so, let's go with where a super secret organization spread across the galaxy called blackhawk or something similar kidnaps a military personnel who does research on biological/technological personal body enhancement. he was betrayed by his best friend in the military who was a spy for blackhawk who was only looking for a suitable person to take on a experiment that use biomechanical nanotechnology that absorb the genetic make-up of an animal and basically justs stores it in a system thing. with that if you absorb lets say a ghost tail scorpion(cool name) you can pick and choose attributes of the scorpion to intergrade into your body or just become the scorpion. you can change up the start to where the guy doesn't remember who he is/ a guy playing a game or something else.
