STH Rarepair Week Day 1: First Kiss / First Encounter

You can check it out on ao3 here if you prefer.

Summary: Knuckles finally learns the odd truth behind Sonic's weird behaviors after all these years. He didn't expect it to be a whole other person, and neither of them expected they'd fall for each other. They've made it work though, even if it can be rough sometimes.

Pairing: Knuckles/Fleetway Super Sonic

Warnings: A tiiiiiny smidge of violence in one part? Not really much but warning just in case.

Word Count: ~2800 words

AN: Just so people who are familiar with my stuff are aware, this is unrelated to my Chaos Uncontrolled AU. It's actually related to a fic I never finished, got 8k words deep in it too, but I felt the urge to do something for it.

Knuckles had known Sonic for a long time. He’d been dragged into the hedgehog’s small circle of friends, consisting of just Tails at the time so he thought, pretty much immediately in the wake of everything that happened on Angel Island. Part of him thought that Sonic wouldn’t forgive him for being tricked by Eggman, but that hadn’t been the case. Once the Death Egg had been dealt with Sonic and Tails had come back to make sure he was ok, and also to ask if it would be ok if they visited every once in a while. It didn’t take long for him to say yes, not that he made it look like he was desperate for company or anything. Sonic and Tails were just… decent company is all. Plus he still felt bad for going against them.

As time passed the duo would visit him when they could, even drag him into adventures from time to time. Those adventures got more frequent the longer they knew each other. It was on those adventures that he started to realize there was something Sonic wasn’t telling him about.

It started off easy enough to ignore, especially when he was being distracted by whatever was going on. Though the more time he spent around Sonic the harder it was to ignore. The hedgehog would seemingly… talk to himself sometimes. Even odder was that when he did it with Tails nearby the fox didn’t seem to even care. Knuckles really wanted to ask what that was all about but any time he tried Sonic found some way to change the topic. Frankly it was getting frustrating.

It would be some time, and many failed attempts, before he managed to figure out what was going on. For all his attempted plans though, he would end up finding out completely by accident. Sonic and Tails were on Angel Island for the day, making sure Knuckles wasn't lonely even if he assured them he was fine. Sonic had gone off to run around for a bit and Tails had been tinkering with something nearby as Knuckles watched the Master Emerald. 

"I've been trying to work on some stuff that would help keep the Master Emerald safe while you were away." Tails paused in his work to glance over at Knuckles. "If you'd actually consider using it anyway…" The fox looked slightly nervous.

Knuckles hummed. It would be nice to have some more peace of mind when he couldn't watch it. "Would it be… easy to use?" He asked. Technology for the most part eluded him. Most of the time when Tails tried to explain something he was working on he couldn't keep up at all.

"Yeah!" Tails perked up. "I made it my top priority to make it easy to use. I've even had Sonic and Fleet test it out to make sure."

Knuckles blinked. "Fleet?" His brow furrowed in confusion. That wasn't a name he'd ever heard before.

Instead of possibly just explaining that it was some new friend they'd met, Tails froze. "Oh uh… I must have misspoke. Heh heh." He looked away and rubbed the back of his head.

Now this was odd behavior. Plus Tails was an awful liar. "What did you mean to say then?" Knuckles tilted his head. He'd give the fox the benefit of the doubt for now.

"I… uh…" Tails' eyes darted around. "Froggy..?" He winced.

Knuckles huffed. "Nice try. Wanna give me the truth?" He crossed his arms.

Tails' ears drooped. "I do…"

"But?" Knuckles pressed. This honestly didn't seem like too much of a deal to him. Why was Tails so hesitant to tell him?

"I'm not sure I should…" Tails sighed.

Before Knuckles could say anything else another voice cut it. "Don't worry about it kid. I can explain myself." There was suddenly a golden hedgehog there. One that looked remarkably like Sonic in his super form. As he walked over he ruffled the fur on Tails' head, an action that looked almost automatic. "Good to properly meet you Knux. I was wondering when this was gonna slip." Despite the hedgehog's casual demeanor Knuckles could tell he was nervous.

"... you're Fleet then?" Knuckles cautiously approached. It was hard to ignore the sheer amount of chaos energy he could feel coming off the hedgehog.

"The one and only." Fleet eyed him, shuffling his feet. "I assume you have questions."

"Several." Knuckles nodded. "First, who are you and why have I never seen you before?"

Fleet seemed to hesitate before sighing. "Well… if we're just gonna rip the bandaid off here. I'm a being made up of chaos energy who's been with Sonic his whole life. Like I came into existence when he was born. Something to do with the emeralds taking a shine to him." He waved a hand. "We're not too sure." He crossed his arms. "Reason you've never seen me before is cause typically only Sonic can, but I can 'pilot' for a bit I guess. That let's me interact with the world and be seen." He shrugged.

"So you're just… sentient chaos energy?" Knuckles didn't quite relax at the explanation, but at least Fleet seemed to be telling the truth. It would be a rather unbelievable lie if it was one. Plus it would explain the chaos energy he could feel.

