"Freeza vs. Piccolo" (ピッコロの自信 Pikkoro no Jishin, lit. "Piccolo's Self-Confidence") is the one hundred sixth chapter of Dragon Ball Z and the three hundredth overall chapter of the Dragon Ball manga.
Piccolo, having just arrived on the scene, admits that Frieza looks formidable. Vegeta remembers how easily Piccolo was killed on Earth and is upset that a wish was used to bring Piccolo back to life, calling it a waste. Piccolo tells Vegeta that it will be his turn once he is finished with Frieza. Vegeta simply laughs at this. Goku, still in the Medical Machine on Frieza's Spaceship, senses Piccolo's ki and is confused by his return.
Piccolo tells Vegeta, Gohan, and Krillin that he will handle Frieza by himself. He tells Dende to take cover, and the young Namekian wonders how Piccolo knows his name. Krillin and Vegeta think that Piccolo stands no chance, but Gohan believes that he must have a plan. Piccolo begins the battle by charging at Frieza, connecting with a blow to the face. Frieza dodges Piccolo's follow-up smash, and kicks him in the face. Piccolo kicks off of a ground formation below and headbutts Frieza in the chest. Frieza responds by hitting Piccolo with his tail.
As Piccolo falls, Frieza unleashes a large Ki Blast. However, much to Frieza's shock, Piccolo bounces the blast back at him and augments it with his own blast. The attack hits home, but Frieza survives. Vegeta, Gohan, and Krillin are shocked at what has transpired. Although still alive, Frieza is very angry and curses Piccolo.
