Ripple Overdrive (3) (波紋疾走 その③,Hamon Ōbādoraibu Sono 3), originally The Power of the Mask That Freezes Blood (血も凍る仮面力,Chi mo Kooru Kamen Pawā) in the WSJ release, is the twenty-fifth chapter of the JoJo's Bizarre Adventure manga. It is also the twenty-fifth chapter of Phantom Blood.
Speedwagon sees Dio and remembers the death of George Joestar. He becomes enraged at Dio's past actions. Jonathan also has the image of George’s death in his mind. The young boy is completely unaware of the situation, and Jonathan asks for his name. The boy tells him that his name is Poco. Jonathan tells Poco to get on his back and hold on to his backpack straps as the trio prepares to fight a hoard of undead knights. Jonathan and Zeppeli are armed with only their knowledge of the Ripple, while Speedwagon takes up a sledgehammer to defend himself. They are able to fend off the hoard, and, eventually, Zeppeli confronts Dio, who is still observing them from atop a rock structure.
Zeppeli tries to get Dio to come down from the rock and fight him, but Dio refuses to do so. Zeppeli jumps into the air and attempts to destroy Dio with a Sunlight Yellow Overdrive, but Dio counters by freezing Zeppeli's arm. Zeppeli's arm splits open, seemingly unraveling itself, almost causing him to compromise his breathing pattern. Dio prepares to crush Zeppeli's head with a punch, but Jonathan intervenes and blocks Dio's attack.
