Hmm, well as obvious as it is the phobie of my choice would be Cat related. It’ll represent the fear of cats, it’ll also be as pretty as they come. The face would be flawless with pretty big eyes and so on. I’d say the special skill would be the cat opening up its rib cage or even its mouth and shooting other multiple tiny cats that would scratch and go crazy on the enemy. Azrael is what I’d call it.
