The akuma had been defeated and Ladybug, who Cosette knew was also Marinette. It settled in a few hours after the knowledge had come to her. Hiding in an alleyway, Cosette grabbed Marinette's wrist after school.
"Cosette?" Marinette said. "What did-" Cosette cut her off.
"Marinette! I saw you transform!" Cosette said. Marinette bobbed her head, curious, but clearly worried.
"You what?"
"You're Ladybug! I was going to the bathroom and I saw you transform with your little bug like thing that flew into your earrings and you became LADYBUG!" Marinette knew there was no lie she could come up with to convince Cosette she was wrong. She had seen Marinette's kwami, and her whole transformation.
"Yes, I am Ladybug," Marinette sighed.
"YES!" Cosette did a fist pump in the air.
"You can't tell anyone!" Marinette said.
"I won't. I promise, and I'm here for you!" Cosette said. "B-ut, while you're at it, can I have a miraculous? Pretty please? I may really really really want one!" Cosette had a big smile plastered on her face.
"Fine, if you keep quiet," Marinette sighed. "Meet me here tomorrow after school."
"Yes!" Cosette said. She skipped home, and the next day was the happiest girl in the room. After school, yet again Cosette pulled Marinette into an alleyway.
"Cosette Johnson, I present you with the dog miraculous," Marinette said, holding out a box. "You will use it for the greater good." Cosette nodded and grabbed the box revealing a collar with bit of orange on it. Suddenly, a bug-like thing that looked like a dog flew out.
"I'm Barkk. To transform say, 'Barkk, playtime,'" the dog-thing said.
"What are you?" Cosette asked.
"I am your kwami and when you say those words, I will be sucked into your collar, making you become a dog themed superhero," Barkk explained. "Try it!"
"Okay," Cosette said. She put the choker type necklace on and shouted, "Barkk, playtime!" A transformation took place starting with her hair turning a light pink on the tips and then a white mask coming onto her face. Her outfit turned into an orange jumper with a orange and white tail. At perfect timing, an akuma was discovered.
"What timing!" Marinette said. "Tikki, spots on!" Marinette transformed into Ladybug and smiled. "Come on, we have people to save." Ladybug winked and, using her yo-yo, flung away. Cosette's way of battle would be a white guitar.
Okay, so I got a little carried away, but I hope you liked it! So, I'm giving you a couple choices. I want to know who you want the akuma to be, and what special power you have, and it cannot be the same as any other superhero's, but just so you know, the dog miraculous is the miraculous of Happiness for what I'm doing, so choose something along those lines.
