Scary Monsters

A dino boi that screams USHYAAAAAA

At a later point in the race, Diego meets Gyro and Johnny again in a small village in the mountains. He appears to be friendly, but just as the two heroes think he won't harm them, he suddenly transforms into a UtahraptorW and attacks them.

It turns out that the meeting was a trap set up by the bounty hunter Dr. Ferdinand. Ferdinand's Stand power, Scary Monsters, could turn living beings into dinosaurs. He uses this ability to create dinosaur "bodyguards" in his hunt for the Corpse Parts. Even Diego was turned into one of his soldiers when he was attacked by him earlier.

Gyro manages to defeat Dr. Ferdinand by fusing with one of the Turbo eyes that Ferdinand possessed, receiving a scanning ability.

Despite Ferdinand being killed and all his dinosaur minions turning back into humans, Diego escaped with the second Turbo Eye, and retained the ability to turn into a Utahraptor at will, though he initially can't control it very well. This would later allow him to use his own variation of Scary Monsters.
