Appule

Appule is one of Frieza's henchmen. He is purple with yellow spots and a long skull.

The Anime
Appule takes orders from Zarbon as well as Frieza. He was one of the henchmen that, along with Zarbon, searched Namek for villages after all their scouters had been destroyed. At some point, he returned to Frieza's spaceship where Frieza ordered him to summon the Ginyu Force. He watched over the injured Vegeta as Zarbon put him in the rejuvenation tank. However, as he was insulting Vegeta, Vegeta finished his recovery, and broke out of the rejuvenation tank, killing Appule.

Appule was later seen in Hell during the Kid Buu Saga, alongside Frieza, King Cold, Cell, the Ginyu Force, Dr. Gero, and Babidi, watching the battle between Goku and Kid Buu.

The Manga
In the manga, it is Appule (and not Orlen, an orange Frieza soldier who resembles him) who discovers the Namek village Vegeta attacked.
