*Spoilers!!! Spoilers!! This is a WARNING*

This is a My Hero Academia one shot.... two part thing.

Just an idea I had while being on Pinterest and looking at pictures. I'll show them to you if you want when this is finished. This takes place after season 4 and after the manga volume 20.

(Because that's where I am. :D )

For now....

Enjoy!

'There are many times we come to a crossroads in our lives, and sometimes we don't fully realize what our actions do. What the consequences will be because of our actions....'

'A small word can throw someone over the edge, or a small careless act can send someone spiraling out of control. No matter how small that action may be...'

'They call it the butterfly effect. I call it the cruel twist of fate...'

The clouds slowly gathered across the sky as people in the city went about their business and talked about a few recent events. The school festival had just ended and people were still gossiping about what happened and taking to social media and discussion boards on what they liked.

The school was now talking about going to an expo where some scientist from I-Island would showcase a few inventions. It would be taking place in a museum in the city. Everyone was excited and made sure to have their slips signed off for the teacher.

All Might sat at his little desk and stared at the paperwork they filled out so they could go on the trip. He sighed and rubbed his face a bit. He was a bit upset he wouldn't be able to see Dave and Melissa, but he preferred that they stay safe. He looked to the other teachers who were coming as well and then glanced to his phone as he got a text. He smiled a little as young Izuku said hello to him.

"Are you coming or what?" All Might looked to the voice, and jumped as blood spurted from his mouth. He looked at Aizawa as he lay on the floor in his sleeping bag.

"Why are you in that?" The tall blonde asked as he furrowed his brow. "Have you been sleeping here the whole time?" he said and his friend rolled his eyes.

"No. I just didn't want to get out of bed but have to be here." he sighed and closed his eyes as he grumbled. All Might smiled a little and got up then looked at him before glancing around.

"Who else is joining us?" he asked and Aizawa sighed again as he sat up then stood and glanced around.

"I believe most of the classes but we're all assigned to stick with our own class and keep them out of trouble." he muttered and glanced to the clock. "Let's go." he sighed and walked out of his sleeping bag then picked it up and left the room.

All Might smiled a little as he watched him then looked at his thin hand. He wished he could help in his hero form. He shrugged and followed after the other man to the dorms where the children were waiting.

"Everyone get into an orderly fashion!" Iida shouted as he made hand motions to make sure they knew what order he meant.

Bakugo grumbled as he did as told then wandered. Some of the girls fixed their uniforms and talked to each other. The teachers came over and looked around at the students standing in line, ready to go.

"Okay everyone hand in your slips and get on the bus... let's get this over with." Aizawa sighed and looked at them. All Might stood by him as they stood at the bus doors.

Each student walked by and handed in their permission slips. Mina panicked when she couldn't find hers but eventually did. They all got on and found spots to sit as they talked excitedly.

"Is everyone on the bus?" All Might asked as he looked around then went to count the students inside. He had counted them about ten times before they even got on.

"If they aren't they won't be coming." Aizawa shrugged and sat in the front as he sighed and closed his eyes. Not wanting to do this right now.

All Might counted the students ten more times then finally sat down and sighed in relief. They finally headed out and the teens talked about the expo the whole way there. Once they arrived at the location they filled out and Aizawa gave them instruction before they went inside.

The student's were greeted by some staff and they gave them a small introduction before they led them inside. The student's of UA would be the only ones visiting that day before the exhibit opened to the public later. The other classes would be arriving one after the other.

Aizawa glanced at his watch as he checked to see how much time they'd have before the next class came in. Class 1-A was one of the last classes on the museums schedule. They finally went into the section and gasped as they looked at the different inventions.

"Now we again ask that no one touches anything." The host said and looked at the students then frowned deeply. "We don't want damaged inventions when this event hasn't even started." He huffed and Bakugo rolled his eyes as he scoffed.

They wandered in and looked at a few things as they gasped and looked at each other. The girls giggled at a few things as they walked in groups and the boys admired a few other gadgets that grabbed their attention. Aizawa and All Might wandered around with them as they looked at a few things then talked about their time they had. The blonde man noticed the boys looking at one invention and he walked over to check on them.

"Look at this one, it's self cleaning and can help get rid of pollution or garbage." Izuku smiled as he watched it then looked at the teacher as he came over.

"I doubt it can do all that." Bakugo huffed and poked at it, only for it to squirt oil at them, they yelped and dodged but it hit All Mights yellow stripped suit.

He blinked in surprise and looked at his now ruined jacket and pants. They stared at him and hesitated as they felt bad for destroying his favorite outfit. Aizawa and the host came over then gasped as they saw what happened.

"I'm so sorry Mr. All Might, I'll find you something suitable to change into... but I only have my workers uniforms." The host fretted and All Might chuckled.

