Obviously set to be released after an episode of Beware of the Batman that never aired, Beware the Batman #4 features a two version of Man-Bat long after Batman‘s unseen first meeting with scientist Kirk Langstrom and includes Barbara Gordon working with Team Batman as Oracle.
Despite building on events and relationships that neither the show nor the comic have covered, the latest issue works well enough playing on a familiar storyline of Batman and Man-Bat working together to find someone else who has been exposed to the serum and transformed into a Man-Bat (in this case the young student Barbara had been tutoring).
With the show not returning to the air in January as scheduled I have a feeling these gaps in continuity could continue which may be why DC has decided to end the comic series after issue #6. As to the fate of the cartoon, given that neither DC nor Cartoon Network have discussed it in months, one has to wonder if it will meet a similar fate. Worth a look.
