Chapter 4: Human Monster vs Hero Killer

Izuku walked away from Dabi's place after staying for a good while. He watched only until Eri lost her match against Dabi's brother.

It was a good and fun, Eri knows how to fight without using her quirk and from what he and Dabi could see, she motivated him to use his fire. After Dabi explained why that was a problem in the first place, his respect for the girl increased.

It was still early and there still too much light. He looked at the sky and noticed some sounds coming from an alleyway. He looked there and saw some hero in a knight costume, arresting someone.

He grinned. Time to shine.

Tensei Iida turned to the entrance of the alleyway, and saw Izuku "Don't worry kid, there isn't anymore trouble here." He said, thinking he came here worried of the screams of the thief.

Izuku scoffed "Oh thank goodness. But there is a problem that you need to deal with now." Tensei raised an eyebrow behind his helmet.

"Which is? Someone is in trouble?"

Izuku grinned cruelly "Yeah, the problem is me, and you are in trouble."

Tensai used his quirk to jump back from the fist aimed to his head. "Not bad! You actually dodged it!"

"A villain... very well! I'll take care of you too!" Tensai went forward at a great speed and Izuku threw a forward punch, but Tensei jumped to dodge and elbowed the side of the head of Izuku, sending him crashing to the concrete floor, head first.

Tensei landed and turned around to be kicked in the ribs sending him crashing to the wall. Izuku stood up, blood falling from his temple getting in pose "You actually caught me by surprise. Not bad... not bad at all. For an amateur that is." He mocked as Tensei came out of the hole of the wall holding his side, with his armor dented.

Tensei shot himself forward and threw a roundhouse kick with his right leg, only for Izuku to grab it with his left hand, and with his free hand, he covered it with the blue aura and punched him with his open palm on the chest denting the chest plate, before throwing him to some trashcans.

Tensei coughed blood. He probably, no definitely has broken ribs. He slowly stood up and was sent feet away from the punch he received on the right side of the face.

"Never mind what I said before... you are just like the rest." Izuku mocked as Tensei managed to stand up in shaky legs making Izuku smirk "Still want more? Good by me."

"Recipro...Burst!" Tensei screamed as he went towards Izuku at insane speeds. Izuku didn't have time to react as he was punched on the face. But before Tensei could move away, Izuku grabbed his left arm, and with his free hand, connected a right punch on Tensei elbow, breaking the arm and the engine.

Using the speed of Tensei, Izuku grabbed the back of his head and smashed it against the floor.

Over and over again.

Tensei helmet was destroyed and Izuku watched his broken face with a smirk. His nose was bloody and his temple was bleeding, but out of that, he is fine.

He let go of Tensei's head and was going to walk away, when he caught a knife aimed at his head.

He looked from the corner of his eye, crouched on the stairway of the building, a figure in red, black hair and red eyes glaring at him.

Izuku dropped the knife and smirked at him "Stain... long time no see."

Stain jumped down and glared at Izuku "You took another one of my preys... I'm getting tired of that."

Izuku grinned "Oh really? What are you going to do about it?"

Stain took out his katana and Izuku got in stance, his hands covered in the blue aura and Stain in front of him grinning.

Stain threw another knife at Izuku that slapped it away and jumped back to dodge Stain slashing. Izuku aimed a fist to his head and Stain that tilted it slightly and took a knife and made a cut on his arm.

Stain was about to lick it, when Izuku grabbed his wrist and with his open palm slapped Stain in the face sending him towards a wall, letting go of the knife.

Izuku smirked "You still cross that I won't help you in your 'noble' cause?" He mocked and Stain threw three knives at him. Izuku slapped two away and kicked one upwards.

Stain caught the last one in mid-air and went to stab Izuku in the stomach, but he sidestepped and went for a roundhouse kick. Stain switched his hold of the knife, and stabbed Izuku on the thigh as the kick connected sending him steps back.

Izuku took the knife out of his thigh with a hiss of pain and threw the knife away. He smirked as he saw Stain bleeding from the mouth and nose "What's wrong, Stain!? Can't beat a brat?!"

Stain smirked as he jumped to Izuku and swung his leg to kick him, Izuku blocked the attack with both arms, and Stain used the opportunity to slash Izuku's chest with his sword.

Izuku took a step back, as blood started to flow from the gash on his chest and Stain immediately licked the blood. Izuku felt his body go stiff and fell to arms and knees.

Stain wiped the blood from his face and stomped on Izuku's back "Yes I can... you act all tough and mighty... but you are one of the biggest hypocrites in this society..." He stabbed his sword on Izuku's shoulder making him hiss. "I'll make a favour to everyone with taking you out."

"GrrrrAAAAAARGH!" Izuku screamed, and with will power alone, he jumped to his feet making Stain lose his composure.

"Fist of Flowing Water..." Izuku said getting in pose, a glint in his eyes, while Stain still doesn't get back on his two feet "Rock Crusher!" He punched Stain on the face so hard sending him to the street and crushed to a car.

The alarm of the car went off and Izuku fell to his knees. He barely managed to stand up and walk away slowly. The adrenaline went off and the pain entered. He looked back and saw Stain unconscious body as police started to arrive. He looked down at Tensei unconscious body before limping away, while holding his chest and back.

*Hours Later, Hospital*

"Brother, who did this to you?" Tenya Iida asked to his brother who was just regaining consciences.

"A kid around your age... green hair, green eyes... and his name was Izuku... at least that was what Stain called him..."

Tenya nodded as he balled his hands into fists... "I'll avenge you..."

"I swear."
