What is this?" All for One asked. He had brought Izuku to him again to discuss his progress and after the conversation the boy presented him with a box. When he opened it appeared to be some sort of metal mask the front of which resembled a crude skull with tubes attached to the back.
"It's a special helmet I made, basically it's like a portable life support machine you can wear", Izuku explained showing his invention off. "I wanted to thank you for believing in me sir, so I made this device so you could leave this room if you want, for up to an hour at least", he really wanted to help the first person to have faith in him. Even though he was a villain, he looked up to All for One.
"I should be the one giving you gifts", Sensei smiled. "I don't know what you said to Tomura a while ago, but it seems he's finally growing and thinking for himself"
"Yes I'm glad to see him properly motivated too", Izuku was happy mainly because Shigaraki didn't really need him much anymore to help plan things out. He was doing it all himself which left Izuku more free time in his lab. Which was good because he had to rebuild the Forge after it blew up creating the space stone.
"Are you sure you won't reconsider me giving you a quirk?" All for One repeated the offer he gave the boy when they first met.
"It's a very generous offer Sensei, the old me would have jumped at the chance, but I still have to decline", the boy smiled gratefully. "I want to prove my point to the world that quirks aren't as special or great that everyone makes them out to be. When I defeat Allmight, I want him to look me in the eyes and know that a quirkless kid that he deemed worthless like the rest of society beat him", Sensei chuckled at that. The kid was going to make a wonderful villain in the future.
"As you wish", All for One took the mask from the box and placed on the table by his side. It might come in use later. "Good luck with your internship Izuku", the boy flinched at, but quickly remembered that the man new almost all about him including what went on at his school.
"Thank you sir", Izuku bowed politely and left through the open portal.
MUSUTAFU CITY-NEXT DAY
"Here we go", plastering a smile on his face Izuku straightened the tie of his dark green suit. Today was the first day of his internship at 'Geonosis Tech', a large company that made support items for heroes, but most notably they were the ones that built battle robots and drones for hero school training. Apparently the villain bots used in the U.A entrance exam and sports festival were designed and built here.
First they wanted to see a portfolio of his designs then a demonstration of the devices he built so far. After that they would decide what they wanted to do with Izuku during the internship. According to his teacher Kinzoku he was the youngest student accepted into this company. They would either have him do basic grunt work or if they were impressed more advanced stuff.
Walking passed the large outdoor fountain Izuku approached the glass door of the tall building of Geonosis Tech carrying a metal briefcase. When he entered he ignored the extravagant lobby area and walked over to the front desk.
"May I help you", the man behind the desk.
"Izuku Midoriya. I'm here for the internship", He smiled pleasantly.
"Ah yes, right this way", the man escorted Izuku to the elevator. While they were going up the escort tried to engage the boy in conversation. "Are you happy to get an internship in the second largest hero support company?"
"Indeed I am?" Very happy in fact. This was the gateway to achieving his ultimate goal. The League of Villain's resources were starting to run dry for him. Plus Izuku needed another location to work on his infinity stones. If he could gain the company's approval and trust then he would have it.
The elevator opened and the two stepped out. The escort led him to the research and development department where the presentation would take place. Izuku breathed in and out as he prepared to act his way into Geonosis Tech. Compared to what the company normally produced he knew that his devices should more than impress.
LATER THAT NIGHT
"So how do you intend to change things?" Stain asked. They were both sitting on a roof top in northern Musutafu city waiting for the target to arrive. In the envelope that Izuku gave him he offered him information on fake heroes he planned to eliminate in exchange for letting the boy tag along with him when he killed them.
The first one they took down was the magnet hero Magnetron. Izuku helped Stain lure him to an area devoid of any metal and the man killed the hero with a thick plastic yet sharpened to a point sword that the boy made for him.
The second was the crystal hero Mosaic Man. A flashy hero that loved to show off. The man had a quirk that let him manipulate and create glass. It was a simple matter of chasing him down into an underground tunnel, where the least amount of glass could be used and Stain cut him down like an animal.
"Well let's just say I'm currently building a weapon", Izuku began taking a sip of his drink. "A weapon that will make me the most powerful person in the world"
"More powerful than Allmight?" The hero killer questioned skeptically.
"Definitely more powerful than Allmight", Izuku confirmed. "So powerful that everyone would have to do as I wished and any who don't conform to my standards of being hero well…they'll be retired", he said that word retired very ominously.
"You have guts kid", Stain grinned. "I like this plan, it's so simple yet brilliant"
"Oh look at that our target's coming", Izuku remarked looking through his binoculars. Low and behold flying through the night sky Christopher Skyline A.K.A Captain Celebrity. An American hero who moved to Japan because of some trouble he got into back in his home country. A very arrogant man that only cared for his popularity. A prime target for the hero killer. Unfortunately his quirk Flight would make him difficult to catch.
"Time to start the show", Stain grinned as he grabbed Izuku by the collar of his shirt and pinned him to a wall behind them.
"Here I go", Izuku cleared his throat and started screaming as loudly as possible. "PLEASE DON'T KILL ME!" He cried letting tears fall down his face.