"That's okay. I don't mind." he said and the host led him off so they could get him something to wear as they worked on fixing his suit.

He came back wearing an engineering jumpsuit that was unsurprisingly, too big on him. The girls giggled and squealed a little, saying how he looked so cute in the outfit. He raised an eyebrow and furrowed his brow a little. He wasn't sure how to take that and they headed out back to their tour.

As they walked the boys started to challenge each other as they got bored, but Iida set them straight as he lectured them a little. They ended the tour by coming to a robot called the Villain Buster. They gasped and stared at the massive machine as it's inventor worked on a few things.

"No stay back, stay back." the man huffed as he fiddled with a few controls and typed a bit. The robotic suit was about twelve feet tall and looked quite impressive. "This is sensitive material and very delicate." he scolded them as if they were little kids.

"Excuse me? But what's it supposed to do?" Uraka asked as she raised her hand a little. The man looked at her and fixed his glasses then flipped his hair.

"Why, it does exactly as the name implies." he smirked as he folded his arms. "It tracks villains and locks them away." he said smugly as he flipped his hair again.

"Someone is full of it." Kirishima smirked at Denki who snickered a little and the man glared at them.

"As I was saying this robot is power full enough to take on the nastiest villains out there. Including All for One." he said and they gasped in surprise, he liked that reaction. "Heck it could take on the League of villains or even All Might." he bragged and the students fell silent. The man looked to the thin teacher and cleared his throat. "Sorry sir." he muttered. The blonde just stared at him for a while then glanced around, feeling a little awkward. The scientist then started to tell them about what it could do and how it functioned.

"Enough talking, when can we see it in action?" Bakugo huffed and folded his arms. "Let's see it fight something!" he grinned. Izuku frowned as he looked at him and some of the other boys cheered a little.

"Unfortunately, it's had a few bugs so we won't be showing it off today." The scientist huffed and glared at them. They all looked disappointed and sighed as the scientist huffed again. They listened to his boring presentation and looked around at the massive bot.

"Hey Midoriya." Mineta whispered and the taller teen looked at him. The short young man wiggled his eyebrows and looked at a woman as she came in wearing a lab coat.

She fixed her glasses and looked at the green haired boy. The other boys watched her and she winked at them. Midoriya blushed and Mineta glared at him.

"Ah Amber, there you are." The head scientist said. "Please run a diagnostic on the program." He muttered and she nodded before going to the computer. The boys watched her and she then motioned for them to come over. She pulled out a flash drive and plugged it in.

"Do you boys want to watch?" She asked and they nodded quickly. She giggled and smiled as she worked on the program. She explained how it worked and stepped back then looked at Midoriya. "Want to help?" She asked and the boys glared at him as he blushed and stuttered.

He nodded and she told him what to type and how, then he hit enter as instructed. She smiled and they were called back over to the others. As they walked, the robots eye glowed as it turned on. They stopped and gasped as it slowly moved it's eyes and scanned the area.

Midoriya and the others grinned as they watched, but the green haired boys smile slowly faded as he realized this wasn't normal. He looked at the frantic scientist and then at the computer as it smoked and fried itself. He looked around for Amber but didn't see her and his eyes fell on Toshinori. The tall blonde and Aizawa also realized the situation was about to get bad.

"Iida! Lead the students to the exit!" Aizawa shouted as he gripped his scarf and the scientist yelled for help as he panicked.

The robot broke free as the students ran towards the exit, though Bakugo argued and wanted to fight the thing. The massive machine moved forward and hit the ceiling as it blocked their exit, luckily some got out of the room.

"Get outside to safety!" All Might yelled to the students on the other side. They nodded and quickly left to get some help. "Bakugo! Iida! Get out of here with the others!" He shouted and moved away from the foot.

"Don't tell me what to do Old Man!" The angry blonde yelled but helped them move across the room to get to the exit on the other side.

He paused as he and Midoriya looked back at their teachers. Aizawa had it tied up and All Might was helping the scientist get to the side exit. The robot looked around and made a rope similar to Aizawas scarf.

"Yes! It's learning! That part finally works!" The scientist grinned as he watched and All Might blinked in surprise as Aizawa avoided a fist as it came down.

"Now is not the time to celebrate your works functions!" Eraser Head shouted at him as he jumped away again from a fist, but got pinned down by the other. Bakugo growled and shot at the giant robot, he wasn't going to watch his teacher get snapped apart again.

"Die!" he yelled as it turned to look at him and let go of his teacher. He fired big shots to try and get it to stop, but had little to no success.

Aizawa coughed as he was winded and tried to breath for a second. Toshi helped the scientist get out and looked over to the others, the robot was putting it's fists together to smash Bakugo.

He knew he couldn't run in this form and turned into All Might. It hurt like hell and he made himself run towards his student, hoping he made it. Everything hurt and felt as if it was tearing apart inside of him.
