I'd like to note that this is opposites, so I changed up how Nathan and everyone else gets akumatised so I hope you still enjoy :3 anyways here we go....

' Listen to me chat blanc' Adrien heard in his head and he stood from his chair.

"May I use the bathroom?" He asked the teacher.

She gave a small nod then continued the lesson as Adrien exited the classroom and dashed down the stairs to the restrooms and hiding in a stall. His face lit up with a pink as the well known Hawkmoth spoke.

"Its time Chat someone has been disturbed, now help them find our new miraculous!"

"Of course sir..." He smirks. "Plagg claws out!"

Plagg flies out of his jacket yelping not wanting to transform.  Adrien flies his hand across his face making his black mask appear then swiped it over his head making his cat ears appear. His skin tight suit wraps around his body and lastly a belt shaped like a tail appears on his lower back and he is full transform as Chat Noir.

" One last touch." He hears Hawk moth chant in his mind as an Akuma approaches his miraculous and lands on it softly. Then he is enveloped in darkness turning his costume pure white and eyes a golden yellow.

He shoots out of the bathroom and searches for his victim. He looks around the school quietly until he finds a redheaded boy huddling in a corner of the gym tears drenching his face.

"Why can't they understand my art?" He whispers quietly as Chat Blanc approaches.

"I know how you feel Nathaniel." Chat says slyly kneeling next to Nathan. Nathaniel freezes in terror as Chat continues to speak. "Chloe should have never made fun of your art like that, they wont understand, unless you prove to them that you are the best. Show them your power Evillustrator, teach them the power of art."

Chat holds out his suited hand with an evil smile and Nathaniel, hesitantly takes it as the pink image appears on his face and Hawk moth discusses the agreement and then Nathen is transformed.

Nathans skin is tinted purple an his hair brushes back with purple tips appearing and a black beret now on his head, a black butterfly mask appears on his face, along with a black and white stripped suit, with black pants the turn to red on his lower legs, then an emblem appears on his chest consisting of  red blue and yellow circles, and finally a tablet his attached to his right forearm and his akumatised silver pen in his left.

"They will pay..." The Evillustrator bellows.

"Yes they will, and I'll make sure to accompany you." Chat replies as they shoot off to create destruction to the school and the students inside.  

...

The class was silent as they worked hard on their assignments typing on their tablets when there's a sudden burst through the wall with an evil laugh as the Evillustrator draws on his electronic creating a gigantic monster and giving a wild smirk.  

The creature screeched loudly black ooze escaping from its mouth as it swiped at Chloe, barely missing her as she complains how it almost wrinkled her jacket.

"Oh no..." Marinette mumbled as she rose from her seat and pretended to run with the others until she reached the girls locker room and hid behind a corner.

"We have to do something!" Tikki shouted worriedly flying from Marinette's purse.

"Your right, Tikki Spots on!"

...

"I'd stay where you are if I were you."  Chat Blanc growled his staff blocking students from leaving a small corner.

"Now- its time I show you my true art!" Evillustrator yelled drawing something monstrous, but as he is about to finish the tablet is kicked out of his hands.

"Excuse me!" A feminine voice called. " I don't think trying to destroy your classmates isn't a positive attitude."
