Batman #86

In "The Voyage of the First Batmarine!", Batman and Robin dive deep to disarm underwater explosives, only to face the danger of the bends when they can't ascend safely. Forced to improvise, they transform a regular submarine into a Bat-Marine and battle Slant Stacy’s undersea gang—until the criminal devises a dangerous plan to trap Batman beneath the waves.

In "The Joker's Winning Team!" from Batman #86 (1954), the Joker swaps out his usual henchmen for a roster of crooks with niche skills, turning his criminal empire into a high-stakes game of organized crime—where every heist is a play, and every criminal a player.

In "Batman — Indian Chief!" from Batman #86 (1954), the Dynamic Duo encounter a pair of Native American warriors who mirror their own costumes and heroic roles—known as the Man-of-the-Bats and Great Eagle. When the Man-of-the-Bats is wounded, he begs Batman and Robin to step in and confront the menacing Black Elk, who suspects the two heroes are one and the same.
