Voles are small rodents that live on Planet Earth and Mobius. Often mistaken for other small creatures like rats and mice, they often have relatively small lifespans. The voles on Mobius all seem to live in the Ocean Falls Zone, with the Ocean Falls Zone Leader and his assistant Harvey being two examples.

Since the voles in Sonic the Comic live near water, they may actually be based on European Water Voles, like one of the main characters from The Wind in the Willows.
