Guldo

Guldo is the smallest and least powerful member of the team physically. Though clearly the weakest member of the group, Gurd possesses some psychic abilities, including being able to stop time (for as long as he can hold his breath) and telekinesis.

[Spoiler] He fights Gohan and Kuririn, and nearly kills them before being decapitated then blown up by Vegeta. In an anime filler, he fought Chaiozu but was quickly defeated, before later making cameos in other fillers in a non-speaking role. [/Spoiler]
