Chapter 4 - Repercussions

As Midoriya lay in his bed at home, he felt a searing pain in his ear. The two new quirks were still adjusting to his body and he already knew the side-effects of using them.

When he had sparred with the rest of the League, it looked professional and impossible for an amateur. Well, that was exactly right. Midoriya had practiced a few times right after they left All for One's place. The complexity of his quirks was yet to be explored but he already had a theory.

Unable to sleep, Midoriya got out of bed and turned on the lamp at his desk, flipping open a notebook with 'Hero Analysis for the Future' except now the word 'Hero' was crossed out and replaced with 'Villain'. He had kept this notebook hidden away from his mother in order to divert suspicion, but he felt that she was closer to finding out any day. He opened the notebook to where he last left off, notes on his new quirks and how to avoid the potential side-effects. He lifted his pen and wrote:

"Quirk 1: Teleportation

The likeliest explanation is that 'teleportation' is created through the movement of the body's atoms and molecules to a separate place in a split second, before reforming into the body. The blue light is likely a side-effect of partial energy released from the body in the form of light. The molecules and atoms are broken down into almost invisible parts that release energy due to the breaking down of the body itself. The light energy is also coupled with heat energy as the body has no large concept of a particular temperature while in this state, and thus the light is replicated.

The destination for teleportation must be first thought of and must be in sight. The brain must input the location into the various cells before the teleportation itself, meaning that it cannot be somewhere that cannot be seen. Visualization is also important since a lack may mean an incomplete reformation. Due to the sensitive nature of the body's workings, the quirk leaves the body to feel pain or mute functions temporarily with the reformation. This has been currently diverted into the ear, meaning I lose access to the function of hearing in the small time after the reformation. The approximate time of this 'deafness' has been identified as just over 10 seconds. This means I can either train myself to redirect this, or I'll have to heighten my other senses in order to stay alive."

He stopped writing, listening for any sound that might indicate his mother was awake. Sure enough, he heard her footsteps on the stairs. He switched off his lamp and sat in the darkness until he was sure she had gone to bed. He turned on his lamp again.

"Quirk 2: Redirection

The quirk seems to involve temporary recording and translation of opposition genes into my own, thus being replicated for a set amount of time in my body without interacting with my own strands of DNA. The ability to transcript a part of the mutant DNA that makes up quirks is yet to be explored, possibly that I need to maintain a level of physical contact in order to gain access to the oppositions cells or I'll need to wear some sort of specialized clothing that can allow that. I was lucky with Magne. There must have been some degree of miniscule particle that I made contact with and hence at access to the genome.

Redirection has been pinned to be able to be accessed for about 15 minutes but fades in effectiveness over time. The activation also invokes a situation where teleportation becomes harder to control and leaves me with a longer duration of 'deafness' that I have yet to explore."

He paused. Secretly he placed back his notebook in his hiding space hidden among dozens of other notes. "Izuku, have you not gone to bed yet?" his mother said from the other side of the door.

"I have this last assignment to finish," he said.

"Okay, don't sleep late. It's already 12:30," she said before leaving again. Midoriya turned off the light and got back into bed. He had to know how to handle these new weaknesses if he was going to use them effectively.

Author's Note:

Hi hi, this chapter was mainly an attempt to scientifically explain the quirks, as well as to identify weaknesses within the quirks that Midoriya had received from All for One. Like in the series, there are mild explanations on how the quirks were used, like how Momo turned lipids (fats) into the atoms needed to generate objects. So I attempted to make a science based explanation with my current knowledge, hopefully to make this feel a little more like Midoriya while also giving that same slight scientific feel with quirks that make them seems all the more realistic. Hope you enjoy the rest of the story!
