It was so quiet around Mobius.

Big the Cat was fishing with his frog named Froggy, not able to catch any fish. It was so quiet that he could hear his hook land in the pond so clearly. The Crickets were even making a chirping sound that soothed him almost to sleep. When he almost fell asleep, Froggy woke him up with a slap to the face with his tongue. He kept fishing, but something soon caught his eye.

Something or someone ran by so fast that it felt like a sudden breeze picked up out of no where. A blue blur ran by, and he knew right away who it was.

It was Sonic the Hedgehog.

He ran past the pond and through the forest, trying to make his way through. He jumped and ran over fallen trees and tried to get somewhere as fast as he could. His teeth gritted in anger, knowing full well that someone needed his help. He had get there before a certain guy with a mustache did something that he might regret. Sonic picked up the pace, getting there much quicker than expected.

Soon enough, Sonic was running through a base that was made of metal and steel. Once he feet ran alongside the metal, robots were soon deployed out to go after him. Red lights and alerted sounds went off all around him, knowing full well that this guy knew he was here. He kept going, not looking back this time around. He spin dashed his way through a robot as another came after him. He avoided his attacks, but soon spin dashed right through it.

He kept running further into the base as robots kept trying to stop him. Sonic could do this all day, but he had to get there soon. Someone was in trouble, and he couldn't let Dr. Robotnik get away from him this time. Sonic had been fighting him for so long now, but he now had someone captured that he cared about. He had done this before, but something else was going on and Sonic didn't like it.

Dr. Robotnik somehow got the chaos emeralds.

Sonic didn't how he got them so quickly, usually they were on top of these things. He had grabbed the last one before they could even take it. That's how Cream the Rabbit got captured along with her Chao friend, Cheese. She was stuck with him, and he had to get her and the chaos emeralds back. Sonic knew that Knuckles wouldn't let this one go if he couldn't get them back.

Another robot came at him, and Sonic got so angry that it didn't stand a chance. Sonic kept running, but was so focused on getting to Dr. Robotnik that he didn't notice a trap set for him. He was suddenly launched into the air, causing him to lose his balance. He tried to spin dash back there, but then some of the robots were trying to stop him from getting closer.

Then right when he needed help the most, he heard a familiar sound coming towards him.

"Sonic! I've got you!"

In the corner of his eye, Miles Prower in his X Tornado came flying towards him to help him out. He shot out some lasers to destroy the robots, and Sonic soon landed on the X Tornado's wings. Sonic quickly recovered and soon noticed that Amy Rose was there as well to help them. Then he turned to his friend and gave him a thumbs up.

"Thanks Tails, I owe you one," Sonic said to him.

"Don't worry about it. Just go save Cream," Tails said back, "Amy. Give him a ring."

Amy didn't hesitate and gave him one immediately. She looked worried for her friend, and Sonic knew that all she cared about in that moment was getting Cream back.

"Don't worry about Cream, Amy," Sonic told her, "I'll get her back. I promise."

Amy tried to smile, but let Sonic do his thing. He gripped on the ring, feeling that power amplify his power tenfold. The electric power ran all over his body, ready to face Dr. Robotnik. Sonic's power soon charged up, causing him to go into his spin dash. He quickly launched after Dr. Robotnik's base so fast that he flew past all of the robots and straight into the hallways of the base.

Sonic shook his head as got ready to run around, looking for Cream and Cheese. Before he could even do that, someone suddenly came bursting into the base with him. Something about the wreckage made him realize who he was tagging along with. A red echidna showed up, looking pretty upset about what was going on.

Sonic really didn't have time dealing with him right now.

"Knuckles, I know what're going to say," Sonic told him, "But can we talk about this later? I've gotta get Cream and Cheese out of here first. You can even grab the chaos emeralds if you want to."

Knuckles didn't say anything and just crossed his arms in frustration. Sonic rolled his eyes, not having time for this.

"Fine. Let's just get this over with," Knuckles told him, "But you owe me an explanation."

Sonic shook it off for now and went after Dr. Robotnik. He kept running, and Knuckles as usual was able to somewhat keep up with him. He wasn't as fast, but could at least be ready just in case anyone came up from behind them. He looked around and found the lab immediately. Without even hesitating, Sonic spin dashed right into the lab.

Sonic stood there, ready to take on Dr. Robotnik as he stood amongst his robots and lab equipment.

Dr. Robotnik was shocked to find the hedgehog standing there with no scraps or bruises. Sonic gritted his teeth in anger, finding Cream and Cheese trapped in a container. She looked scared as she held onto Cheese close to her.

"Sonic! Don't just charge in like that!" Knuckles cried out after him.

"Sorry Knuckles, but I don't have time for this right now," Sonic told him.

"Sonic and Knuckles... You two are working together? This is a rare thing, isn't it?" Dr. Robotnik said to them, "Knuckles, you don't seem like the team type. I always thought you were better off by yourself and not with these group of misfits."

Knuckles easily got upset by this, but Sonic tried to step up so he wouldn't cause trouble.

