WB has passed me another first look at episode 9 of Batman: The Brave and the Bold titled - "Journey to the Center of the Bat!"
Special guest stars include Dee Bradley Baker voicing dual roles as both the “Brain” and “Chemo”, and James Sie as the “Atom”. Tune in to see them both on “Journey to the Center of the Bat!” airing this Friday, January 30 on Cartoon Network at 8:00 PM.

Synopsis:
This week Batman’s life hangs in the balance when he is poisoned by Chemo, who is under the control of the evil Brain. The Atom races to the rescue with Aquaman by shrinking down and entering Batman’s bloodstream. While Aquaman and the Atom battle the infection deep inside Batman’s body, Batman struggles to end Chemo’s rampage and defeat the Brain! This week’s teaser features Elongated Man and Plastic Man teaming up to derail a bank heist and capture the criminal Baby Face.
