I'm just gonna go with shape shifting because... reasons...
Anyway I don't know I used to be a thief and it sounds really useful for stealing, right now I'm just not comfortable looking like I do all the time, don't get me wrong I like it and would still look like this most of the time but you know it'd be nice to go for a walk every now and again without everyone looking at me like I'm a freak, I'd say it's my fault for dressing like I do but even before I started wearing my long coat with my red scarf that makes me look like a super hero everyone looked at me like I was a freak, I remember this time I went to an arcade because I felt like playing games and everyone was watching like they were scared, it was really uncomfortable and I had to leave without playing anything because I was clearly bothering everyone with my presence and everyone was bugging me with their judgmental stare.
I mean it'd just be nice, because I legitimately like the way I am but it'd be nice to not stand out for once, besides I could go into places without looking suspicious, into any place, I love exploring and that would be super cool.
