Big Gete Star robot
From Dragon Ball Wiki, the ''Dragon Ball'' encyclopedia
The Big Gete Star robot, or Guidance Robot, was a small brown servant robot that appeared in Dragon Ball Z Movie 6, Dragon Ball Z: The Return of Cooler. He escorted Son Gohan, Krillin, Yajirobe, Muten Roshi, Oolong, and a group of Namekians through the Big Gete Star in order to take their energy and use it for fuel. He insisted that he did not want to hurt them, but ironically he later said, "just want to chop you up". He, like the Cyclopian Guards, had transforming and expendable appendages that were very strong to the point where all of the present company, even Gohan or Krillin, could not pull Yajirobe free from its grasp. Once the main core of the machine planet was destroyed, the robot's singing about "chopping them up" was interrupted when he blew up.
[edit] Trivia
This robot looks very similar in function and appearance to the robot that serves as Gurumes' Robot Servant in Dragon Ball: Curse of the Blood Rubies.
