Giru

Giru is a Machine Mutant and the comedic companion of Goku, Pan and Trunks throughout Dragon Ball GT. Originally a Dragon Radar-devouring robot they encountered in space, Giru bonded with the group after merging with their Dragon Radar, becoming able to detect the scattered Black Star Dragon Balls. Though cowardly and self-interested at first — often blurting 'Giru, Giru!' in panic — he proves a loyal and resourceful ally, using his sensors, flight and machine abilities to aid the group across the galaxy. He represents one of the few benevolent Machine Mutants, in contrast to the villainous Dr. Myuu's creations.
