More older artwork, this one of a Sonic fancharacter, Drillbit the Mole.
Originally an archaeologist, Drillbit (or Bit for short) is a reluctant combatant at best, typically using her enormous claws for digging tunnels or hollowing out the underground bases the Freedom Fighters seem to prefer. Actually, they usually try to keep her from the front lines; between her lightblindness and severe nearsightedness, she's just as likely to impale them as Robotnik's troops.
I originally made her for a "Sonic Heroes"-esque parody trio (collectively known as "Team Rejex") as the Power component, although I'm not sure what her area attack could be. I also originally gave her an Aussie accent, but a British one seems more appropriate (especially since I don't know enough about the Downunda Freedom Fighters).
