Miza, Iwaza and Kikaza are secondary antagonists of the 2019 "Galactic Patrol Prisoner Saga" (銀河パトロール囚人編) of the manga "Dragon Ball Super" (ドラゴンボール超).
The three are henchwomen for the arc's main antagonist Moro, who freed them - along with every other convict - from the Galactic Prison. In return, they scout for planets which contain treasures to plunder, as well as organic life with high energy levels for Moro to devour.
When all of Moro's surviving minions arrive on Earth, Muten Roshi takes it upon himself to go after the female criminal trio, though due to their attractiveness, he is only able to successfully fight them while blindfolded. Now cornered, the three decide to fuse together into one powerful warrior, which manages to give trouble to both Roshi and Krillin. Fortunately for the heroes, Goku manages to arrive just in time to blast the fused woman, knocking her unconscious.
