I originally thought of doing the Eeeveelutions as a Voltron sorta-thing, but instead had the idea of making them Search and Rescue bots. So here's UMB-197, a model meant for saving those stuck in deep caves and caverns.
Equipped with infra-red vision to detect heat signatures and lights for guiding the lost out. Also comes with a drill tail for getting through heavy rock, and claws for more precise digging. The radar dish helps map out the cave walls where it's too dark, and slots away in the ear to protect the small components from low ceilings. Finally, a rope and winch are installed on the back leg to pull casualties out of deep holes.
Let me know what Pokemon you might want to see a mech version of next! Probably going to do a non-eeveelution before I do another search and rescue bot, but if there's one in particular you want to see I'll throw it next on my list!
