This is my take on a Psychic/Bug line based off of mantises. The main inspiration behind the designs will be Enigmantis from Pokémon Sage. If you guys think it's too close to the source material, I will change it to something less blatant.

These Fakemon are functionally blind but uses the gem (and crystal ball for the evolved form) to not only see, but also allow it to predict the future.
