If we end up adding more regional forms, we were discussing adding Zubat (as an anon already posted.) If we add it, it would be Electric/Flying (as per discord) and to fit in with the regional lore. We will either have Mantine be Electric/Flying as well (as was decided early on) or we'll change it to the design in pic related, a prospective Poison/Ground.