They both looked at Dr. Robotnik as he stood up, ready to use the chaos emeralds. They were all in separate slots, but also behind a protective barrier so that no one could take them. Whatever he was planning on doing with them, Sonic knew that it wasn't anything good. All he wanted was to get Cream and Cheese out of there. With Knuckles here, he could easily get them away as he got the chaos emeralds.

Cream and Cheese looked happy to see Sonic and Knuckles together.

"Don't worry Cream, Cheese. We'll get you out of there," Sonic told them.

"No way you're getting in my way this time Sonic!" Dr. Robotnik growled out.

Sonic soon noticed Dr. Robotnik pull out a switch that was connected to the chaos emeralds's power. He gritted his teeth, knowing that he wasn't playing around this time. Dr. Robotnik seemed to notice his frustration as he got close to pressing it.

"Don't even think about taking the chaos emeralds or your little friends here," Dr. Robotnik told him, "You don't know what'll happen if I press this button. It could activate the chaos emeralds's powers or maybe even robotize your little friends here."

Sonic hesitated to go after the button, even though he knew that he could easily grab it. He couldn't risk it if it might hurt his friends however. Knuckles seemed to understand and didn't move as well. He gave Sonic a look as if he was looking for a plan of some sort. Before Sonic could even come up with anything, a couple of robots charged their way over here from outside of the base.

They went after Sonic and Knuckles, causing them to dodge and avoid their attacks. Dr. Robotnik waved his arms around, trying to get his robots's attentions.

"Stop! Hold your fire!" Dr. Robotnik cried out, "You idiot robots! You're destroying my work!"

Sonic then noticed the robots getting close to shooting at Dr. Robotnik's equipment. It was getting destroyed in the process, which only made Dr. Robotnik even more upset. He smiled, knowing full well how to get Cream and Cheese out of here. He immediately went after the robots to get their attention.

"Hey you! I'm right here!" Sonic called out, "Come and catch me!"

Sonic then launched towards Dr. Robotnik, causing the robot to shoot at him.

"Ah ah! N-No! What do you think you're doing?!" Dr. Robotnik cried out, "Stop!"

The doctor ducked, not expecting the robot to shoot. The bullets shot past him and soon hit the barrier with the chaos emeralds. Dr. Robotnik then soon realized that he pressed the button by accident. Knuckles's eyes widened in shock, knowing full well that they had to get out of there quickly.

"Sonic! What did you do?!" Knuckles cried out.

Sonic tried to get Cream and Cheese out of there, but he looked back at the chaos emeralds. Something was happening as the electric shocks were coming out of the barrier. It was getting stronger, and the chaos energy made his quills feel a bit off from the energy. His power felt even a bit off from the impact of the chaos emeralds's power getting stronger.

He tried to get Cream and Cheese out of there, but the container wasn't budging.

"Knuckles! Get Cream and Cheese out of here!" Sonic cried out, "I'll get the chaos emeralds!"

"What?!" Knuckles cried out, "But you said that I could take them myself!"

"Knuckles! Now is not the time for arguing!" Sonic cried back, "Just do it!"

Knuckles noticed him struggling to open the container and agreed to help. Sonic immediately went for the chaos emeralds, but felt that energy hit him like a ton of bricks. The eletric current shot all around him as he tried to grab one of the emeralds. Dr. Robotnik noticed him do this and tried to stop him from doing so. Dr. Robotnik couldn't even handle the electric current, and it burnt his glove from intial shock.

Sonic held onto it as his powers glitched from golden to blue. Blue sparks came flying off of his body, feeling that power charge him up. It even felt like something was wrong as he tried to take the chaos emeralds out of the slots. He suddenly felt like something was coming as he tried to take the chaos emeralds.

Before he could, he suddenly felt a strong power come over him. He thought he heard someone call out his name, but it felt like it was out of reach. Then everything went white as it grew more and more.

"Sonic!"

That power grew, and for a moment he could see all of the chaos emeralds as if they were showing him something important. Images of people that he didn't know came up. All of them were in school uniforms that he'd never seen before. He had never met anyone like them before, but someone stood out that somehow connected to the chaos emeralds's energy.

Someone with green hair and freckles. He didn't look that strong, but Sonic felt something about him that reminded him of the chaos emeralds's energy. He didn't why or how, but the power of the chaos emeralds's powers were soon dying out. All he could think about who they were and what this meant.

Then soon enough that power faded away as he blacked out.

Finally!

Here's a Crossover story between Sonic the Hedgehog and My Hero Academia! I've been really enjoying Sonic for a long time now, so I thought that I might write a story about him and another series that I enjoy! I love what is going on with Sonic and the franchise lately. With Sonic movie 4 being worked on, I know that the franchise is only going to get better from here. I can't wait to see what you guys think of this! It's just interesting to see what comes of this story, so here it is!

This is kind of somewhat based off of Sonic X, but still doing my own thing. It's more based off of the situation that they're in if anything. Also, there will references to the movies, but I'm still doing my own thing. It has nothing to do with what he's going through in the movies, but more like taking things from it and making it my own. My Hero Academia will be set sometime after Bakugo finds out about One for All.

Enjoy!
