Author's Note: Didn't had a chance to mention two big news in the last chapter. The first I learn that my story is also on TV Tropes if anyone knows about that website. My story is on the My Hero Academia Fanfic of where the Crossover Section is at. Didn't think that would happen but it really is great to see some recommend my story as Quality. Special thanks to aara941 for recommending my story on TV Tropes.

Finally, big news last weekend that a second MHA Film is coming in Winter 2020. Don't know where it will take place. Maybe it'll take place right in between Seasons 3 and 4 like Two Heroes did in between Seasons 2 and 3. Will hear news about it perhaps in the Fall when Season 4 gets underway. Speaking of Two Heroes, I may have plans for that in the future. I'll let you guys know about soon.

Finally, a big milestone achieved. Congrats to Jlyman as he is the 100th Reviewer earlier this week. Okay, now on to the chapter.

Chapter Nineteen: Sonic vs. the Nomu


Back in space, on board the Death Egg, the rest of the Eggman Empire suffered a ton a damage from their fleet of ships by the Blast Cannon. Many of the ships were destroyed. Other ships were in the hangers of the Death Egg being repaired. Thousands of Egg Fleet Fighters were destroyed by not only the cannons but some laser blasters from the Blue Typhoon. It was gonna be a long day for the empire to gain as more of their forces after encountering the Freedom Fighters, trying to get in to Earth.

Inside the bridge, Eggman was not happy. He empire fail him in letting Sonic get past him. Now, there was a problem they had to deal with. With Sonic and the Freedom Fighters on the planet, his chance at invading Earth is now at the point it's not good at one. Plus, he's dealing with another problem of Shigaraki and the League of Villains invading the USJ. They were so busy dealing with Sonic, they totally forgotten about that situation.

"Great! We let that hedgehog and the Freedom Fighters squeak by us and now their on the Planet Earth!" Eggman yelled.

"So that means our invasion plans is in big trouble. This is not good." Scratch said.

"But how did Sonic and the others find out about our plans? We deleted all data from our base right before we left." Snively said.

"Was Coconuts ordered to delete it? Remember, boss you ordered him to delete all of it before we left Mobius?" Orbot asked as Eggman, Snively, and the minions turn to the Monkey Badnik.

Coconuts look around with them staring at him. "W-What? Was I suppose to be one that was deleted?" He asked when a blade shot out near him. He flinch when he saw Stain using the new weapon Eggman gave him.

"I guess you didn't learn to follow orders from your boss." He said, ready to launch another blade at him.

"Okay, okay. I didn't delete it. I thought we didn't have to worry about it because I thought Sonic and his friends would be dumb and stupid to find out we're long gone." Coconuts said as laser came near him.

"Idiot! I should throw you into space for the failure you've created!" Eggman yelled, aiming his laser gun at the Monkey Badnik.

"So what are gonna do now? Our invasion plans have taken a hit. Sonic and the Freedom Fighters are now on Earth. No doubt they'll be going around the planet to try to stop us and blocking our chance at the invasion. Plus, we have to worry about what's happening at our other plan. The one those people at the USJ Building." Snively said.

After hearing it, Eggman slapped himself. "Totally forgot about that situation. We were so busy catching on up Sonic and his friends in space, we forgot about what was happening at USJ. Is our drone still there?" He asked.

"I believe so, sir." Snively said as he activates the screen.

The drone's point of view on screen shows the students in USJ at the Central Plaza. They were surprise of many villains being down on the floor. What was curious, that both All Might, Shigaraki, Kurogiri, the Nomu, and many students were looking on at the Shipyard Zone with shocked faces. Eggman and his minions were curious as they turn the drone camera around to see. They now were shocked to see non other than Sonic the Hedgehog, standing on the rock with Izuku in his arms.

"What's the hedgehog doing there?" Eggman asked.

"I'm not sure but… look what happen to that Midoriya boy." Snively asked as they saw Izuku all with blood, bumps, and bruises from the Nomu he got beat by.

"What happened to him?" Cubot asked.

"Not sure. But he was beaten to a pulp that for sure." Grounder said.

"Then where's the Chaos Emerald?" Eggman asked as the drone see the emerald on the ground, all black. "Looks like the emerald lost power. Wonder how that happened?"

"But why is the hedgehog there? Almost like he just appeared there all suddenly." Snively said.

"I'm not sure. But I won't let that hedgehog or those idiots who attacked the USJ, get their hands on our targets! Is the ship ready? Eggman asked.

