8. If Izuku seems aggravated and tired: Do not do anything to provoke.
Note: Keep Izuku happy.
Have you ever felt tension in the air? The one where it was so tense a coin dropping could set someone off? If anyone looked at Izuku they would see his eyes glow slightly with the shine of an emerald. Most people in class 1-A knew to not disturb him. A lot of people knew not to mess with him. Sir Nighteye didn't know what would happen when Lemillion, or Togata Mirio, went with the intern Deku, or Midoriya Izuku, on a routine patrol.
Now some things should be noted that nobody could really know unless told about it. Like a certain explosive teen Mirio knew Izuku well. You could even say they were brothers. In another life Mirio would probably love puzzles too.
Another thing to note was that the League of Villains had already met Overhaul. They also kept tabs on where Izuku was and spied on him so they knew what type of mood he was in. They also knew what state his body was in that day. Tired.
It was when they met the little adorable munchkin called Eri that things went horribly wrong for the mastermind of evil that was Overhaul. After all, how many people have been rewound through time and space, and been given a chance to somewhat change another person's life by imprinting their memories into someone worthy of their power? The answer... not many. How many have had to stop an evil spirit from possessing a little kid as they were forced to rewind time and space again and again? The answer...one.
Lemillion grinned as Izuku held her and gave the adorable girl to him. The only words he gave his upper class-man was "How about you make her your favorite spaghetti bro?" With a grin and a salute the blonde ran away with the girl leaving a stunned villain and a annoyed Izuku. Izuku got out his phone and called his cheery friend Uraraka. He held out his hand motioning Overhaul to be quiet. He was confused as to what was going on. "Hey Frisk. I need a little help. Can you pull some of our friends together near Sir Nighteye's Agency? Especially Goat mom and Undyne. Thanks."
"So..." Izuku brought on a little stick with a red button. "A friend of mine built this...she said something about creating a portal to an alternate dimension or something? So... I am going to use this experimental thing on you! I hope you don't die!" With that, Izuku pressed the button and tossed it to the man where the device sparked. With a wave to the man a green light showed the remnants of a shortcut Izuku used. The area warped and the fool disappeared from reality.
In another world, really a completely separate dimension, monsters were fighting. The main forces were dragons of all sizes, shapes, and colors. The other side held ground type monsters like vampire and were-wolfs. None noticed a human falling from the sky until a dragon noticed and spewed out bright white flames that burnt the man until not even ashes remained.