"Time to die scum", Stain placed his blade against the boy's throat.
"Halt villain!" Like they predicted Christopher Skyline appeared levitating over the building above them. Diving in with a quick smack he knocked Stain away and grabbed the boy hovering with him out of harm's way.
"Thank you so much! He was trying to kill me!" Izuku sobbed while thanking his savior.
"Not a problem child", Christopher spoke in very poor Japanese. "You must be the hero killer Stain. Picking on young children now", the killer just grinned seeing the kid's plan come together in front of him. Suddenly the American hero felt a stabbing pain in his side. Which was appropriate since he just got stabbed there. Izuku freed himself from the hero's hold and leaped safely back on to the top of the building while Captain Celebrity clutched his bleeding wound.
"Would you care to do the honors?" Izuku smiled as he handed the blood covered dagger to Stain.
"With pleasure", the killer took the small blade and licked up a single drop of the crimson liquid. Christopher didn't understand what was going on until his body suddenly became paralyzed. Unfortunately with his body frozen he lost control of his quirk and went plummeting down the side of the building.
"Bye bye!" Izuku waved as he went straight down. "Can you believe that scum got away with sexual misconduct by fleeing to japan?" He said as he approached the edge to look where the body landed. It was fifteen story fall so he was either dead or his career would be over with. "Definitely dead. Looks like he landed rather awkwardly", he made a face of disgust.
"Good riddance", Stain spat while handing the dagger back to his partner as per the agreement. Izuku thanked him and wiped the excess blood off the blade placing the rag in a zip lock bag for later. The quirk Flight would be useful to him, hence why he was here helping Stain.
"Well this was fun, but I'm afraid we need to depart for a while" Izuku told him. "I got to get to work on my weapon, so I won't have time to do much villain work".
"Do you really think you can change anything with this weapon of yours?" Stain wasn't asking with complete honesty this time giving him a serious face.
"Not only will I change the world, but I'll do it with the least amount of violence and bloodshed", Izuku promised him.
"Now that's impossible", the killer chuckled at the kids naïve promise.
"Are you a betting man Stain-San?" Izuku inquired.
"I only gamble with my life", Stain said.
"How about this. I bet you that I can defeat and end the career of the number two hero Endeavor without killing or crippling him", Izuku offered. "If I can do that would you agree to come work for me?"
"Without killing or crippling Endeavor? You think you can end him?" Stain didn't sound like he thought that was possible.
"If it was easy then it wouldn't be a challenge" Izuku smirked at him. Giving it some thought Stain decided to agree to this bet.
"What do I get if you can't do it?" The hero killer asked.
"All my notes and analysis on any and every hero you want", He had an encyclopedic collection of notes on heroes. With that information Stain would become an even greater and more effective hero hunter.
"You've got yourself a deal", Stain said. He had seen the boy's intellect first hand and would love to pick his brain for information on more fake heroes.
"See you at the finish line then", Izuku pressed a button on his wrist device and a portal opened behind him. It looked similar to Kurogiri's warp gate but this one was different. Firstly it wasn't made of dark mist and it appeared to be held open by some sort of blue electric-like energy. He waved goodbye to Stain as he stepped through the portal.
When he arrived in his lab he frowned seeing the device he attached the space stone exploding in sparks. It seems his calculations were correct. The stone only worked with a living organism. Any device that tried to force the power out would explode. All that power needed a living body to let the energy flow into.
"At least I know it works now", Izuku sighed as he removed the stone from the destroyed machine and placed it safely in the small vault he created to protect it until he could build the Infinity Gauntlet. After that he took the sample of Christopher Skyline's blood and placed it in the D.N.A analyzer. Izuku then took a seat at his computer and began typing away. He was only interested in the maneuverability of and levitation that the recently deceased hero's quirk possessed. Izuku was hoping it would make a good substitute to Ochako's zero gravity quirk for the reality stone, since he missed his opportunity to get it that time at the mall. He liked her hero spirit too much to physically attack her in public just to get a blood sample.
Putting the quirk genetics together in the computer simulation was becoming more and more frustrating. Especially for the reality stone. He kept putting together telekinetic quirks and matter manipulation quirks together, but it still always fell apart in the computer no matter which way he built it. There had to be some way to balance it out. On the plus side if he added Kinzoku's metal bonding quirk then he could use the reality stone to generate a new type of metal that would be perfect for the gauntlet.
Sadly the solution still alluded him. The time stone too. He always came really close with it, but it still fell apart in the genetic simulation. Sensei gave him an interesting idea on whose quirk he should use for the power stone, but getting a sample might be a bit difficult. So that one was on hold for now. The soul stone was also a mystery, but he did have one quirk in mind. It's just that getting a sample is unthinkable at the moment.
'If it was easy then it wouldn't be a challenge' Izuku needed more D.N.A. to work with if he was going to make more infinity stones.
Short chapter I know. It's pretty much just filler. They was actually going to be more in that internship part, but I cut it out. It was mostly just a bunch of techno jargon with Izuku talking about his designs and inventions. There's going to be a lot of that in the next chapter so I decided to save it for then.
