Adrien is a boy living under his father, Gabriel Agreste and with his father's assistant, Natalie. Adrien kept a secret that he was a superhero saving the word. The famous Cat Noir.

Adrien never acted like himself when he transformed into Cat Noir. As Cat noir, he kept his blond hair, green eyes below a black eye mask which covers his eyes but kept that he could see, outfit in a tight black suit, long black belt as a tail, cat bell, black cat ears and the power of cataclysm which causes immense destruction. He possibly got affects with his kwami's persona, Plagg. He liked a girl named Marinette Dupain-Cheng, daughter of a baker known for the great pasteries. He had no idea Marinette was Ladybug who fought alongside him to face supervillians. They were oblivious to each other's identities but never allowed to tell each other.

Whenever he would want to visit Marinette, He transforms into Cat Noir and goes off to Marinette's rooftop which had a door to go into her bedroom from above, landing in her bed.

This one day, it was raining really hard but Adrien wanted to visit Marinette so he did what he always. He transforms into Cat Noir and goes off to Marinette's house. He bumped in then Marinette dragged him inside, onto her bed with her. She was dressed in her pajamas. Cat Noir smirked at Marinette as per usual when he got a towel shoved in his face. He knew Marinette always worried about him especially when he visits in heavy rain. He purred softly when he felt Marinette drying him off. He always liked their closeness even if they didn't have romantic feelings for each other. He chuckled and purred at her gentleness. "...."
