Grunthor

Grunthors are huge T-rex like leviathans that live on the prehistoric planet of Sargasso. These huge creatures try to attack Ratchet by running up to you and head ramming you and firing deadly balls of energy at you. There souls can be collected and given to the Smuggler for Bolts and the Decrypter. If you kill all of them in the level you get a skill point.
