That Was It? Pt.2

Slight manga spoiler warning about Shigarki's origin

In parenthesis I'll signify where the spoiler is
================================

"I just really don't like villains."

Tsu and Mineta looked at Izuku and knew not to keep asking questions. 

They watched as almost effortlessly, Aizawa knocked out villains using his wrap scarf, that is, until a bird-like beast charged in. As it lifted its arm to hit Aizawa, it seemingly teleported into a wall. The teacher looked to where the creature previously was, and saw Izuku standing there with focused eyes deadlocked on the creature. 

"Kid I told you to stay out of thi-" 

"No. You were about to get hurt and I am NOT going to stand by and watch it happen when I can prevent it." 

Aizawa grinned and gave Izuku a nod of approval.

The villain covered in hands started laughing hysterically. "HAHAHAH, you're so cool kid! Being able to punch away my Nomu with a single punch! Hah, but it's nothing against its shock absorption and regeneration!" 

The Nomu stands up and stares lifelessly at Izuku. "NOMU! KILL THAT KID!" The villain laughs as the creature charges. As the Nomu throws a punch, Izuku ducks and sees it's fist fly over his head. 

With an instant kick to the Nomu's side, it's body flies into the hand villain. The hand covered villain starts laughing yet again despite being down. "You think a puny kid can defeat my Nomu like that? HAHAHAHA IT WAS DESIGNED TO KILL ALL MIGHT, WHAT MAKES YOU THINK THAT IT'S OVER JUST LIKE THAT!?"

Izuku looks as the Nomu starts to stand up. It's dead eyes move to look at Izuku's. He feels chills run up his spine as anticipation grows within him. "It looks like that crab villain from 3 years ago." Izuku grits his teeth and smiles. "Large Punch."

Everyone around Izuku flew backwards and through the walls of the USJ, as winds fought to escape the building. The roof implodes from the pressure, causing a boom that can be heard by the facility all the way at UA. 
The students and villains scatter into the forest surrounding the facility, as it's walls crumble into the wind. 

Izuku yells, as his fist collides with the one thing he truly despises. A product of evil with it's only purpose being to murder someone that gives the country hope that they are safe. Although Izuku has mixed feelings about the man, he knows that he cannot let All Might die. For the sake of the country. 

The punch ripples throughout the Nomu's body. Every wave of flesh distorts its body more and more as it's black blood-like substances are forced to burst out of it's skin. The creature splatters into the air, as small chunks of it's mutilated body fall onto the decimated floor. 

The winds carry the black liquidy chunks and splatter it against some of the students and villains. 

Bakugou grips the side of a tree as he looks from a distance. He squints due to the harsh winds, and makes out the image of Izuku. He flinches as he gets splashed in the face with a Nomu chunk, and represses an urge to vomit. As the winds die down, he whispers to himself, "Damn nerd."

The villain covered in hands, Shigaraki, begins to crawl around searching for a hand that once covered his face. His crazed eyes scan the area, as he mumbles the words, "Father." When he eventually stumbled upon it, he retracts his hand as a sharp pain fills his nerves. 

Shigaraki turns to see the hero Snipe with a smoking gun, along with an army of UA teachers, including All Might. The villain shouts at the number one hero, saying "I'LL KILL YOU ALL MIGHT! NOMU, ATTACK!"
