The Bas appear as small creatures, with Guldo, the only confirmed Bas, having the appearance of a green creature with four eyes. The enemies who appear to be Bas in Dragon Ball Online have skin colors that range from green to blue, and some of them have five eyes instead of four. The two presumed members who appear in Dragon Ball Z: Super Saiya Densetsu, Zella and Purin, appear as pink and yellow versions of Guldo respectively.
At some point in history, Frieza integrated members of this race into his Galactic Frieza Army. Their blood color is purple as seen on Guldo's decapitated body. Thanks to his special psychic powers, Guldo was chosen by to join the elite Ginyu Force. A tall Bas appears as one of Frieza's 1,000 soldiers in the Resurrection ‘F’ manga. Other members of the Galactic Frieza Army and Time Breakers who look similar to Guldo appear as enemies in the computer game Dragon Ball Online.
