On the spot character creation

Welll this was actually supper hard to draw. In this roleplay i made i had to come up with some reason for these protection domes appearing... I didnt want to say the shapeshifter because... Well that would be making him op...(hes also a killer and gives cats powers) so this is his successor... A black munchkin Sphynx... With the squitten mutation... Hes supose to be the size of a kitten too but longer... He looks like he has gills. Anyone reading my desctrition i dare you to try drawing this character.
