You wanna know how Miraculous Ladybug came to be?

At a World Meeting...

France: Hey, Korea...

S. Korea: Hmm?

France: I think you'd look pretty as a girl.

S. Korea: *very much elated* Really?!

France: Yeah, probably.

S. Korea: Cool! How about if I looked like a superhero too!

France: ... What.

S. Korea: Yeah! A female superhero that came from Korea! That'd be amazing!

... And the rest is history.