"Yes it is. We also got the robot inside as well. Plus we got our weapon in as well. Everything's prepare." Snively said.

"Good. Order everyone to the hangers and prepare for liftoff Time to pay a little visit to our enemies." Eggman said with a smirk.


Back at the Police Force HQ, Tsukauchi and Tamakawa were called in to the Chief of Police Office. Both men enter as they see the chief on the phone from his desk. They heard his tone is very urgent. He ended his conversation by hanging the phone. He look up to see the officers standing in front of his desk.

"Gentlemen, I just got a call from Principal Nezu at U.A. and it's a very serious one. Woof." Kenji Tsuragamae said, who's head is shape of a beagle.

"Let me guess. The media came back." Tsukauchi said.

"Even worst. One of the students of a class came running to the office. He said that the student mention Villains have infiltrated the campus. I guess we learn now of how the barrier got destroyed. It was the Villains that use the media as a decoy to sneak in to the campus. Woof." Kenji said.

"What?! Our squad was just there earlier today!" Tamakawa said.

"Apparently, we should've kept our men there in case anything happens. The teachers are heading over to the USJ Building to rescue the students. Alert everyone to get to U.A. as quick as possible. Woof." the chief said.

"Yes, sir." the two men said before running out the office.

The alarms in the building rang. Officers got the call of the situation at U.A. Many of them put on body armor, arming with pistols, shotguns, and sub machine guns from the weapons room. Other officers, who were SWAT change into black utility uniforms with ballistic vests, helmets, and goggles. They were armed with M4 Carbines. Packing a couple of flash bang grenades, tear gas, and sidearms. Finally, getting equipped with shields to break in to the building. SWAT members got in Lenco BearCat vehicles. Other officers got in their police cars, with red lights and sirens on.

Tsukauchi got his body armor on and pistol ready as he got in his vehicle, following other vehicles out of the garage bellow the building, driving fast to the academy. He's in deep thought about on how the villains sneak in to the academy, using the media as a cover at the same time.

"So this whole thing was coordinated by the Villains all along. They use the media to sneak in to the campus? How the world did that do that if they're that smart?" He thought until memories of his girlfriend, who is a reporter told him about the man, staring at them at the barrier before it was destroyed. "The man she said looking at them at the time before the barrier got destroyed. After it was destroyed, he was gone…. don't tell me… that was him doing the whole thing. Either way, will have answers once we get there."


Back at U.A., Principal Nezu hang up the phone after calling the Police Chief of the situation. He was joined by Iida, along with the other pros inside his office. They have ordered the campus on lockdown yet again but this time with Villains present at the USU Building, this wasn't a drill.

"Are all the students in their classrooms safe?" Nezu asked.

"They are. The lockdown is active." Cementos said.

"Good. The police are on their way. I told the chief to have the police at USJ immediately. For us, we must hurry there and rescue both classes. The good news is that All Might got there first. Iida told me before he came, he saw All Might at the entrance, correct?" Nezu asked as he and the teachers turn to the Engine Quirk user.

"Yes, sir. I told him everything what was happening. He told me to alert you while he hurried there the save both classes." He said.

"What about the teachers? Are they okay?" Midnight asked when Iida look down.

"Only person that's servility injured was Thirteen. I don't know the conditions of both Aizawa and Vlad King. Last I saw them they were fighting the Villains." He said.

"Then we can't waste no time here. We must get a move on to the building at once." Nezu said as they exit from the building, heading towards the dome with Iida leading the way. "Hopefully All Might doing most of the job. He better do it quickly or his limit will expire. Even worst, if his limit is gone, his identity will be revealed to everyone."


Back at USJ, the situation was still the same. It has been a crazy nightmarish day for both Class 1-A and Class 1-B. Students were still in the other zones fighting villains. They were finally getting the upper hand and it was good news for them. The bad news was that their homeroom teachers was heavily injured at the hands of the Nomu. Izuku took on the beast, almost try to win with the help of All Might, who showed up during the fight. However, the Chaos Emerald lost so much power during the entire day. The boy almost faced Death's Door when the Nomu tried to crush his head with it's leg.

Then came a miracle no one from both side saw coming. Sonic the Hedgehog made a surprise appearance, saving the boy from death. The two finallly reunited for the first time in 10 years. However, it wasn't the reunion they thought they would have. Especially at the time of this situation was occurring in the building.