"I guess?" Fleet hummed. "Kinda a simple way to put it though." He mumbled.

This had certainly not been what Knuckles had guessed was going on, but it did put some things into perspective for him. Especially Sonic seemingly talking to himself. He glanced at Tails. "How long have you known about him?" He gestured to Fleet.

Tails looked away. "Uuuuh since before we met you. I accidentally met him at the end of the first adventure me and Sonic had."

"I'd gotten all the emeralds." Fleet hoped in. "Turns out if I'm not careful that much chaos energy can cause me to go a bit… wild." He looked at the floor. "Didn't know that at the time though. Tails ended up seeing me before me and Sonic could figure it out." He cracked a small smile and looked over at Tails. "It worked out though." The fox smiled back. Knuckles opened his mouth to ask something else but Fleet rose a hand. "Sonic didn't want to say anything because people haven't exactly taken kindly to my existence in the past." He frowned deeply.

"If it makes you feel better." Tails jumped in. "Only me and Shadow know, and Shadow only knows because he could tell that Fleet was there. Sort of."

Knuckles hummed as he watched Fleet. It was clear the hedgehog was still nervous. “Alright. Fine.” He sighed and held out his hands. “At least I know now.”

Fleet blinked. Knuckles crossed his arms. “That’s it?” Fleet looked dumbfounded.

“Were you expecting something else?” Knuckles tilted his head.

“Well… I mean…” Fleet seemed to be struggling to get his words straight. “It was just a whole thing with Shadow and… I don’t know, it's almost always been a big deal…” Suddenly his head whipped to the right to glare at empty space. “Stop laughing! You’d be acting the same way in my position!” Based on his eyes narrowing further Knuckles was willing to bet the laughing had only gotten harder. Fleet turned back to Knuckles, his arms now crossed and ears flat against his head.

“Well so long as you don’t pose a threat to the Master Emerald I’m fine to trust you for now.” Knuckles nodded, and Fleet perked up a little bit.

“I see.” Fleet cleared his throat. “Well uh. Good I guess. Yeah…” He tapped his claws together nervously. “Good… talk.” With that he was gone and Sonic was there on the ground, still laughing.

Fleet collapsed wordlessly against Knuckles. The echidna didn’t even flinch. “What happened?” Knuckles eventually asked once Fleet had settled himself. Fleet didn’t really have the emotional energy to even try and describe the day he’d just had. All he knew is he wanted to calm down and hang out with his partner. Not that he even knew how he’d managed that. Ever since he’d revealed himself to Knuckles the two had gotten closer, and things had just… evolved from there. It helped that him and Sonic were able to be separate finally. That had been a pain while they’d tested different things. He’d had far too many close calls than he was comfortable with… both for himself and others.

Knuckles hummed and put an arm around Fleet. It was nice, not needing to articulate his feelings just yet, but still getting the comfort he’d been seeking out. The two stayed there for a while, Fleet wasn’t really trying to keep track of the time. Which was still odd to him. Before sitting still this long would have been torture, but now he was content to just stay at Knuckles’ side.

“Something with the emeralds?” Knuckles spoke up again, keeping his gaze aimed forward. 

With a sigh Fleet extracted himself from the comfortable position and balanced his head on his hands. “Yeah.” He pinned his ears down. It was still fresh and he didn’t really want to talk about it, but keeping it to himself might only make things worse. “Tails was messing with one, I wasn’t really paying attention to what he was doing. Then out of nowhere… boom!” He waved a hand aggressively. “I couldn’t think straight. Made a mess of Tails’ lab and… and…” He sucked in a sharp breath. “And hurt people.”

There was a moment of silence and then a hand on his shoulder, he tried to shy away from the touch but it was firm. “I get why you came here then.” Knuckles didn’t look sympathetic, but Fleet much preferred that. He didn’t want to be pitied. “You know that if something goes wrong here, I could probably use the Master Emerald to help.”

“S’part of it I guess.” Fleet admitted. Of course that was a pretty natural conclusion to make. “I think just being around you helps too.” He added, much quieter. Knuckles just slowly pulled him closer, giving him plenty of time to pull away if he wanted. Fleet didn’t fight him. Hopefully some quiet time spent here would help clear his mind.

“Where is he!?” Knuckles shouted as he approached an injured looking Sonic.

The blue hedgehog grimaced as he pushed himself to his feet. “He’s up ahead. Shadow is keeping him busy for now.” He went to rub the back of his head but winced. “Not sure how long he’ll last though… Fleet was exposed to a lot of chaos energy…”

Knuckles grit his teeth. As much as he wanted to rush in there right now and help Fleet he needed more information. “What happened?”

“Was fighting Eggman, I used the emeralds. Fleet was there too but I thought it would be fine. He was trying to stay out of the fight.” There was clear regret on Sonic’s face. “Somehow he managed to pick up on it. He’s been extra sensitive to it lately.” He shook his head. “We have no idea why.”

