Batty resembles a purple bat with red wings, two large fangs, and small round feet.
Batty flies around in one place or hangs on the ceiling until Kirby comes near, then it chases after him, trying to crash into him. While it flies, it seems to move in an erratic zigzag pattern. If Kirby flies away for too long, Batty will give up chase and return to its original spot.
- Batty having shut eyes may be a reference to the common belief of bats having poor eyesight.
