"Midoriya?" Iida asked.
"Don't worry Iida, I'm going to save you!" Izuku declared, "Can you move?"
"No, I haven't been able to move since he cut me," Iida said.
So, he has a paralyzation quirk related to cutting people. That explains all the swords, and how he was able to defeat so many pros without being caught, Izuku thought, Wait, is that Native? Crap, he has two victims here, if it was just Iida I could carry him to the street, but I can't just leave Native here! If I could lift more with Black Whip I could move them, but I can barely lift a chair.
Izuku took out his phone behind his back and sent his location to all his contacts, hoping someone would appear quickly enough to help him save Iida and Native.
"You came to save your friend," Stain commented, "You seem like a real hero, and I usually don't target children, so I'll let you leave."
Izuku quickly rushed towards the Hero Killer, and Stain started to raise his sword to stop him. As soon as Izuku was a meter away from Stain, he teleported behind the Hero Killer and punched him in the back, sending him sprawling to the ground.
"I'm not going to abandon people who need my help!" Izuku shouted at Stain.
"So, you teleport, huh?" Stain asked, "You're going to be annoying to deal with!"
"Midoriya, leave!" Iida demanded, "This isn't your fight!"
"If you think I'm going to leave because of that, then why are you trying to become a hero?!" Izuku asked.
Iida went silent and the Hero Killer rushed at Izuku. When Stain got too close, Izuku teleported above and behind him and sent a punch at his head, slamming him into the ground.
He has to be getting used to my teleportation by now, I need to do something different to keep him from finding a way to hit me,
Izuku then kicked the ground, shattering the part under his feet. He crouched down and picked up the larger pieces of concrete that had become separated from the ground and began throwing them at the Hero Killer.
Stain tried to dodge, but eventually, a piece hit him in the chest and knocked him back down to the ground.
Stain recovered and dodged the remaining projectiles before throwing a knife at Native.
"Are you going to save him, or are you going to avoid getting hit?" Stain asked.
Izuku responded by releasing Black Whip and using it to grab the knife before it could hit Native. He then directed the tendril holding the knife to stab Stain in the shoulder before he could realize what was happening.
"Both," Izuku said once the knife was embedded in Stain's shoulder.
"What was that?" Iida asked.
"My quirk mutated," Izuku answered.
"You are a true hero, " Stain said as he pulled the knife from his shoulder and immediately fell to the ground, revealing Uraraka behind him with her hand outstretched. He was then encased in ice as Todoroki walked past Izuku.
"You should probably send more than just your location next time, Midoriya," Todoroki remarked, "Although you didn't really need the help."
Uraraka then tapped the block of ice containing Stain and shifted its gravity upwards for a second before canceling its gravity, suspending it in the air. She shifted its gravity to follow her as she approached the other three teens.
"Thanks for showing up," Izuku said.
"None of you needed to be here," Iida exclaimed, "Defeating Stain was my responsibility for what he did to my brother!"
"You were doing a great job at that before we showed up, weren't you?" Todoroki asked after noticing the cuts all over Iida.
As they talked, Iida realized that his paralysis had worn off, and he stood up. Native, seeing this, also stood and approached the group.
"Thank you for saving us," the hero said, "We should probably move Stain to the streets to get another pro's attention. None of you can take him to the police, and I need to go to a hospital."
The five all walked out of the alley with Uraraka shifting the ice block's gravity to make it follow them.
When they reached the main street, they ran into Endeavour, Nighteye, Gran Torino, and Gunhead.
"When I said you had permission to fight," Nighteye started, "This isn't what I had in mind."
Izuku opened his mouth to speak, but a winged Nomu swooped down and grabbed him.
Endeavor started aiming, only for Gran Torino to smack his hand aside, "You'll hit the brat if you try to take the Nomu down!"
Uraraka released her quirk on the ice before tapping herself and flying after Izuku.