Students, All Might, Shigaraki, and Kurogiri look on at the hedgehog holding Izuku in his arms, while standing on a rock at the Shipwreck Zone. They were stunned by the surprise appearance that nobody saw coming. For the students and All Might, they were thankful he saved the boy. But they were skeptical about him. On the Villains side, Shigaraki was angry after he chance of seeing Izuku die failed. The Nomu roared at the hedgehog.

"Who is that person?" Jirou asked.

"I'm not sure. But he just appeared out of nowhere and saved Midoriya from that monster." Mineta said.

"Whoever he is, it's almost like the lord bless up from the sky to save him." Ibara said.

Momo fall to her knees. Still had tears in her eyes from witnessing the torture from the cinnamon bun at the hands of the humanoid beast. She was relieved he was okay. But the damage was done, seeing the boy being beaten hard. It made her heart broken by it.

"Kurogiri, who is that?" Shigaraki asked in anger.

"I'm not sure. Is he one of the students here?" the mist figure asked.

"Whoever he is, he interrupting my chat with that boy. He's gonna pay dearly for interfering." Shigaraki said, scratching his right neck.

Suddenly, two villains that weren't captured from Mineta's Balls at the time where Izuku and the others attacked to escape, hid in the water behind the rock. They saw Sonic right in front of them. They didn't know who it was. They decided to surprise him by grabbing him in the water to drown him. Bad mistake. Once they try to attack, the hedgehog use his Boost Speed, flying them backwards to the zone. Sonic sped to the Central Plaza within a second. Both Heroes and Villains were stunned of what they just witness as the hedgehog put the breaks in front of the class.

"Izuku!" Momo grabbed the boy from Sonic's Arms, holding him in her arms. She observes the body in horror, seeing it all battered including the broken arm the Nomu broke. More tears came out from her eyes. "Oh, Izuku. What were you thinking?" She hugged him tight. She didn't notice some blood from him was on her left cheek.

Sonic knew he was gonna be okay. He lift his right arm to activate his watch where a hologram screen appeared with Tails on it. "Tails, I'm in the building. And I found Izuku." He said.

"You found him? That's great! I'm hid the Tornado in a wooded area near the building. Knuckles already went ahead so he should be in the building with you. Anyway, how is he doing? Is he surpri-" the fox cub was interrupted.

"He's hurt badly. I broke through the roof from the plane. I just hit a monster like being looking straight at me. It's a war zone right now here. Not sure what went down. Ton of bodies here on the floor. Plus, I'm join by other people that are dressed in these weird costumes. You better hurry up and get in here to see him." Sonic said.

"I'm on my way." Tails said as the hedgehog deactivate the hologram on his watch. He walk towards Momo as she's still holding Izuku's body while crying at the same time. "Hey don't worry. He's gonna be fine. Trust me."

"Fine? You call this fine? Did you see what that monster did to Izuku? That thing almost tried to kill him!" Momo yelled in anger.

Sonic look back at the Nomu as it roar at the hedgehog. He could only smirk at it. He look at both Shigaraki and Kurogiri, who were looking at him especially Shigaraki, who was angry at the hedgehog. "Never seen a monster like that before when I faced other monsters in the past. No wonder Izuku got attacked badly. Those guys must be the ringleaders. A mist like figure and that guy with multiple hands around him. Wonder what happened here before I came?" He thought.

"Sonic!" Everyone look up to see Tails, using his twin tails to fly from the hole Sonic broke through from. Once he landed, he observed the place before turning to Izuku. He ran to his side. "Izuku! What happened to him?"

"Is that a talking fox?" Mineta asked as Tails turn to him.

"Uh, yeah I'm a fox." Tails observe his costume and his height. "Your a small guy. Like the same height as I do."

"Hey, at least I'm a hero!" Mineta yelled as Tails roll his eyes before turning to the other students. He look down to see both Aizawa's and Vlad King's unconscious bodies. "What happened to these guys?"

"These are on teachers. They'll badly injured." Hiryu said, looking down at his teacher.

"Teachers? You mean these guys that are wearing costumes like y'all are your teachers?" Sonic asked as they nod their heads except for Momo.

"If your students, who's in charge then?" Tails asked.

"I am if your asking." Sonic and Tails turn around to see All Might standing in front of them, still not smiling. The two had their jaws dropped to the floor. The hedgehog pulled out the All Might Action Figure. Looking back and forth between the toy and the real thing, he finally found out it wasn't a dream.

"I-It's… him… it's him… it's All Might..." Sonic said, stuttering at the same time.

