The Last Patrol! is the fourty-fourth episode of Batman: The Brave and the Bold.
Batman must save the Justice Society of America (The Golden Age Flash, Hourman, Hawkman, Wildcat, Doctor Mid-Nite, The Golden Age Green Lantern, and Dr. Fate) from Psycho Pirate.
The Doom Patrol comes out of retirement when a group of villains tries to assassinate them...or perhaps bring them together?
