Krutch was a gladiator resembling a spider.
In 22 BBY, Krutch was a gladiator who took part in the melee within the Cauldron. He utilized all six of his limbs to manage various armaments and implements, including a net and assorted knives. In the course of the battle, he managed to slay the reptilian Crockagor. Ultimately, though, Kulltu Kutta overcame him.
A prominent error occurs in the episode where Krutch appears to die on two separate occasions: initially at the hands of Kulltu Kutta, and subsequently by Asajj Ventress when she dislodges stalactites from the roof to obliterate a number of gladiators.
