Class 1-A and class 1-B were standing at the opposite sides of the grounds when Mic said "hello listeners, today there is the ultimate battle against classes, the students arre gonna battle to see who is the strongest. Now, since our contestants are ready to start LET THE BATTLE BEGIN!" 

And with that it began, most of class 1-A went straight to class B wanting to fight right away, all except the deku squad, Momo, Sasuke, Tokoyami and Shoji. The group of nine had split in two groups, one was of five people while the other one had four, they were confusing everyone as they took two completely different directions.

Sasuke was in the same group as Todoroki, Momo, Deku and Shoji, he saw Momo speak into the transmitter "Iida, can you hear me?" he answered in a couple of minutes "yes, I hope you can hear me." "yes I can." she answered as Sasuke saw some guys from class B and pulled all the group behind some pile of metal.

"what was that for?" Momo almost yelled as Sasuke put a finger on his lips signalling her to shut up and even she didn't understand why she dis it all the same, now the four present were looking at Sasuke as he took out a kunai and attached a paper bomb at it, he slightly lened over to see where the students were and then lunched it.

He then hid again as a dust of smoke rose from the ground Sasuke launched himself inside it, taking out two people and then going back at his hiding spot as the smoke cleared he looked at Deku, Shoji and Todoroki nodding his head, Deku and Shoji ran to grab the two unconscious people and bring the in the cage while Todoroki froze the other three in place.

After some attempts TetsuTetsu was able to break free from the ice and headed towards him transforming into metal but before he could punch Todoroki Sasuke stood in front of him grabbing TetsuTetsu's hand and kicked him in the stomach, in a very Itachi like way, with a bit of chakra he sent TetsuTetsu flying but failed to notice how Todoroki had fallen under Shinso's mind control and Monoma touched him borrowing his quirk.

When he turned around he was surprised to be met with blanc eyes "hello Shoto, you there?" he asked waving his hand in front of his eyes "he fell under my mind control.  And you'll be the next one" Shinsou said with a strange smile on his face but Sasuke just ignored him.

In that moment Deku, Shoji and Momo arrived and looked at Todoroki "what happened to Todoroki-kun?" Deku asked "he fell under my mind control" Shoji grabbed Todoroki's body and ran away to wake him up.

Monoma then launched at them ice which they dodged in different ways, Sasuke just made a mini jump not actually putting much effort in it, Momo created a metal stick fro her palms to lift herself up while Deku jumped like Sasuke, just much higher then him.

Monoma then sent fire, the amount of it was equal at a genin's level and Sasuke just used amaterasu on it, making the normal fire disappear, he then quickly wiped away the blood coming out of his eyes.

"What just happened?" asked Momo "I don't know." answered Deku "Those black flames were the Amaterasu, they're flames as hot as the sun that burn everything they touch in a matter of minutes if not less." Sasuke explained and they could see the slight fear in the three eyes' but just ignored it since he wasn't gonna use it on them unless he really had to.

"Midorya, take care of Shinso, Sasuke take care of TetsuTetsu. I'll take care of Monoma!" Momo commanded them, even if Sasuke hated to get ordered around he didn't complain and just nodded.

Sasuke had no idea who TetsuTetsu was so he just assumed it was the guy that came running at him transforming into metal. 'he looks like he's specialised in taijutsu.' Sasuke thought as TetsuTetsu threw punches at him.

Sasuke just continued dodging them which made TetsuTetsu angry that he wasn't fighting back "you should fight back! It's not very manly of you not to! You should act more like a man and less like a child!" TetsuTetsu said and Sasuke was angry, he hated being compared to a child. So he infused his fist with a bit of chakra and punched his opponent in the stomach which sent him flying and as he hit a wall he fell unconscious from the impact.

Sasuke just looked at him and thought 'weak.' Sasuke then looked at the others still fighting, Todoroki and Shoji came back and Todoroki immediately went to help out Momo while Shoji took TetsuTetsu and left.

Sasuke was looking at the fight between the others and was seeing which one of them would be useful in a fight against Orochimaru. He came to the conclusion that all of them would be dead in less then five minutes.

His thoughts were interrupted by All Might yelling "the time has finished! And class 1-A is the winner of the fight!" Sasuke looked at the speaker and thought 'obviously, they're weak.' 

Sasuke, Deku, Momo and  Todoroki walked towards the exit and when they exited the training area they found practically everyone there.

The students of class 1-A were cheering while the students of class 1-B were sad. But Sasuke didn't care, he was too bored to care.

~~time skip~~

Sasuke was in his room, staring at the ceiling when he suddenly heard a noise from outside, he went to check. When he looked down, he saw the heroes and villains having a battle.

It was quite interesting, the heroes were sweating and having a difficult time while the villains were completely fine. Suddenly a girl, one of the villains, noticed Sasuke and waved her hand in the air excitedly, Sasuke not knowing what to do just nicely waved back smiling.

