I designed a batch of Fakemon Eeveelutions a couple years ago and I'm still fond of the designs.

The name Boldeon is from the words Boulder and Bold. I can't remember exactly what the design is inspired by but it could have just been statues and gargoyles or it's just a self-explanatory rocky eeveelution?

If you want to share or use my design, please do credit me and link back to here.