Izuku teleported out of the Nomu's claws and onto its back before sending Black Whip towards the ground. Once the tendrils had reached the street, Izuku used them to start pulling himself, and by extension the Nomu, down. As he was going down, he noticed Shigaraki and Kurogiri standing on the tower the Nomu was flying towards.
Once he and the Nomu had crashed landed, Izuku using the mindless villain to cushion his fall, Izuku teleported up to the tower to fight Shigaraki and Kurogiri.
"You again?" Shigaraki asked as he stretched out a hand to disintegrate Izuku.
Izuku teleported behind Shigaraki and punched his back, knocking him into Kurogiri and knocking them both down. He tried to keep them on the ground with Black Whip, but Kurogiri created a portal under them to let them escape to another part of the roof.
Shigaraki charged at Izuku again, but Izuku flicked, creating a gust of wind that blew Shigaraki off of the tower.
Kurogiri started creating a portal under Shigaraki, but before the portal could form, Uraraka crashed into him, distracting him too much for the portal to stay open, and Shigaraki continued falling. Kurogiri quickly created a portal and went through, allowing him to escape.
-Line Break-
When Uraraka had released her quirk, the ice holding Stain had smashed, freeing the Hero Killer.
Looking up from the ground, Stain saw Endeavor staring at the falling Nomu. He quickly stood up and stabbed Endeavor in the spine.
"You're the biggest fake of all of them," Stain told Endeavor as he fell to the ground.
Having said his piece, Stain allowed the bloodloss and frostbite to catch up with him and promptly collapsed to the ground.
-Line Break-
Half an hour later, Shigaraki had been taken to prison, and the pros and their interns were at the Hosu City Train Station, waiting for trains to take them to their home cities. Except for Endeavor, Iida, Native, and Manual, who were at the hospital, and Gran Torino, who was going to Nighteye's agency with Izuku and Nighteye.
"You've had an eventful internship, haven't you?" Uraraka asked Izuku, "Training a new quirk, learning to predict opponents, and fighting the Hero Killer and Shigaraki in one week?"
"Yeah, it's been a long week, but I need to work hard to become the number one hero!" Izuku exclaimed, "How has your internship been?"
"Oh, it's been great," Uraraka answered, "Gunhead has been teaching me close combat fighting, especially against people with weapons!"
"That's perfect for you, you're quirk requires physical contact, so you can't use a far ranged weapon. Most villains are equipped with a knife or a gun, so knowing how to get close to them would be invaluable for you, especially if you learn to use the weapons you disarm people of. Weakening the villain and strengthening yourself is more helpful than just weakening the villain. Although-" Izuku started.
"Deku, you're mumbling again," Uraraka interrupted.
"Oh, sorry," Izuku quickly apologized.
"It's fine, you're cute when you mumble," Uraraka said.
"What?" Izuku asked as his face turned bright red.
"Nothing!" Uraraka exclaimed as she brought her hands up to hide her blush, only to accidentally activate her quirk and floated a few meters upwards.
"Uraraka!" Izuku shouted worriedly when he realized what had happened. He quickly activated Black Whip and used it to gently pull her back down to the ground, where she deactivated her quirk.
-Line Break-
Alright, so the Stain fight is over, and we start to see why I gave Ochako One for All. It's going to be almost impossible for anyone without One for All to keep up with Izuku pretty soon. Even in the anime, Izuku nearly beat Bakugo at 8% with just one quirk.
Add Black Whip, Float, Teleport, and 4 more quirks, and then make One for All 5x stronger, and you've got the Izuku in this story (He's currently using the equivalent of 10% of the canon One for All, for anyone who forgot).
Now, with Ochako having One for All, she'll be able to keep up with Izuku, so he has a rival who won't become obsolete by chapter 20.
Shoutout to Dogium for guessing that Ochako was going to show up, half-shoutout to acosta perez jose ramiro for guessing Shinsou, who I initially planned to include in this chapter.
Also, thanks to MyOwn2Cents for influencing a bit of my plans for the next chapter!
