💙🧪Intoxicated💀💙 (Sonic au)

Introduction: The gas

Third Person

Eggman had retired.

He had announced his retirement and assimilation to the good side to the whole of the resistance.
He explained his reasoning was he felt almost more satisfied when he was Mr. Tinker and he simply wanted to raise Sage, Metal, and Belle.

Everyone was happy by his side change and everything started to calm down.
The resistance happily accepted Eggman's peace treaty, and the two got along well, and Shadow was just as content.
The two became close, like father and son.

However one certain hero missed the adventure and having a little fight every day with his arch nemesis.
Sonic got bored and would run around, looking for someone to stop and keep people safe from crime.
The cases at GUN had slowed down as well and team Dark found themselves with even more time to themselves.
Rouge spent time with Knuckles, and proposed to him so the two fiancées had time to plan their wedding.
Shadow spent more time with Cream and Vanilla and Eggman, adjusting to living a more relaxed life.
Omega and Metal started hanging out as robots and did, idk robot stuff...
Surge and Kit, who had joined a couple years back, started their own life. Surge started working with Amy in helping the town with projects and charity donations. Kit moved in with Tails, wanting to work on projects with him. The two became close friends and joked calling themselves "platonic boyfriends" since both of them were Aro ace.
Eclipse had also joined since the Black Arms abandoned him on earth, and he worked on fixing his relationship with Shadow at Amy's request.

Now everyone was happy. Everyone was satisfied with the time they had now.

Except Sonic.
He knew it was rough being hero but he missed the adventure and action. He craved being able to feel that rush of adrenaline instead of the crippling loneliness of not being needed anymore.

And that rush returned.
At a price.

It was a mid-temperature day in August, and Sonic and Tails stepped into the old abandoned lab.
The ceiling had fallen in and it was dark but they could recognize the old familiarity of Eggman's furnishing choices.

"Welp! Here we are buddy!" Chuckled Sonic, his necklace jingling slightly as they jumped down from a broken step.

"Yep, now remember Sonic, we're just here to find old badnik parts, and possibly any experiments that Eggman left behind that could possibly harm any animals." Said Tails, holding out his monitor towards the room. "Then we head back as soon as possible because I have a project to work on with Kit and Amy asked you to come join her with helping Knuckles and Rouge plan their wedding."

"Yeah, yeah, got it. Man how much planning does one wedding take?" Sonic groaned as they walked through the lab.

"Makes sense why you don't know since you don't have a partner." Said Tails.

"Hey! I did!" Said Sonic.

"You and Amy broke up three years ago. That doesn't count." Said Tails, with a smirk. "And I know you have a crush on someone. You just won't tell me who."

"Pfft, whatever!" Said Sonic, rolling his eyes.

They continued walking and Sonic stopped ahead of Tails.
"Hold on." Sonic said, placing his ear to a wall.

"What is it?" Asked Tails.

Sonic listened closely. He could hear a faint hissing down behind the wall, like a tank had been punctured and was letting out air.

"There's something behind the wall... Tails scan it real quick." Said Sonic.

Tails held his scanner up to the wall and gasped.
"Oh yeah! There's a secret door here! Hold on the button should be rightttt....there!"

He had run his hand along the wall and pressed it against a certain spot.

The wall slid open to reveal a vault like room. Some of it had collapsed, but most of it was intact. And there were a bunch of air tanks in it, like the kind one would store helium air in for pumping balloons. One had been punctured in the side, and some greenish gas was slowly leaving it.

"What's this?" Asked Sonic, getting closer to it.

"Sonic, I would suggest not touching it, we don't know if it's poisonous or not." Said Tails.

"Tails, buddy it's fine-"

Then the thing popped and gas sprayed everywhere near Sonic.
Sonic yelped and coughed.
"AUGH! What the hell?!?" He said, trying to fan it away and squeezing his eyes shut.

"Sonic!" Yelped Tails, running towards him.

But then something hard hit Tails in the back of his head.
Everything went black and he collapsed onto the floor in a heap.

-------------

Amy tapped her foot against the tiled floor of the cafe.
Knuckles and Rouge were sitting across from her, flipping through a binder of photo ideas for their wedding.

Sonic was extremely late.

"Come on where is he?" Groaned Amy.

"Come on Ames, hon. You know he hates sitting still, he's probably lost track of time and is off exploring the woods or taking a nap." Said Rouge. "Besides, I don't think he'd be as much help with planning the wedding."

"I know but he should be here! He's the best man!" Hissed Amy, poking her fork at her croissant.

"Eh, I don't care if he's here or not. He just better not do anything stupid at the ceremony." Said Knuckles.

Then the door flew open and the three looked over, expecting to see the blue blur.
But instead it was Tails, with Kit right next to him. The twin-tailed fox looked distraught and lost, his fur was messy and he had dirt on his shirt and red scarf. He had slight tears, glazing over his eyes.

"AMY! KNUCKLES! SONIC IS MISSING!" He cried, running over to them.

"What?!?" Gasped Amy, standing up.

"What happened?!?" Barked Knuckles.

"I-I dunno, he-he, we were exploring one of Eggman's old labs and-and there was this gas and I was knocked out and, and, and, he- This!"

Tails then held up the object that set all three of them into extreme concern mode. Sonic's favorite necklaces.
A dog tag and a necklace with a small gold ring as the pendant.
Sonic never went anywhere without them.

"Amy! Call everyone in the resistance I'll call GUN and have everyone on high alert!" Said Rouge, getting up from her seat.

"Got it, every recruit and member will be looking for him!" Said Amy, also following Rouge.

"Don't worry, Tails, we'll find him." Said Kitsunami softly, rubbing their hand on the fox's back to calm him down.

Tails just sobbed into his friend's chest.

The search for Sonic started.

They searched all day.
No Sonic.

A week passed.

Two weeks.

Three weeks.

A month.

A year.

Sonic wasn't found.
One detail Tails forgot to mention though.
The tanks went missing as well.
