Midoriya Mood

Summary: When Izuku's angry, he's ANGRY.
Midoriya has these days, on these days he's easily irritable and will lash out. These are not a common occurrence but has happened enough times for Katsuki to learn his lesson (only happens when Izuku meets his very tipping point). And if 2 adult men in the hospital is anything to go by, Katsuki has learned Izuku is very dangerous during these days. Izuku has always been kind and always tried to find the best in people, but there is a breaking point. When he is tipped over the edge the only thing you can do is hope you don't piss him off. When you piss him off you end up in the hospital and you don't want that. The only reason he never got in trouble for beating the crap out of people is because no one would openly admit to being beat up by a useless Deku.

Midoriya had these days, he would forget whole days. After this happened people always seemed to be apprehensive to go near him or talk to him. When this first started happening (10yrs old) the bullying stopped for a bit and people seemed afraid of him but after a while the bullying started up again.

This was not Izuku's week. First he had started waking up randomly during the night for no reason causing he to be very tired it also seemed Kacchan had decided to become louder giving him a headache every lesson. Second he had been out to buy some more pencils because he needed new ones and ran into one of his old bullies that promptly insulted and laughed at him. Thirdly he had been trying to focus in class when Mineta would just start pervertedly start talking about his female classmates, he had politely asked him to stop but every lesson it happened again and again. Then when he had tried to get work done after school he always seemed to be approached by people asking for help with their homework. Lastly he kept getting mixed up in every single villain attack no matter how hard he tried he was always inevitably caught in the middle of it.

Now one morning he just woke up so angry and irritated and just wanted to punch something. Getting up he made his way towards the common room. Then he heard it, the annoying yelling of Kacchan, his patience was already wearing thin. He walked into the common room with a strained smile that said 'I'm going to kill anyone that comes near me'.

Once he makes it into the common room he sees Kacchan's back turned and that he was yelling at Denki. So he said something because he was going to kill him if he didn't shut the fuck up. "Kacchan, can you kindly shut the fuck up?"
All eyes snapped toward Izuku, disbelief written all over their faces.

"What the hell did you-!?" Kacchan turns around to be met with a glare. "oh ok" Katsuki knew those eyes all too well, and he didn't feel like taking a trip to the ER today.

"Thank you!" Izuku says releasing his glare. Izuku quickly made his way past his stunned classmates and went into the kitchen made a cup of coffee before retreating back to his room.

When Katsuki was sure he was gone he turned back to his classmates with a serious expression. "Ok, I'm going to tell you something, and you better listen because I ain't saying it twice. Understood?" The class numbly nods, very confused.

"Under no circumstances are you to piss off or annoy Deku." Bakugou stated. The classes confusion grew. "Unless you want to end up in the ER" Bakugou continued, the class now was looking at him like he was stupid.

"Are you sure were talking about the same person?" Pikachu questions. Bakugous annoyance seemed to grow.

"Ok fine don't listen to me, it's your funeral" Bakugou said with smirk before leaving to get ready for school. The class decided it would be best to forget about it and shrugged it off before going to get ready themselves.

When school starts
-incident 1 (Mineta)-

Everyone was at there desks waiting for class to start but what most of the class noticed was that Izuku wasn't there and Bakugou was oddly quiet. Everyone was chatting with the people next to them. Then the door suddenly opened revealing a very irritated looking Izuku, Izuku quickly made his way to his desk ignoring the stares from his classmates. He sat down hoping no one would annoy him but alas things never go his way. He heard the voice that he has hated for the past week, Minetas.

"Hey have you seen Mo-" Mineta began. Izuku turned around to face Mineta.

"Say one perverted thing and I'll throw you out the window," Izuku threaten. Apparently he thought he was joking.

"But Mo-" he starts again. Suddenly Izuku opens the window grabs Mineta and chucks him out the window, before calmly sitting down like nothing happened.

The class was shocked. "Holy shit dude!" Sero says trying to stifle a laugh.

"Good Morning class" Came a monotone voice grabbing everyone's attention. People quickly stopped laughing when they realised it was Aizawa Sensei.

Aizawa looked around before noticing something was different. "Where's Mineta?" He questioned sounding done. He noticed that most of the class seemed to try and hold a laugh after he asked the question.

"Ok which of you finally did it?" Aizawa Sensei asked realising karma must have finally caught up to the little bastard. Something Aizawa didn't expect was everyone to point to Midoriya who sat in his chair looking very irritated.

"Ok." And just like that the class started.

Half way through class Mineta walked in battered and bruised like he had fallen through a tree. Aizawa did not miss the way Midoriya glared at him and the way he quickly scampered to his seat.

Last class
-incident 2 (Endeavor)-

"Ok class now-" Present Mix started.

"Shotooooo!" Came a booming voice. Suddenly the door swings open to reveal the one and only fucking-Edeavwhore.

On a normal day Izuku would just ignored it.
On a normal day Izuku would be too scared to stand up to Endeavwhore.
On a normal day Izuku would be tolerant of loud noises.
But today was not a normal day
It only took one face for Izuku to loose his cool.
So when Endeavwhore walked in he slammed his palms onto the desk in pure anger abruptly standing up.

"Ok! Get the fuck out!" Izuku seethes straight in the "pro hero's" face.

"What did you just say to me!?" The "pro hero" demands.

"I don't have the fucking patience to deal with you right now! So leave!" Izuku was about to rip him to shreds if he didn't leave in the next 5 seconds.

"He's not joking!" Bakugou says from a safe distance.

"You've got to be joking! A child can't hurt me," Endeavwhore laughs in his face.

And that's all it took. Izuku lunged expertly avoiding the flames after the "pro hero" realised he was headed for him. Izuku decked him in the face while the class looked in shock. Izuku just kept dodging, kicking and punching until he was beaten and bloody on the floor.

"I'll press charges against you demon!" Endeavwhore yelled backing away from the demon spawn.

"Oh really?" A dangerous glint passed over Izuku eyes as he stared down Endeavwhore. "You're going to tell the police that you got beaten down by a 'child' as you put it? And I didn't use my quirk. So you basically got beaten down by a quirkless 'child'. Oh what would happen to your reputation? 'Number one hero gotten beaten down by a child that wasn't using his quirk'. Everyone would find out how weak you are. So go ahead press charges." Izuku gave him a sadistic smile. "Let's see how far that gets you."

After Endeavwhore left beaten, the class decided to collectively agree on one thing "don't fuckin' mess with Midoriya during the now named Midoriya Mood".

A/N I may make another part where Midoriya doesn't remember threatening Endeavor, and Endeavor tries to confront him but just gets an oblivious Izuku.
