Mon-Ark (Mothergod`s greatest creation) and his pack of enhanced Raptors (like some of the other Bionosaurs) have the ability to speak because of their bionic implants. In the first Turok game there are two types of Bionosaur raptors: those that have the brain device on their heads and those that have robotic legs and large cannons for arms. Thunder, the Campaigner's T. rex, is also a Bionosaur.