The students were stunned by that reaction. Momo and Itsuka were even more surprise than their classmates. First they were stunned when Sonic and Tails knew Izuku within a minute. Then with All Might appearing, they were more surprise that they know the Symbol of Peace. They watched as All Might took a knee to talk with Sonic and Tails.

"I take it you're Young Midoriya's Friends. He told me all about you two. It's good to see you." the hero said.

"I-I-It's good to see you to, Mr. All Might… sir." Tails said as they shook their hands with him.

"Yeah. Never thought we meet you in person at a time like this." Sonic said as All Might turn to see Izuku's injured body.

"I'm sorry we couldn't meet like this with all the villains invading the USJ. On second that, how did you manage to find this building?" All Might asked.

"We saw the Chaos Emerald that we gave Izuku a while back growing from our Chaos Emerald Radar. The power source from the emerald was so strong, we notice Izuku was here. Speaking of it, where is the emerald?" Tails asked as All Might pulled out the emerald.

"Sorry about it. Unfortunately, Young Midoriya use all this take on everyone here. He was so close at beating that creature that I hold on to the monster for him to beat. Sadly, the emerald ran out of power and Midoriya couldn't beat him." He said.

Sonic look back at the villains that were unconscious thanks to Izuku. "So he manage to take everyone on by himself? Now that's a true hero for sure." He thought before turning back to All Might. "And I guess that's why Izuku got hurt by the monster because the emerald turn black."

"Exactly. Wish I would've been here quicker than doing my hero work. Another rookie mistake I made." All Might said, putting his head down in shame.

"Don't worry about it. It's not your fault. You should be grateful I'm here. Besides, if you don't mind, I like to get a shot at that big monster behind you." Sonic said with a smirk.

"WHAT?!" the student yelled in shock.

"You can't be serious? Did you saw what that thing did to our teachers?!" Mineta yelled.

"You have to be that insane to take on that thing!" Shoda yelled.

"You'll be just like Izuku!" Momo yelled as Sonic look on at the students with a smile.

"Hey, I've been though worst for the past couple of years. I took on monsters and robots and I always thrilled in situations like these. Relax, I'm gonna win and that's a guarantee for sure." He said, giving a thumbs up.

"He really is that crazy." Kaminari said.

"Trust him. He will win. I know it." Tails said turning to All Might.

"Very well then, If things get out of hand, I'll get in and help you out. Just be careful." All Might said.

"Don't worry. I'll be fine. Just watch over Izuku." Sonic said as he walk over to where the villains were. "Hey! You three bozos over there! I'm calling y'all out! I'm gonna win this thing for sure! Just want to let you know if you're scarred to take me on!"

"Really, you pest! You got yourself a big mouth! But don't worry, my Nomu will crush you alive! Once and for all!" Shigaraki yelled before turning to the beast. "Nomu, make sure you deal with him before we deal with All Might."

The Nomu roared as he jumped in, ready to fight against the hedgehog.

"This is gonna be fun." Sonic said with a smile.


Back at the Collapse Zone, many villains were getting more and more pounded by the day. Bakugo, Kirishima, Tetsutetsu, and Awase were destroying everything in their path as they were making their way to the exit of the zone. More villains continue to appear, trying to block their way. But the boys continue to use their Quirks to quickly beat them like before.

"These guys don't quit do they?" They should we're stronger than them!" Tetsutetsu said, using his Iron Quirk to KO'ed a villain in the face.

"They're ignorant because we're students! DIE!" Bakugo yelled, using his Explosive Quirk on three villains, sending them flying in the air.

"That should be the last of them! Let's go before more shows up!" Awase said as they proceed to the exir. They would see four more villains waiting for them with weapons in their hands. "Crap! Heads up, we got more villains blocking the exit!"

"Guess will give them more pain!" Kirishima yelled, activating his Harden Quirk in both arms.

The boys activated their Quirks, charging towards the villains at the exit for another attack. The villains grin evilly, ready to use their weapons on them. Suddenly, everything was rumbling. The boys stopped their charge to look around. The villains did the same as they were confused to felt the rumbling. Almost like an Earthquake was happening. But this wasn't no Earthquake. Then, out of nowhere, an echidna popped out from the ground where the villains were. Creating a hole for them to fall in to. The boys were stunned when the echidna appeared in front of them.

"Well, that was quick. This echidna still got it." Knuckles said, stretching his arms out before turning around to see the boys. He got in to his defensive stance. "Where you guys came from? You're not one of them aren't ya?"

"Hold up! Don't attack! We're not bad guys! We're students!" Kirishima yelled, waving his arms around.

