Zaacro is a pink, shapeshifting alien who appears in the Dragon Ball Z anime.
Sometime before the Namek Saga, Zaacro ended stuck on Fake Namek. Along with his partner Raiti, he was hoping to steal Kami's spaceship while Bulma, Krillin and Gohan were journeying to Namek and arrived on Fake Namek.
They almost succeed by disguising themselves as Namekians and leading them on a false Dragon Ball quest. After Raiti comes with Krillin, Gohan, and Bulma for the first three Dragon Balls, Zaacro goes with them for the Dragon Ball in the tornado, the one in the giant's castle, and the one in the ice cave (where he mysteriously vanishes). His true form is similar to Raiti's except his skin is dark pink and he is also taller. After Raiti and Zaacro reveal their true intentions, Krillin and Gohan easily defeat them, leaving them trapped on the Fake Namek.
