In Keroro Gunso, Robobo (ロボボ) is a member of the Shurara Corps.

Robobo was introduced as

Mechanical Robobo (機械仕掛けのロボボ Kikaijikake no Robobo) .


Robobo was programmed to steal the Keron Star from Keroro. Robobo turned everyone into an electrical appliance to make them helpless but Dororo came in and defeated him, but came back bigger so the platoon had to use the Grand Keron to defeat him, but then got destroyed by Dororo again before he could accomplish his mission. At the end of the episode, despite Dororo's accomplishment, the platoon doesn't seem to find and forgot about him again, leaving him to cry alone again, but he wasn't forgotten by the Narrator, however.


Robobo is a robot, built out mechanical parts protected by a Keronian-shaped covering of grey metal. He has square-shaped glass eyes. His symbol is a white circle with a smaller black circle inside it. He wears a skull cap with headphones. His hands and feet resemble magnets. His larger form has two drills instead of magnets for hands.

How he appears in the Anime


Robobo has the power to fuse an entire city population with a nearby mechanical object. Although this can be used against him, as shown when momoka was transformed into a tank, and this ability will instantly wear off if he is destroyed. His hands can be used as magnets. His eyes can process information and locate people. He has built-in weapons and can summon a robo. Robobo also can fly using his built-in jets. Also, when he was defeated, he would turn into a much larger version of him. He can scan people to learn info about them and see weaknesses.
