You didn't add it so I'll only answer this ask since it's about the same thing.
So! Fic recs! I'm only gonna share 10 fics for now but I hope you like them ^^
Time wears the mask, and is consumed by the Fierce Deity. The rest of them try to cope with the overpowered stranger in their midst. Linked Universe fic.
Time knows well of the split in time he had caused, the branching paths of his legacy. The world flooded with water or twilight, his successors in the sailor hero and the humble farmer.
He used to have no idea of the third.
"The man with the scar through his eye is instantly familiar to Warriors.
There is no doubt in his mind that he is the same as the child he once called ‘Little Brother.’"
A look at Warriors' and Time's relationship across two separate time frames.
They could hardly hear each other’s voices over the roaring rain and thunder, but it seemed they shared a single-minded goal of getting the hell out of the weather they’d found themselves trapped in. The bright lightning illuminated their bodies every few moments, followed by closer and closer claps of thunder.
Until…
Well, maybe it wasn't such a good idea to travel in the middle of a thunderstorm.
AKA The One Where Two Dissimilar Links Swap Bodies And Try To Hide It From The Others
The younger heroes of the chain have been split from the others during a portal shift and now find themselves in an unfamiliar forest. No doubt, it's the Lost Woods, but nobody knows who's era it is or why they ended up here. Not only that, but there's a hero they've never seen before: a Link with a fairy companion and the Master Sword on his back. Something about him is familiar, but he acts strange. With none of the adults around, he's their only guidance. But there's a darkness in the forest, and this new Link is oddly tight-lipped about it. What secrets is this hero hiding, and what needs to be done before they can reunite with the others?
“We're looking for the Hero of Time,” the kid says. The words have a funny intonation, like it's a title he's used to talking about in a different, more formal context.
Link stops walking.
“The Hero of Time is dead,” he says evenly.
Time has never liked haircuts.
Twilight blinked, clinging tenaciously to consciousness, and was disturbed by the way color seemed to leech from his surroundings—swathes of greens, blues, and twilit golds spilling away like sand through an hourglass. He blinked, imagining he could still feel the metallic slide of the Iron Knuckle’s battle axe, the buttery-smooth way with which it parted his skin. He blinked… and was overtaken by a gray shroud.
Fog thickened the air, a wispy, humid cascade that swelled from the ground like sweat from a waking beast. Twilight startled upright and drew his sword, gritting his teeth in anticipation of pain, but none came. After waiting several tense seconds to make sure he wasn’t about to be attacked, he glanced down and saw that his tunic was intact. Slipping his waist guard aside and lifting his undershirt revealed healthy skin.
Yet the words drifted by once more—an echo dissipating as it stretched. His wound isn’t healing.
"How many times is this?" Wild asks, giving him a small smile as a greeting.
Time sighs. "The last one."
"And how many times have you said that to me?"
It’s said matter-of-factly, not overconfidently, and Time hates that Wild knows that it’s not his first, second or even third reset.
And to think all Time's current problems would be solved if Wild just got out of his way.
A.K.A. Unstoppable force meets immovable object.
Or the Sans boss fight but the only stake is Time's sanity. And maybe his life. But mostly his sanity.
Time is no stranger to moving through the course of his namesake. He has meddled with the flow of time often enough that he should have expected something like this to happen at some point. Still, when he finds himself face-to-face with a much younger, much less scarred version of the champion, he is taken a little by surprise.
Monsters’ bodies are slow to fade into smoke, sometimes. Especially when there are so many in such a small area. But the littering of monster corpses across the battlefield does not disguise the sheer amount of Hylian bodies. Nor does it distract from the oppressive presence of the figure standing in the middle of it.
It stands over seven feet tall. Its armour shines under an invisible sun, gleaming brighter than should be possible – like it's not quite on this plane of existence. The large helix sword is idly resting in one hand; it weighs nothing in the warrior’s grip. Even with its back turned to him, Link feels as though its eyes are on him, weighing down upon his shoulders, a condemnation. A judgement.
And then it turns to meet his gaze, and that sick mockery of his kid’s face is staring back at him.
