between the Keronians and the Vipers, and was defeated by a technique used by Dororo. He reappears in Episode 121, where he appears as a cyborg who takes revenge on Dororo, but ends up capturing Chiroro and hides in Alien Street from the Space Police and the Keroro Platoon. To keep himself from being spotted, he disguises himself as a chef in a ramen stand. When Keroro disguises himself as Viper and captures Karara in an effort to earn money, Viper takes off his disguise and attempts to defeat the fake Viper, proving that he does have some good in him. Viper's cyborg appearance is very reminiscent of Freeza, of Dragonball Z fame, when he became Mecha Freeza. His left half has been completely demolished and replaced with mechanical parts, his left eye is green and has a yellow scope as its pupil, a black tube appears on his head and leads to the back of his head, and the buster arm he had before has now been replaced with a mechanical claw. He has a son that was taken away by his ex-wife who he taught a technique on how to make the Tokyo Tower out of cherry stems. Cool Big Brother Viper The older brother of Viper. He kidnapped the Keroro Platoon and was defeated by Dororo. He soon enlarged himself but he was scared off by a larger Keroro due to the Flash Spoon.

Viper (Former Pirate) A kind Viper that Keroro, Giroro and Zeroro met when they were young.
