Resembling a giant Iguana, the Great Jagras is the pack leader of the Jagras and is renowned for it's voracious appetite, mercilessly assaulting even monsters higher up in the food chain (which can sometimes result in it's own demise). It uses it's tail to sweep and it's body to boldly trap prey by rolling on top of them. It balloons to unbelievable proportions after swallowing prey.
