Where to begin? Well, to be honest, I have a character I created (originally inspired by a show) that has powers. Except, her powers are a bit different from "normal" perspective. You see, my original character, named Kielo, superpower centers around her wings. When I designed her, I was really inspired by the idea of an angel struggling to maintain the concept of "good". But that's another matter to discuss at a later time. Anyways, her wings. You see, although her wings appear angelic in nature, they're not just two extra limbs on her back. She actually has the ability to control the genetic makeup of her wings, which also includes her ability to change the size of them. In a sense, she can have a larger wing span to support her weight, or cute small "cupid" wings. She can even shrink them down to where she can hide them completely (they appear as a slight hump to her back). Along with this ability to change their size, she can change what the feathers are made of. For example, instead of soft feathers, she can harden them to use her wings as a shield, or sharpen them to use them as throwing daggers or such. She of course, does not have all these abilities at once, and learns how to control them in time. So here's my thing, when talking to a friend about it, they were so adamant to point out that the idea and concept is "illogical and the workings of a child's thought process". Because apparently it makes no sense that she can control the ability in her wings and not the rest of her body. In fact, to them, her entire power doesn't make any sense at all. I guess what I'm asking, is as writers (or fans of the genre) would it make any sense for this power to exist? Or am I going too far out on a limb with my concept?