"Students? Hold up, students that are becoming heroes?" Knuckles asked.

"Yeah, that's right. Wait, how you know that?" Kirishima asked with a curious look before shaking off that topic. "You know, never mind. Anyway, that was awesome you just did. You popped out from the hole and trash those guys. Must be a neat plan you did."

"I was just entering the building when I heard what was happening with two of my friends." Knuckles said.

"That's interesting. Anyway, the name's Kirishima." He said, giving a handshake to the echidna.

"Knuckles the Echidna. But you can call me Knuckles. Or Knux if that's what you want." He said, shaking hands with Kirishima.

"That's an awesome name by the way." He said as Tetsutetsu and Awase also shook hands.

After that, Knuckles turn to Bakugo who want it to shake his hand. Only for him to be left hanging for Bakugo to walk pass him towards the exit after giving him an angry snarl. "Really, dude? After I save you from them, that's the thanks I receive?" the echidna asked.

"Like I give a damn about a little good for nothing that can dig and plant traps." Bakugo said, continue to walk.

"That good for nothing." Knuckles said.

"Easy dude. You know how he is. Always have that anger issues." Kirishima said.

"More like a jerk that needs to get his ass handed to him." Knuckles said, looking at Bakugo.

Suddenly, three more villains tries to ambush Bakugo. He was ready use his Quirk on them, only for a sheet of ice appeared out of nowhere, freezing three villains. The others and Knuckles were caught by surprise by the attack. Deep down, the echidna wish that sheet of ice got on Bakugo for payback by not saying thank you for saving him. They ran up to see non other than Todoroki, who walk on the ice like he didn't care if it was freezing or not.

"Idiot! Next time warn me when you do that!" Bakugo yelled at Todoroki. But the other didn't care as he was calm.

"Wonder who this guy is?" Knuckles asked, seeing the red mark on his left eye. "Wonder what happened to his face?"

"We're glad to see you." Kirishima said when he saw both Sen and Togaru with Todoroki.

"Sen, Togaru! You guys okay?" Tetsutetsu asked.

"We're fine. Thanks to him though." Sen said, looking at Todoroki.

"I think I found a ton of information on these villains. Including that big monster that also arrived. And I think I found a weakpoint." Todoroki said, turning to see the echidna. "Who are you?"

"Let's just said he's a friend." Kirishima said.

Todoroki told them along with Knuckles about the situatuion at hand. The part of where they were planning to kill All Might. That gotten the attention of the echidna. Once he finds both Sonic and Tails, he'll rely the message to them . For now, he and the others were heading to Central Plaza to find their classmates.


[Music: His World by Crush 40]

Back at Central Palaza, the fight between Sonic and the Nomu was about to get underway. All Might, Tails, and the others look on while both Shigaraki and Kurogiri look on, thinking it would be a win win situation for them since the hedgehog is just small and big talk. Shigaraki couldn't stand that smile look on his face. He want that hedgehog dead once and for all. But they didn't expect of what the hedgehog has some big tricks on his sleeves.

The Nomu charges towards Sonic. He jumped to try to stomp on the hedgehog. But Sonic cracked that smile on his face by jumping in front of the beast and landing by sitting on the Nomu's head. "Hey, buddy. You gotta do better than that in order to beat me. You're too slow." He said, taunting the beast before hopping off and did a flying kick on the back of its head, sending the beast flying in the water.

The beast flew out of the water, charging at the hedgehog again. Using his fist to hit him, Sonic did a backward boost to avoid the punch. He use the boost again by launching himself to the thing. Hitting him, destroying the slide at the Shipyard Zone. Then launches him in the air, deliver faster punches on the Nomu's Face. Then delivers the same flying kick, seeing the beast towards a rock where the slide was there.

"Yawn. I'm getting bored here. I thought this would be a good fight." Sonic said, turning to the main villains. "You call that your best guy? That thing couldn't land a single punch on me! You guys got a soft fighter!"

Shigaraki was growing in anger. Scratching both sides of his neck at the same time like before. "I'm starting to get annoyed by this rodent! Nomu, get up and squash this pest!" He yelled.

"Aw, did I hurt your feelings? Oops, perhaps you should go home to mommy." Sonic said, taunting him more.

"You little..." Shigaraki was triggered by his comments.

"Calm down. Don't let that pest get to your head." Kurogiri said.

"Shut up!" He yelled. "When the Nomu beat this pest, I will give the beating of his life like I did to that boy!"

