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. As his civilian identity, he was dating Marinette Dupain-Cheng. After a long while, he learned that the girl he was dating was the girl he fought with when he was Cat Noir. Marinette was Ladybug so he revealed he was Cat Noir. They met each other's kwamis, Tikki who was Marinette's and Plagg who was Adrien's. They started going out on dates together even if people watch them out in public together.

At school, as Marinette and Adrien. They got assigned a big project together. They would work together, as their civilian identites and as Ladybug and Cat Noir. They were always complaining about the project and always had minimal time since as Superheroes, they had to save Paris constantly and not much time to work on the project for school. One day, Cat Noir said..

"What if we told Ms. Bustier that we're Ladybug and Cat Noir? Would she give us more time on the project?"

Ladybug shook her head. Little did she not know, Adrien/Cat Noir planned to tell the teacher the next day. That's what happened, Adrien dragged his girlfriend Marinette with him to tell Ms. Bustier, their teacher about extended time since they're superheroes. Adrien held Marinette's hand, looking at the teacher to speak.
