The Search for Loki by UnderwaterArch
Fandoms: Loki (TV 2021), Marvel Cinematic Universe
03 Oct 2025

Summary
Loki was gone—at least, the part of him that Sylvie knew.
Upon travelling to New Asgard to find his brother, Sylvie buries a lock of his hair as a way to say goodbye. But soon after, she finds a small tree has grown in its place. With the help of her new friends, she investigates the mystery of the tree—and its connection to Loki.
The feel of cool damp grass on her hand. The smell of ozone on the breeze. The dew seeping into her pant legs. Everything felt in focus and so very real, not at all like a dream.
And Loki was still there.
He’d spoken, he’d looked at her, and then he’d laid his head back down and closed his eyes. Completely still, except the rise and fall of his steady breathing.
Alive.
It would be easy for her to remain transfixed on this subtle motion, the endless pattern of inhale/exhale. She shook off the temptation and looked him over; he was covered in a thick shiny substance. Transparent for the most part. Tentatively, she tried to wake him.

Summary
Loki helps the new TVA build a society for all the variants with no place to go, like him.
Sylvie and his other self found each other and are living the life he desperately wanted. Unwilling to risk making a version of Sylvie that won’t be ok, he tries to move on with his life, but a Loki variant who looks exactly like her is making things complicated.Loki tries his best to separate the two of them in his mind while helping the variant heal from eons of TVA experimentation, and his own heart in the process.
He didn’t flinch away from the touch, but didn’t respond to it either, “Did you just come here to flirt, or is there something else you wanted?”
His counterpart sighed in resignation, “No, I do have something to tell you,” he dropped his eyes to the floor, then looked up and grinned widely, “but you’ll have to catch me first.”
With that, he disappeared in a flash, hoping to tempt Loki into a magical game of cat and mouse.

Thor fell onto the beach one day by UnderwaterArch

Summary
Thor falls into another universe and is forced to kill another version of himself. Then he hears a song from the water, that he simply cannot resist.
It was then (as he made a mental note never to use a narwhal horn as a decorative item) that he heard the song.
A hauntingly beautiful song; so sweet he felt he could open his mouth and have the melody melt on his tongue like spun sugar.
Surely it could only have come from the most talented singer in Valhalla, it so enchanted him.
It drew him towards the water, to the end of a long wooden dock. There, he found the source of the music and stopped short.
The singer rested his elbows on the end of the dock. The rest of his body dangling into the water and he had obviously just been swimming as his long black hair was dripping wet.
When the man saw him, he stopped singing, “You killed my brother,” he said.
“I-uh,” Thor stammered, “I’m sorry. It was an accident. I fell on this hut you see, and he attacked me-“
The man halted Thor’s apology with a wave of his hand. “No need to explain,” he said, “You’ve done me a great service. My name is Loki and I greet you warmly.”

Summary
Sylvie is curious about Loki's Jotun form, but when Loki finally gives in and lets the blue come to the surface he finds there's a bit more of him than he'd expected.
Contrary to what he had emphatically (but not very convincingly) told her, he did in fact have a lot of issues with removing the glamour that kept the Jotun blue hidden below his skin. But maybe this was the right time to change that?
Looking carefully into the bathroom mirror one morning, hair still wet from his shower and wearing only a towel draped around his waist, he let his magic flow over him. First the crimson emerged in both eyes, then the blue spread over his skin like a tidal wave, marked with a pattern of ridges.
A Frost Giant.
He stared at himself for a while, letting his new appearance watch him from the other side of the mirror.
It wasn’t really so bad.

Summary
He’s over it, he’s done. And this time she’s focused on his clothes? Who cares what he’s wearing, all reality is at stake!
“Fine! You know what? You don’t like it?” He fights with the TVA logoed belt buckle at his waist, swipes the belt off with a firm yank and throws it down to the ground with force, “It’s gone! No more TVA logo.”

Summary
While Sylvie looks for a way to prevent the multi-versal war and get Loki out of the tree, his consciousness hovers around her, watching her constantly. That, along with a version of himself he tempted in from the void to keep him company, is keeping him sane while he continues his eternal work. At least it did, until he and Sylvie had a bit of a fight.
I don’t expect what I see when I open them again. The King himself; Loki enters the room, billowing out of one of the doorways, green robes flowing around him, face set in a stern glare. Back straight, chin lifted, horns reaching for the sky, he walks as if he had ten armies at his back.
Barely glancing at us, his cape brushes us as he passes by.
No doubt he expects us to follow him.
I chuckle to myself at his majestic performance. This is almost too perfect. My game is certainly doing… something. I can’t say I know what exactly.
Loki stops when he gets to one of the doorways, turns back and tries to burn us down with his glare.

Summary
His eyes were blown wide at the sight – another Asgardian, just like him. She had the most gorgeous green scales he had ever seen and wore a horned crown (similar to his own but smaller and with one horn missing). It complimented her lovely reptilian eyes perfectly.
He was shocked! He was stunned! He just had to impress her.
Or at least convince her to get out of his kiddie pool.

Summary
The Sceptre is a gift, a wonder, but comes with more than a few burdens.
It opens the minds of these unfortunate creatures to the glorious future he’s planned for them. The truth that flows into each and every one of them from the sceptre’s honed point fills them with a joy they could never have reached without it.
Without him.
They love him.
It’s bothersome.

Summary
Up to this point, he'd been in a fairly consistent (if uneventful) routine; he'd peek at the timelines, make sure Sylvie was ok, see what Mobius was up to, check in on his brother. All from a distance that wouldn’t make him feel too sad to be left out of it all - then he’d fall asleep again and hope his dreams would be pleasant ones.
This time he sat awake with his thoughts.
Just having someone — anyone — come to see him, even a formerly evil cartoon clock he hadn’t been overly fond of, was such a relief he had to strain to prevent himself from sobbing uncontrollably.
It probably wasn’t a good idea to indulge his loneliness when he had such an important job to do, but he found himself counting the non-existent hours, hoping she would come back.

Summary
A Loki pruned to the void during his stay in Asgard’s prison, wanders into the lonely tree lair of Loki the God King and is trapped there.
***
When I’m asleep I’m not tempted to do what I know I shouldn’t.
At first, I thought I would spend eternity seeing only the light of my own magic in the branches — surrounding me like a cocoon — but I can see them now (my friends), I can see the whole of reality.
I try not to see her.

***
He ran his hand down his face. “Ok, fine. You know how before I went to Earth I was working for Thanos? And some people here were working for Thanos, and some of them — one of them — may have uh… not been overly fond of me.”
“Fond?”
Loki took a deep breath and began a gesture laden explanation while intently looking everywhere but Sylvie’s eyes.