Well that wasn’t a lot to work with, but Knuckles would have to make due. “I’ll see what I can do.” He grunted, just seeing the grateful look that Sonic gave him as he ran off. True to Sonic’s word Fleet was just ahead. The golden hedgehog had a hand gripped around Shadow’s throat and a crazed look in his eyes. Around them were the ruins of what must have been one of Eggman’s bases. Knuckles would be willing to bet destroying the structure had at least distracted Fleet long enough for him to get here. Thankfully he'd already been off of Angel Island when he’d been contacted. “Hey!” He shouted and one of Fleet’s ears swung towards him. “Put him down.” Knuckles growled.

Fleet turned to look at him. An excited smile crept across his face, one that was still disturbing. “Knuckles.” He sounded genuinely happy to see him, but yet he still held Shadow aloft. “So nice to see you here.” He closed his eyes briefly as he exposed his teeth with his smile.

It was definitely disturbing to see such pleasant expressions aimed at him while Fleet still gripped tightly at Shadow’s throat. Said black hedgehog was still struggling. “Put. Him. Down.” Knuckles narrowed his eyes, keeping his tone firm.

Fleet’s pleasant expression faded as he frowned, ears drooping. “Awe, but I was having fun. A few more minutes can’t hurt right?”

“Now, Fleet.” Knuckles took a step forward. He knew he didn’t stand much of a chance in a fight, but he also knew he was one of the people least likely to be attacked. Of course that list consisted of Sonic and Tails too, but he tried to ignore how injured Sonic had looked when he saw him.

The golden hedgehog pouted but did drop Shadow. The other hedgehog fell to the ground gasping for air. Knuckles cautiously approached as Fleet floated down to the ground. Fleet’s grin still looked feral, but at least he didn’t seem inclined to attack Knuckles. For now. Though of course Knuckles didn’t come unprepared. As much as it would be nice if his presence alone could calm Fleet down he knew that wouldn’t work. Tails had sounded rather frantic in his distress call after all.

Before Fleet could move away Knuckles threw his arms around him. Something in between a hug and a grapple. Thankfully Fleet went rigid as he no doubt tried to figure out what was going on. In those precious few moments Knuckles called upon the power of the Master Emerald to neutralize the excess chaos energy in Fleet’s body. He could feel when it started to work as the golden hedgehog collapsed more and more heavily against him. If there was another way Knuckles would much prefer to use it, Fleet always looked so tired and out of it after. Though he also knew that Fleet would much prefer that to hurting anyone else.

Finally Fleet slumped against Knuckles completely, his breathing evening out as he fell asleep. Knuckles mentally sighed in relief, though he did wish he was able to get here sooner. A glance over at where Shadow had been revealed the hedgehog had left at some point, probably to tend to whatever injuries he had. No doubt Sonic would check up on his rival later. Speaking of the blue hedgehog, Knuckles watched him carefully approach. He was limping slightly, but was doing his best to hide it. What he didn’t hide was the relief on his face when he spotted Fleet in Knuckles’ arms.

“I assume everything’s good now?” Sonic was still looking at Fleet, some sort of expression Knuckles couldn’t place on his face now.

“For now. You should go rest. I’ll take care of him.” Knuckles adjusted Fleet so he was holding him more comfortably.

Sonic opened his mouth to say something but closed it. Perhaps thinking better of whatever he was about to say. "I'll leave him to you." He shuffled his feet and winced. "Just let me know how he's doing once he wakes up ok?" Knuckles simply nodded before going off to collect the Master Emerald from where he'd left it.

Fleet woke with a start, but didn’t try to move. He was utterly exhausted, a feeling he knew well. Though he wished it wasn’t so familiar. Just as he suspected he spotted the Master Emerald after a moment of visually searching for it, so that also meant…”Good to see you up.” Knuckles was sitting down next to him, close but not touching. “How are you feeling?”

“About how you’d expect…” Fleet curled in on himself, not quite making a proper ball. “I feel like I could sleep for a whole year…”

“I’m sorry.” Knuckles, as he always did after something like this happened, sounded genuinely apologetic.

“I know.” Fleet reached his hand out blindly, Knuckles thankfully took it. “And I keep telling you it’s ok.”

“Doesn’t mean I won’t feel bad about it.” Knuckles huffed. “Even with your permission.”

Fleet felt like he could continue this conversation, but nothing new would be said. They’d had this same back and forth so many times. Honestly Fleet hated to think about how common of a conversation this was becoming. He hated that it was brought on because of his inability to control himself around chaos energy. "Fine." Was all Fleet could manage. He was tired anyway. The two stayed in silence for a while. It was comfortable, like it usually was between them. "Thank you." Fleet's voice was soft even to his own ears.

Knuckles pulled Fleet closer. "I just wish I could stop it from happening."

"You do your best." Fleet squeezed his hand.

There was more silence and Fleet figured it would be safe to slip back into sleep now. What he wasn't expecting though was for Knuckles to press his muzzle to Fleet's head, careful to avoid pricking himself. Fleet's exhaustion riddled mind barely registered it as a kiss. A sort of tentative one, but one all the same. As he drifted off the sleep he couldn't help but realize that was the first time that had ever happened.
