Every member of the Wolfpack has a base picture. Even though they don't all appear in the role plays all the time. Some of the kids that are used, have already grown up, so there's not a lot of worry about finding another base pic that resembles them as they are age up, you just have to find the one you want according to the age. The guys that handle my ladies' "mates" and I have spent a decent amount of time going over base pictures. I know, sounds crazy for it to be an imaginary world and a hobby.
So, it all started with the Wolf Family... Kalvin and Jackson, Vincent and Xavier, and sister Sarah (her banner isn't made yet).
And we can't leave out their "associates"... Enigma.
