Cosplayer, shapeshifter, and Internet micro celebrity, what couldn't she do?

Easy. Turn into animals. And, also, talk to people, much less show her actual body to the internet.

Long ago, an event had swept over the Earth. It started quiet, but then quickly grew overnight. Children could fly, teenagers could turn invisible, adults finally felt a sense of childlike wonder as they awakened to new abilities. Overnight, over 10% of the population had awakened to superpowers, with no real explanation.

It's been years, decades since that awakening, and now, there are full cities of people with these powers. You are in one, whether as someone without one of these gifts, or as someone with one yourself.
