SBR Chapter 31

Scary Monsters (4) (スケアリー モンスターズ その④), originally in the UJ release, is the seven hundred eighty-third chapter of the JoJo's Bizarre Adventure manga. It is also the thirty-first chapter of Steel Ball Run.

Summary
The guardian of the Eyes whispers to Diego the word "Turbo". Realizing that Diego is told the location of the next Corpse Part, Johnny shoot at Diego, but the now fully controlled Gyro defends him from Johnny's nails with the Steel Balls. Dr. Ferdinand, the true master of the dinosaurs and agent of the government, makes his apparition. The geologist reveals notably that his employer is the government, that the Corpse is 1900 years old, and that it will bring about an eternal kingdom, to Johnny's denial, who claims that no one could have such influence.

Johnny decides to temporarily abandon his Left Arm and transform into a raptor, using his tail to leap toward Diego and whip the Eyes toward Gyro. Johnny is then incapacitated but Gyro absorbs the Right Eye. He is cured of the transformation and gains a scanning ability which enhance his sight to extraordinary levels. One Steel Ball severely hurts Dr. Ferdinand, who hides among the raptors. Gyro is however able to decrypt the vibrations his ball causes and is able to tell in which dinosaur the geologist hides. Johnny shoots him and Ferdinand's power is cancelled. Unfortunately for him, he finds himself among cougars who devour him. The duo also see Diego depart with the Left Eye, having somehow kept his ability to transform into a dinosaur. They now know that Diego will also chase after the Corpse Parts, and resume their race.
