it ten times as unpleasant to wake up to someone bypassing the chime entirely and just pounding right on his door.

In the middle of her grief over Alderaan's destruction, Leia manages to hurl herself, her father, and her twin brother back to the start of the Clone Wars. It's not an opportunity any of them are about to pass up.

After dying on the Death Star, Obi-Wan Kenobi expects to; well, die. Instead, he wakes up in the initiate dorms at the Coruscant Temple. The Force has sent him back in time, given him a second chance, and he knows what he needs to do. At twelve years old, his life is at a crossroads. Does he apprentice to Qui-Gon Jinn or does he join the AgriCorps. He knows the fate of the galaxy if he chooses the former and so he dedicates himself to the latter. Only, the Force works in mysterious ways. When a third option is presented, becoming Yan Dooku's Padawan, Obi-Wan has to make a decision. With a new master and a new chance, Obi-Wan is determined to save the galaxy from Sidious's plans for it.

When Cullen finds himself back in Kirkwall he's faced with several questions. Who should he tell, what should he say, and how is he going to fix Kirkwall before things get out of hand. Again. Time-travel fix-it where things go better but not great, because it's still Kirkwall after all. Alternative title: The real treasure is the friends we make along the way (and the slavers we kill with them)

Margaery goes back in time. She marries a Baratheon. Again. This time, she’ll make it stick.

What would Game of Thrones have been like with a strong, empowered Sansa?

Waking up two years before their adventure even began was a surprise. The Straw Hats have to find each other again and make their way back to the New World and their dreams. Dealing with younger, weaker bodies and the weight of future knowledge they will find it's not as easy as a simple do-over. Every change has an effect on themselves and on the world. This story will quickly diverge from cannon. It will mix up, move around and ignore entire arcs. These guys are not looking for a boring adventure when they already have answers. What's the point in doing it all the same?
