After a puzzling encounter with a pizza delivery boy, and with a little help of Dean Nederlanser’s dog, Cardigan, Robin finds himself face to face with Dr. Kirk Langstrom and his family of Man-bats.

Unsure of how to handle the creatures, Robin calls in Nightwing for a little help. The two find themselves in search of an antidote to turn the Langstoms back to “normal.” Striking out at Waynetech, Robin takes one last shot at finding some help by calling Jason Bard.
