The Devil's Palm, Part 1 (悪魔の手のひら その① Akuma no Tenohira Sono 1), originally A Battle Between Three People (3人の闘い San Hito no Tatakai) in the WSJ release, is the seven hundred seventieth chapter of the JoJo's Bizarre Adventure manga. It is also the eighteenth chapter of Steel Ball Run.
On their way to the second water point, Johnny and Gyro are being pursued by Tim. Soon Johnny and Gyro fall under the magnetism's effect and their own metallic equipment unhorses them. Moreover, as Tim approaches, not noticing the magnetism due to already moving forward, they begin to be dragged on the ground toward the cowboy, risking implosion when they collide. The three are watched from afar by the Boom Boom Family, who decide to take a closer look as Andre agonizes on the ground. Gyro throws a Steel Ball toward the rocky formations around them, pulverizing the rock into small pebbles which, because of the rock's richness in iron, converge toward Tim and unhorse him. Tim begins to fly toward the duo but manages to rope himself to rocks. He then understands that Johnny may not be the enemy and asks what's going on.
