Adrien ran to the locker room as fast as he could. Once there, he cautiously looked around to make sure nobody else was there.

Seeing that the coast was clear, he held up a slice of camembert. A dark shape shot out of his satchel and immediately latched onto it.

Plagg swallowed almost the whole thing in one bite, then he became aware of Adrien watching him with a smirk. He groaned,
"Oh... I hate transforming!"
Adrien just laughed in response and cried out,
"Plagg... claws out!" Then he transformed into Chat Noir before bounding out of the locker room to find the Akumatised victim.

Marinette rushed to the girls bathroom, and locked herself into a stall. She shook slightly and Tikki twirled out of her bag, looking up at her holder with concern.
"That was a close one, are you okay Marinette?"

She responded with a faint smile and answered
"Yes, I'm fine Tikki. We need to transform before he does any more damage".

Marinette stood up and cried
"Tikki, Spots on! Ha!"
At once she transformed into Ladybug and swung out of the girls bathroom, heading straight to the Courtyard where she could hear Cleanser's voice and the sound of general panic.

(LOL. Don't even ask... I know these drawings are bad but I wanted to be more "original" and draw my own stuff .
Also yes. I am aware of the Arms! I traced both these pics but the arms just... I don't even know man, they just don't like me)
