Here is Carols “True Form” named Insanity! Novarmine and Wulf both have a version of themselves like her, Allow me to explain

basically the trio are a unnamed Virus that has the ability similar to Zombies. They are normal living creatures that when consumes of another item or being, they evolve to having that in their physical form like say Nova eats a Chicken, he either mutates wings or feathers or extra eyes. Now they have “multiple personalities” where it gets physical and mental which is triggered by something certain, as for Carol its blood and she turns into this creature shown in the picture. its temporary however so once she calms down shes back to normal.
