The one in the picture has it's mask on, and there's no description of what they look like underneath. Considering it's a good idea to try to take off and/or destroy their masks (due to it making them weaker), I'm kind of surprised they didn't at least have a description. Anyway, what do you think they would look like? Since they are aberrations, I imagined something weird, like having more 2 eyes and having them spaced evenly around their face, as well as having a mouth that opens horizontally instead of vertically. They are aberrations, after all, and the rest of their body looks pretty "normal" for something that's meant to be an aberration.
