Protect the Dragon Balls! The Namekians' All-Out Attack!

is the twenty-first overall episode in the Dragon Ball Z Kai series. This episode first aired in Japan on August 30, 2009. Its original American airdate was June 22, 2010.
==Summary==
Goku arrives at Capsule Corporation, where Dr. Brief has prepared a spaceship for him to travel to Namek in six days, as well as train. As he takes off for Namek, Goku begins to train at 20G (20 times the normal gravity of Earth). 
Meanwhile, the Namekians begin to fight back against Frieza's men, however Zarbon proves too powerful for them to handle. Discovering that his people are being located via their scouters, Moori destroys the scouters. Filled with rage, Dodoria rushes into the fray to make the locals regret the day they ever crossed Frieza.
==Trivia==
*Dr. Brief tells Goku that he found Goku's pod in shambles. This is in reference to a deleted filler portion from Dragon Ball Z when Piccolo destroyed the pod during Gohan's training. In the manga, Dr. Brief does not mention that the pod was destroyed when he found it.