The heroes looked at where she was waving at Sasuke who was waving back the she squealed "oh my god, he's so cute and nice and hot!" The guy on his right looked at her 

"Toga, please don't fall in love with random guys you meet." The girl just glared at him and the other sighed, he was bored so he decided to joke around. He suddenly shot blue fire at Sasuke "Dabi no! You're gonna kill him! I wanna be the one to stab him to death!" She said but Dabi just shrugged "too bad, the flame's already halfway there." But what he didn't expect was his flames to vanish into thin air and black flames replacing them just to then vanish.

"What the fuck just happened?" Asked Shigaraki shocked that Dabi's flames were defeated "well, they do say to fight fire with fire." Toga joked and Aizawa took the opportunity to launch his capture weapon at them but they easily dodged it "so... You heroes wanna explain what that shit was or not?" Dabi asked

"I have no idea what Uchiha did there but it's fine as long as he ain't dead." Aizawa said looking at the teen that was making friends with a random snake that appeared out of nowhere on his balcony and what confused him is that they were actually having a conversation.

But he just ignored it and when he moved his head he was surprised to see Shigaraki about to touch him so he quickly dodged his hand. Then suddenly the door to class 1-A's dorms was slammed open and Todoroki, Deku, Bakugou and Uraraka came running towards them, after two minutes everyone except Sasuke was fighting. In the meantime Sasuke was having a conversation about how boring the fight was with the snake. But he decided to come down when he saw a portal opening and various other villains coming out of it. He sighed "I can't get one day of rest can I?" He asked Jashin. And then he started walking down the wall.

As soon as he set foot on the ground a lot of villains came towards him, he actually didn't care knowing they were weaker than him, he activated the mangekyo sharingan and the ones that came towards him passed right through him and as they hit the wall most of them were now unconscious, suddenly some other villains started moving towards him with their quirks activated he and he just repeated the whole story. Then he walked over to Todoroki was super confused.

Suddenly a blue flame came towards the two, Sasuke activated the susanoo to cover both him and Todoroki and when the flames extinguished Sasuke turned off his Susanoo and the one that shot the flames was visible and a girl was next to him. "Toga, you take care of the Todoroki kid." The guy said and the girl started whining "but Dabi, I wanna be the one to kill him!" "Don't worry, I won't kill him. He'll only die if he's weak." Then the two separated Toga went towards Todoroki and Dabi shot flames at Sasuke, the latter just activated the Susanoo and sat down knowing those flames can't get through it.

When the flames finally vanished Sasuke deactivated the Susanoo and Dabi was mad, Sasuke was standing right in the way of the flames but was completely uninjured to not talk about the fact that he was normally sitting like if nothing happened. "Hey, who are you?" Dabi asked wanting to know if he was someone from a  strong family and Sasuke just shook his head "you know, it's very rude to ask for someone's name without stating yours first."

Dabi that was now obviously irritated said "my name is Dabi, now it's your turn." Sasuke rolled his eyes "ok Dabi, my name is Sasuke, nice to meet you." Sasuke said in a cheery voice. Dabi was now confused, why would a hero in training be happy to meet him? He was a villain and one of the most dangerous one at them. When suddenly he heard a pat on his shoulder 

"so, what you doing Dabi?" It was Shigaraki, the other two looked in Aizawa's direction and he was unconscious on the ground with a lot of others pro-heroes "oh, I was dealing with this idiot hero in training." He just answered and Sasuke shook his head at the villains 

"well you know, it kinda looks like you need help there." Shigaraki and then a head popped behind the two "can I help you too?!" It was Toga

"shouldn't you be taking care of Todoroki?" She smiled and said "another villain is taking care of him." Shigaraki nodded and the three started running towards Sasuke, Dabi shot flames that he easily  dodged.

He saw several knives coming at him so he took out a kunai and blocked them, when another wave of flames came his way.

"Is he already dead?" Asked Dabi with disappointed in his voice, as they looked left and right they couldn't see him but then they heard his voice "below you." He said and as they looked down three hands stuck out of the ground and grabbed their ankles, they weren't fast enough to react so all three of them were stuck in the ground with Sasuke standing in front of them

"hey, get us out of here!" Toga said "you know we're the most wanted villains in Japan right?!" Shigaraki said "then the standards here are very low because to me it looks like your D-ranks villains." 

Shigaraki was mad he thought that they were weak but what made him even angrier was the fact that his opponent, Sasuke was clearly holding back, Shigaraki touched the ground, breaking only the one around him so to not kill his teammates. 

"do not underestimate us hero. Only 'cause you were able to catch us off guard doesn't mean you're better then us." Shigaraki said as the other two continued struggling to get out "hey Shigaraki, can you help us?" Toga asked Shigaraki then touched the ground and it broke stopping were the two were "thank you!" Toga said in a cheery voice.

"So... We gonna get serious or what?" Sasuke asked annoyed and Toga sent a bunch of knives at him, he just smirked and suddenly turned into snakes confusing the three "what is his quirk exactly?" Toga asked "I have no idea." Dabi said and suddenly a portal opened in the sky, all the heroes were terrified, 'what if there were other villains come out from there? We can't handle that many villains especially not now that many of us are on the ground.' They all thought But they were all shocked to see only one man coming out from the portal and an unconscious one at that. Sasuke turned back to his human form and as he saw who it was his eyes widened.
