Unknown Enemies (フリーザの秘密兵器! 悪魔のギニュー特戦隊, Furiza no Himitsu Heiki - Akuma no Ginyu Tokusentai) is the twenty-third episode of the Namek Saga and the fifty-eighth overall episode in the uncut Dragon Ball Z series. It first aired on August 22, 1990.
Vegeta vanquishes Zarbon and gains what he believes to be the last Dragon Ball. On his way to summon the Eternal Dragon, he runs into Gohan, who, unbeknownst to Vegeta, is returning to Krillin and Bulma with the final Dragon Ball.
Meanwhile, an angered Frieza summons the Ginyu Force to help him recover the Dragon Balls and capture Vegeta. When Gohan returns with the Four-Star Dragon Ball, Krillin takes him to see the Grand Elder Guru. Frieza, who is growing impatient, calls a new evil to Planet Namek.
- In the Ocean Group dub, Vegeta refers to Bulma as "that gorgeous girl" that Krillin was with. While this is not the original dialogue, it is considered one of the first clues that is an implication of Vegeta and Bulma's eventual relationship.
