The Betrayed Chronon Shifter

Part 5

"It's not your Quirk they're surprised at" Aizawa said gruffly. "I played the comms over the speaker and everyone's surprised at how efficient you were"

"But... I was a sniper... All I did was relay locations and cover fire. It's not that special"

Vlad King nodded with my assessment

"Not- not that special? Midoriya you picked us apart! And you sit my ankle from wherever the hell you were! My ankle! Moving at high speed!" Monoma protested, ignoring his bruised ego. "My team should've won! We had two people more than you and three unknown Quirks!"

"I knew them, I watched the Sports Festival when I got home and analysed every Quirk I saw"

"That's not normal though Midoriya. Nobody analyses Quirks like you do" Iida said, chopping his arms. "It's something only you do, not even Quirk Doctors do it"

I frown. "Well that's just stupid, how do you properly inform someone on what they shouldn't do to avoid hurting others if you don't know what they could do? I doubt they use a machine for each test that tells them what the Quirk is so someone must be analysing the blood and analysing it"

"Midoriya. That's exactly what they do. They put blood in a machine that scans the Quirk Gene and maps out what that Quirk can do" Aizawa said.

"Huh? Wait..." I turn back to the classes. "You're limiting yourselves to what your Quirk Doctors got from a machine? We aren't machines. Humans adapt, our DNA evolves, changes as we grow older, so of course our Quirk would be different when we became older. Like Yaoyorozu, how big were the things you could make as a child?"

She started at my sudden call.

"Roughly the size of... A can of deodorant? Then I'd feel hungry"

"How did it look when you made things?"

"Why are you asking?" She asked.

"Just... Humor me"

"My skin glowed like it always does, white"

"Yaoyorozu your skin shines rainbow. You can made two fifty kilogram iron cannons and still make ammunition. Your Quirk coverts the air and energies around you into the internals of whatever you make, but your fat constructs the shell. For small things your skin glows white, like a button or a string, but for the most part you build stuff with the surrounding air" I explain.

She looked stunned and froze in position.

Then she fainted onto Jirou's shoulder, who didn't look all that put out by it.

"Quirks change as you grow older, your DNA different. Monoma could use Mirio's Quirk for example, if he had a sample from when Mirio was a second year, but if he used a sample from when he was a kid he wouldn't have Mirio's instinctual control like he does with everyone else due to Quirk Memory, like genetic or muscle memory. Which is why he can only hold three Quirks, the more he uses a Quirk the more it's Quirk Memory would be remembered and he could use it longer and longer... Seriously, none of you think about why you can't do more? Tetsutetsu, you use the iron in your body. Ever thought of injecting yourself with different trace amounts of non harmful metals?"

Everyone seemed shaken by my words.

"What? It's just a bit of common sense. Eyes and hair change colour as your DNA shifts due to age, wrinkles form and joints begin to creak, all DNA shifts. Why wouldn't the Quirk Factor be inadvertently or actively changed by it too? Depending on it's type, Tsu for example has an Age Based Mutation Progression Quirk. Born as a tadpole, grew up to lose her tail and gain her frog body"

Tsu ribbited and nodded, not even looking phased by my words so far. Much of the class looked faint but better than 1-B who were near fainting.

"Geeze, I'll give you lot my Quirk analysis and let you work off it. Aizawa can you close your eyes? I got a test for you"
