My question for you: why is Shydog called Shydog? Is it just meant to be a random assortment of letters, does it have some other meaning, or does she somehow resemble a timid canine from some point of view?
It's a nickname assigned by some other characters that stuck. Shydog is a transmorph of Jacky, a shapeshifter (a kind of shapeshifter that only has one form, usually developed in early adult hood). When she was still developing the design, it was rare for anyone to get a good look at it because she didn't like to be seen, but the general consensus was some kind of canine. It started with calling her a shy dog.
