These concepts are fan designs for a game I loved as a child called Spectrobes Origins. It had captured me with it's unique take on gameplay, creature obtainment, and especially the creatures themselves. It's original publishing studio, Disney Interactive Studios, was closed in 2016, and I don't think there's much hope the series will return.
Here, I have challenged myself to make a fan-made creature and it's evolution line. I used concepts of creatures from the games and it's style to construct what I think would be a good fit for the game. I used themes of electricity and metals, and took inspiration from certain species of snakes that go through ontogenetic color change, such as emerald tree boas.
