We all love skins. They look nice and set us apart from other players who play with that basic, free, look. It's almost as though they're running around with naked champions out there if they don't have a skin.
One thing Riot has done really well is to tell stories of different worlds with some of their skin lines. They create alternate realities in which our champions roam around and live which are different from Runeterra. Some champions are part of a Korean pop group, others might gain the powers of a dragon. Skins let our imagination run wild and envision Champions we love live completely different lives.
So here we have it, some of our favorite lore behind specific skin lines!
