Kulu-Ya-Ku has a body shape similar to other raptorial Bird Wyverns, such as Velocidrome. This monster is covered in light brown scales and has a face that greatly resembles a Dodo. Though it is mostly covered in scales, it also has feathers on its head and arms.
Kulu-Ya-Ku is able to pick up small boulders and use them to protect itself from incoming attacks. It can also toss said boulders at foes from a distance.
- By using the Slinger, hunters can easily knock rocks out of the Kulu-Ya-Ku's hands.
- Hunters can also break the rock by hitting it multiple times with their weapon.
- Kulu-Ya-Ku's head and arms can be wounded.
