Gohan met C-6 in the Nemuria Ruins he had fallen into, was buried in the sand. It is quite an old model robot, but it has the thought process of humans such as compassion and thoughts of self-sacrifice. Although it entered the cave for archaeological evacuation, the ceiling collapsed during its investigation and C-6 was buried in the sand for 80 years.
C-6 tells Gohan not to interrupt his sleep, but despite his resistance, Gohan wakes him several times. Due to troubles with its sensor, it had lost its sight, but its sight was restored thanks to Gohan's repairs. As the robot looks after Gohan, it begins to open up to him. However, as soon as Gohan starts digging through the sand to allow both of them to escape the ruins, the fragile ceiling starts to crumble. He sacrifices himself by using all of his remaining battery energy to help Gohan escape the ruins.
C-6 later appears in the video game Dragon Ball Z: Attack of the Saiyans. It is revealed that he is still in the ancient ruins half a year later, but with a dead battery. Gohan promptly finds a new battery for him, but he cannot free him from the rubble atop him so he decides to leave the robot there. Gohan then meets up with Piccolo again, and leaves the robot and Nemuria Ruins.
Video game appearances
C-6 appears as a character in the story of the RPG Attack of the Saiyans, and as an item that increases Special for one minute in Dragon Ball Z: Battle of Z.
- C-6 is noted as having been buried in the Nemuria Ruins in Age 681 while also being a Capsule Corporation robot. Since Capsule Corporation was not founded until Age 712, this is either an error on the part of the writers (note the character is filler-only) or C-6 was a prototype built by Dr. Briefs sometime before he officially started his company.