The Nomu launched himself back in the air. It was getting more angry by the minute. It grabbed a rock from the slide at the Shipwreck Zone. He tries using as a weapon to take down the hedgehog. Sonic jumped right back in Central Plaza. He stood on the fountain, looking at the beast. He taunted him more by sticking his tongue out at him. The beast threw the rock at him. Sonic did a quick side step, avoiding the rock as it destroyed the fountain.

"Too slow, dude. Gotta do a better job at that." Sonic said.

As the fight continues, All Might did ordered early on for the students to carry their teachers to the exits, away from the fight at hand. Both Hiryu and Shoda carried Vlad King while Kaminari and Mineta carried Aizawa. Momo still held Izuku in her arms. Tsuyu look at the boy with a sad look. She felt bad and want to at least say thank you for saving her. But also apologizing for not helping him when he was being tortured by the Nomu.

While the students quickly exit from the area, both All Might and Tails look on at the battle between Sonic and the Nomu. The hero saw the fighting skills of the hedgehog. The same skills like Izuku did before. What he did like and funny was him taunting his opponents and getting under their skin.

"I have to admit. This hedgehog is fast. He has the same fighting skills as Young Midoriya." All Might said.

"He's been doing this for many years. I've look up to him as a sidekick where I learn all his moves. That's why I know he can win when he guarantee it." Tails said.

"What I do like is him taunting his enemies. Has he done this before?" All Might asked.

"Oh yeah. It's really funny to see him get under the skin of his opponents. They don't like it. But he does and it an advantage he takes." Tails said.

"Interesting." All Might said as he looks on at the fight. "Once this is over, I will like to have a talk with Sonic later on. He needs to tell me more about the emerald like I promise to tell him. For now, this fight is getting better. Sonic's Speed does matches against Young Iida's but the hedgehog's speed is way better. He might have a chance at winning this thing after all."

The Nomu tries to punch Sonic on the ground. The hedgehog did a sliding between his legs, dodging the punch. He stood up, jumping the air. The Nomu jumped in the air, trying to chase the hedgehog. Sonic does a power stomp, slamming the Nomu on the face multiple times before crashing back on the ground. Sonic rubs the dust off of him. He looks back seeing the beast on the ground, struggling to get up

"This is boring. You're not fun." Sonic said.

"See what I mean? That's the example of taunting." Tails said.

"I don't blame Young Sonic. It is a boring fight. If I was fighting it, it would be done within seconds." All Might said.

Both Shigaraki and Kurogiri were stunned what they were seeing. The mist figure could only look on with a shocked face. Shigaraki was more angry than shocking. He was confident the Nomu would win. But the hedgehog had other plans. Knowing this defeat could be a failure for the League of Villains and if he would sent in his minions, they would meet the same feat.

"That thing is at its weak state. You got a chance to beat this thing." Tails said, using the Miles Electric on Nomu to see its status.

"Don't mind if I do." It won't take long to finish this thing off." Sonic said, stretching his arms and legs out. "And once I'm done with this, I'm coming for those two next." He point his fingers at the two main villains before looking at the Nomu.

"Tails!" All Might and the fox cub look to see both Knuckles, Bakugo, Todoroki, Kirishima, Tetsutetsu, Awase, Sen, and Togaru arriving from the Collapse Zone.

All Might got a glimpse of Knuckles. He was the same like the Mystic Chief. "Another one? Must be a lost ancestor of this century. Need to talk with him about my meeting with his kind. Perhaps he knows more about the Mystic Chief." He thought.

"Knuckles, you made it just in time. Sonic is about take down that beast." Tails said as they see the beast in his weak state. They turn to the hedgehog with a shock face.

"Another one of your kind? This day just get weirder." Tetsutestu said.

"You mean that guy is about to beat that beast?" Aizawa asked with a shocked face.

"No freaking way! That little guy?" Kirishima asked, turning to the fox cub. "You know him?"

"Of course. Sonic's always unstoppable." Tails said.

[Music Ends]

The others observed the hedgehog's attempt for the final blow on the Nomu. Todoroki look on before turning to All Might about information he gotten from one of the villains he frozen. Bakugo look on and notice something familiar. He look at the hedgehog and notice the same six long quills behind his head, same blue fur, and same red shoes. It then hit him. Memories of the day he encounter Sonic after trying to bully Izuku during childhood.

"No way… that's him. The sewer rat that got in my way of trying to kill Deku! That bug was right! He did return!" He thought, clinching his fist in anger. "This is my chance at getting back him! Starting right now!"

