Cui (キュイ, Kyui; lit. "Kiwi") is an alien character and villain in Dragon Ball Z, and appears briefly in Dragon Ball GT. He is an indigo-skinned, scaly, fish-faced alien and an elite soldier who serves under Frieza in the Planet Trade Organization.
With the exception of his boots being green, he wears the common armor that most of Frieza's soldiers wear, including shoulder pads and a scouter, and he is also a rather cocky fellow who easily underestimates many of his enemies. His name is an alternate spelling of the kiwi fruit.
Only in the anime, when Gohan, Krillin and Bulma stumble into an unknown spacecraft, they find out that the inhabitant's planet was attacked by a battalion of Frieza's army, which was led by Cui. Cui singlehandedly managed to slay all in his path and the survivors of the onslaught (who were led by Zeshin), told the story of his domination. Cui was initially Vegeta's rival in the years he was working under Frieza. During the Namek Saga, Vegeta is left beaten after a fierce battle against Goku, Gohan, Krillin, and Yajirobe on planet Earth. After he recuperates on Planet Frieza 79, Cui approaches Vegeta to give him some surprising news: Frieza is already on Namek and he is searching for the Dragon Balls
alongside his henchmen, Zarbon and Dodoria. Vegeta is furious about this because he hoped to collect the Dragon Balls for his own desire to obtain immortality. Cui mocks Vegeta but this does not destroy Vegeta's confidence. In fact, Vegeta jumps into a space pod and speeds straight to Planet Namek in order to gain control of the situation himself. Cui is left yelling and screaming after Vegeta, telling him to stop. However, during this brief intermission, Cui gets the order from Frieza that he can freely eliminate Vegeta. Cui, who had waited for Frieza's approval for quite some time to eliminate his arch rival, decides to take action by boarding a space pod and following Vegeta. Once they both arrived on Namek, Cui traced Vegeta with his scouter and came face to face with him.
However, Vegeta let him in on a secret: his power level had increased substantially because of his previous defeat and he also learned how to control its output. Cui expected Vegeta's power level to be approximately the same as his (18,000), but this was a complete underestimation of his arch rival. Vegeta surprised Cui with his extremely high power rating of 24,000 and he overwhelmed him with an astounding demonstration of his aura, destroying Cui's scouter in the process, also frightening Cui. However, Cui decided to try and trick Vegeta in order to be victorious. He told Vegeta that Frieza was behind him and took the opportunity to launch an array of powerful blasts. After the dust cleared, Cui laughed and thought himself to be the victor, but was surprised shortly thereafter when Vegeta appeared behind him and told him that his speed increased as well, since he was able to dodge the blasts in a split second. At this point, Cui decided to flee the battle, tripping as he frantically and fearfully dashed upward. Vegeta, being the ruthless warrior that he is, flew right after him. He slammed Cui's stomach swiftly, cracking his armor and sending him propelling into the sky. He then smiled and mercilessly blasted Cui to smithereens in midair.
