I don't think I would be too far off base to say that most furries, when asked the "what superpower" question, would take shapeshifting. That would also be my answer.
But today I was thinking maybe I should expand that. The ability to change any willing person into a shape of their choosing.
I've seen pictures of people doing incredible work with animal makeup, and how happy it makes me to see someone else look how they want to makes me want to be able to do that too.
It would mean a lot of work at conventions but to see everybody being their best selves without needing to risk overheating or their $4000 fursuit getting lost at the airport sounds pretty cool to me
