Batman and Robin reach Riddler and Two-Face's lair on Claw Island, where they are separated. Robin encounters Two-Face and nearly kills him, but spares his life and is captured. Batman confronts the Riddler, who reveals Chase and Robin trapped in containment tubes above a deadly drop, giving Batman the chance to save only one hostage. Instead, Batman destroys the Riddler's brainwave receiver with a Batarang, overwhelming the Riddler's mind and allowing Batman to rescue Robin and Chase. Two-Face corners the trio and determines their fate with the flip of a coin, but Batman throws a handful of identical coins in the air, causing Two-Face to stumble and fall to his death.
