Leaf Tailed Vesper
Blitz is part of a fictional race of Vesper bat, the Leaf Tailed Vesper, or "Dragon Tail". This was mainly due to the fact blitz loathed his short tail, and wished for something practical. The leaf tails characteristic leaf shaped fin assists in flight, to compensate for an anthropomorphic bats difficulty to control direction.
