It is unclear whether he is in the anime or not, but he does bear some similarities with the yellow Cold's soldier who is on Earth with King Cold and the rebuilt Frieza.
Mei-type soldiers are enemies in Dragon Ball Z III: Ressen Jinzōningen, where they appear under three different colors: the blue Mei (メーイ), and the purple Keith (キース) who appears in Act4. Keith's name pun is from Kisu, a Japanese whiting fish. Kaiz (カイズ) also appears in the unused bestiary, a green version of Mei. His name comes Kaizu, a japanese black porgy.
- His name is a pun on the word "fish".
- He appears to be the same race as Namole, another soldier in the PTO.