Bakugo drew sparks in his hands before charging towards the hedgehog. The others saw that with a stunned look.

"What the hell's he doing?" Togaru asked.

"Sonic, look out!" Knuckles yelled.

The hedgehog use his speed boost to go for the final blow. He heard someone screamed at him when he turn around and saw Bakugo tries using his Quirk on him. Sonic dodges it and lands right back to his position. Bakugo stood on the other side.

"What the hell, buddy? I was about to beat this until you jumped in!" Sonic yelled.

"You don't remember me, sewer rat! The same person you got in my way of hitting Deku in the park!" Bakugo said in anger, glaring at him.

Sonic look at him. He could see the blonde hair he has along with that same angry look. Memories in Sonic's head flashed in his head. Going back to the day he saved Izuku from Bakugo. It finally hit him. "Bakugo I believe. Or as Izuku would say Kacchan, isn't it?" He asked.

"That's right. You finally find out who I am after all those years." Bakugo said.

The others look on with shocked faces after hearing that comment. For Knuckles, he was surprise that he didn't notice that it was the bully that Sonic told him. Tails knew about it but never met him when they were on Earth before. All Might knows much more since Izuku told him his history with the bully a while back including the part that Sonic save Izuku from Bakugo.

"Bakugo, what the hell you doing? That guy almost had this thing won!" Kirishima yelled.

"Shut the hell up!" He yelled before looking at Sonic. "What you did that day was embarrassing to me. I did said it ain't over yet when I get you back. Well, here we are now."

"Look, I ain't got time to deal with you. That thing is about to get back up and take us down if you don't get in my way." Sonic said.

"I could care less! You and I are gonna fight! So let's go!" Bakugo yelled, getting his fist ready.

"All Might, do something!" Sen yelled to the Symbol of Peace.

"Young Bakugo, stand down! Don't interfere in Sonic's Business! You can deal with this another time!" He said.

Both Shigaraki and Kurogiri were hearing the conversation unfold. Though it would be nice to hear more, it was the perfect chance to turn the tables around for the League of Villains. They saw the Nomu getting his strength back while both Sonic and Bakugo yelled at one another.

"The Nomu is getting back in gear. Now's our chance to attack." Kurogiri said.

"Nomu! Finish them now!" Shigaraki yelled.

The Nomu jumped to attack both Sonic and Bakugo. The two turn around to see it coming towards them. Suddenly, the roof ripped open causing the beast to stop its attack. Everyone in the building look up to see the outside world for the first time since being locked in. But something was covering the roof. They look to see a floating ship covering the sun. The door beneath the ship slides open and a large object came down on the ground. Among them, multiple EggRobos, Egg Gunners, Egg Pawns, and Egg Fighters dropping from the ship, landing on the ground. They all aim their guns with red lasers around. Other robots scattered around the building including some aiming their guns at the exits where the students were. Other robots aim their weapons at both Shigaraiki and Kurogiri. The other villains raise their hands in surrender.

"What the hell? Where these things came from?" Awase asked, looking around.

"We already know who it is." Knuckles said.

Sonic look up to see an object coming down slowly from the ship. When he saw it, he knew what it was. The Death Egg Robot landing on the ground where everyone saw it.

"That's one big robot!" Kirishima yelled.

"But who is it?" Tetsutetsu asked when a laughter was heard.

"And I guess we know who it is." Sonic said as he saw the hatch open up, revealing a familiar person. "Dr. Egghead is here in the party."

"HO HO HO HO! So I guess the party started without me!" Eggman yelled with his other minions appearing from other parts of the ship. "Well, Sonic. We meet again. I was surprise you didn't manage to finish me off in space like before."

"I thought I would not let you give up until the big battle up ahead. Since you're here, I guess the party just gotten much better." Sonic said as Eggman turn to see All Might.

"Hello there, All Might. We meet at least. Allow me to introduce myself. I am Dr. Ivo Robotnik. But you can call me Dr. Eggman." He said.

"How did you know me?" All Might asked.

"Well, let's just say those days when your being watched for many years along with your student aka Izuku Midoriya. The boy your training with before." Eggman said.

"WHAT?!" All Might asked in a shocking tone.

"Come on, now. Would I just go ahead and blackmail you if I ask t come along with us. I'm afraid not. Anyway, there's reasons why we're here and that is you and that Izuku boy. Where is he?" Eggman asked.

"That's none of your business, Egghead! Leave Izuku out of this! You're going after for the Chaos Emerald, correct?" Sonic asked.

