Chat noir superhero of Paris with ladybug (ladybug is marinette he doesn't know that because they can't tell eachother their idenities for safety reasons) and marinette and chat noir aren't even  that close but they do know eachother. Taller than marinette (marinette is very short) , older than her by 2 years she's 14 he's 16, stronger than her obviously (she's actually really weak but because as ladybug she has powers as ladybug she's strong) marinette gets easily scared while chat noir isn't.
