|List of all creatures|
The Gaw-Rak-Rak is dinosaur-like beast with two heads. Almost as big as a Brontosaurus and with a similar anatomy, the Gaw-Rak-Rak lives deep in the waters of the River of Despair but is quite capable of walking on land as well. Each of its serpentine-like head has rows of sharp teeth as well as a forked tongue and its powerful claws and massive tail make it a force to be reckoned with.
The first time that Lion-O encounters the behemoth is when he is on his way to see the Netherwitch. As he is making his way to the Pit of the Netherwitch by crossing the Bridge of Slime, the beast emerges from the murky waters of the river and lunges at Lion-O with both its heads. However, Lion-O's superb feline agility allows him to avoid the Gaw-Rak-Rak and the monster finally gives up and sinks back into the River of Despair.
The Lord of the ThunderCats has a second run in with the Gaw-Rak-Rak during one of his Anointment Trials. While on his path to beat Cheetara, Lion-O ends up in the River of Despair and is pulled into the Whirlpool of Infinity. When he surfaces from it, he is chased by the Gaw-Rak-Rak who continues following Lion-O on land as well. After much effort, Lion-O succeeds in outrunning the monster by diving into the River of Despair from a high cliff.