"I know he's in this building and maybe I'll launch an attack around it so you can give it to me. I want the Chaos Emerald right now." Eggman said.

"I'm sorry but that Chaos Emerald and Young Midoriya is not your property. Get near him, you're regret it!" All Might yelled.

"Okay, then. You wanna play those games! So be it! Let me teach you how it's going to work, if you don't give me the emerald, I will have no choice but to robotized everyone here in this buildings. Heroes or Villains, you'll be masters to me!" Eggman said.

"Robotized? What the hell does that mean?" Awase asked.

"You don't want to know about that." Knuckles said.

"You see, All Might. You'll be my first victim as a weapon for the Eggman Empire. And what it Robotized you might ask? Let me give you an example." Eggman said, pressing the button where one of the claws on the robot wrapped the Nomu around tightly.

"What the hell's he doing to my Nomu?!" Shigaraki asked in anger as Eggman turn to the two villains.

"Don't think I've forgotten you two. Remember those words that you said in don't get involved in business? Well, you're involved in my business and this is what happens when people get in my business." Eggman said, pressing more buttons.

A capsule came down from his flagship. It activated by itself. Once the door open, he place the Nomu inside the capsule. Everything closed including the glass for no one to see. They could hear the beast pounding inside, trying to escape. Sadly, it didn't work. The capsule activates with lights. The pounding inside pause. Took a couple of seconds for the capsule to deactivate itself. The door slowly open, revealing steam. The beast came out from it and everyone was stunned when they saw what happened next.

"No way!" Tetsutetsu yelled in shocked.

"You gotta be kidding me!" Kirishima yelled.

The Nomu was turn to a robot. His arms was iron. It's face turn red with sensors on it. Teeth were made of metal. His brain was replace with a metal head.

"H-H-He turn… our creature… to a robot? That's impossible!" Kurogiri said in a shocking tone.

"My precious Nomu! My creation… its gone…. THAT LITTLE GOOD FOR NOTHING!" Shigaraki roared in anger as he jumped in trying to use Quirk on Eggman.

The doctor smirk by using the robot to slam him backwards to the ground. Kurogiri use his Quirk to teleport him safely back to the ground. "Are you okay, Shigaraki?" He asked.

"Shut up! How dare that man turn our Nomu to a robot!" He yelled.

"You see. That's the example of robotized. Now, this thing is now belong to the Eggman Empire. That's gonna be the same thing once I create my One World Government and everyone will bow down." Eggman said.

"That's insane. He turn it to a robot. I thought the villains that came here were dangerous. This Eggman guy is more dangerous than ever." All Might said.

"Since you want to play games with me. I guess I'll call in a special friend." Eggman said, activating his hologram with Snively on it. "Snively, is he ready?"

"Yes, sir." He answered.

"Bring him out." Eggman ordered.

"Bring who out?" Sonic asked.

Everyone look up to see a capsule coming down on the ground from the ship. Once it did, Eggman hit the switch on the yellow button. The doors popped out creating steam out of it. The others look to see a figure slowly floating out of the capsule, landing in front of them.

"Ladies and Gentlemen, please welcome. The Ultimate Mercenary. One of new weapons I've created that can help in the upcoming invasion of Earth. Say hello… to Infinite." Eggman said.

The Jackyl hold his mask with his hand until he removed his hand off it. He open his eyes to see the others looking at him with a shock face.

"So this is the planet Earth. And the day of Infinite will rule when I get rid of everyone on this planet… starting with the Symbol of Peace." He said, letting an evil laugh out throughout the building.

The Heroes thought they were almost home free. With the League of Villains failing, it was now Eggman's turn to strike and with the Ultimate Mercenary, a chance to send a clear message to Earth.


End of Chapter Nineteen

Author's Note: Another chapter is long done. I kinda feel like I rush in because I want to post this story as promise but it feels like I left off some suspense to add to it. Oh well, I can use that in the next chapter for sure. We're not perfect in this world. You know how that goes.

Anyway, the next chapter coming up will be the Season One Finale. After that, I'll probably do two or three Filter Chapters before we enter Season Two. So prepare yourselves, the big battle awaits from the Heroes now with Eggman and Infinite arriving in store. Also, this chapter is the final chapter of the month of March. Tomorrow will be entering April and it'll be just three months to the day I started this story. Just want to say thank you to everyone who stood by throughout the story. There's more to come. Stay tuned.

Review and give me questions on this chapter. See y'all in the next one.
