Giru

Giru originally known as T2006 or DB4649T2006RS, is a Machine Mutant that accompanies Goku, Pan, and Trunks on their quest to find the Black Star Dragon Balls. He is "best friends" with Pan; however, he is frequently the recipient of a lot of abuse at the hands of Pan, which makes him somewhat fearful of her. Giru is shown being rather cowardly, cowering at immediate sign of danger. Although Giru is cowardly he does show some sigh of bravery, when he saved Pan from a giant sandworm on planet Rudeeze and when he attacked Baby when he attempted to hurt Trunks. Giru also a habit of repeating name, especially when he's in fear. When they reach planet M-2 Giru "betrays" the group. Later on, it was shown that he was only just pretending, as ordered by Trunks proving himself to be a loyal companion.
