>>45226157I'm working one a fakemon region that has a Heliolisk with an executioner theme. The original design has something that resembles an executioner's hood already, I made the tail into something of an axe. It turned into this form after a nearby volcano erupted causing them to flee into a cave where they were locked in after the lava cooled and hardened.
