Protogen is a half-robotic antromorphic latex creature that does not seem to resemble any specific animal. Their build is similar-ish to a human, and their entire body is covered by white fur. Their face is a large visor that extends outwards and displays their face entirely digitally, except for the ears which seem to be triangular and pointing backwards. They have a medium sized white tail on their back. Their personality is slightly goofy, but aggressive towards humans.
