Rasin and Lakasei are a pair of alien brothers that serve as henchmen for Turles and are villains from the Dragon Ball Z movie, The Tree of Might.
Next to nothing is known about Rasin and Lakasei's past, except for the fact that they were recruited by Turles at some point.
After deciding Earth was able to sustain the Tree of Life, Rasin and Lakasei, along with their cohorts, Amond, Daizu, and Cacao, accompanied Turles to the planet, so as to plant the tree. The duo, along with the others, fought against the Z Fighters after they attempted to put an end to Turles's plans and won rather easily. They later took on Son Goku, only to be meet their end after he used his Kaio-ken technique.
