They look like vultures with a purple coat of feathers covering their entire body, a big yellow beak and foot. The other foot, as well as the neck and half of the face is entirely robotic. They have a red eye in the mechanical part of the head, and a normal eye in the other part, which is covered by pink, bald skin. They appear again, nearly identical, in Crash Bandicoot: The Huge Adventure.
They stand on one spot floating in mid-air flapping their wings to mantain the altitude. When the player gets too close they will fly downward and move along the ground toward the player. a spin attack will make the player bounce backward, they can only be defeated by an attack from above, live a jump or a belly flop.
If the player doesn't defeat them, they will go back to their original spot and attack again if the player comes back.
In Crash Bandicoot: The Huge Adventure, their behavior is basically the same as their Crash Bandicoot 2 counterparts.
