Kip. 28: The Countdown to Battle Begins! Enter, the Ginyu Force!

28

Krillin takes Gohan to see the Grand Elder to have his inner power released. However, Vegeta senses them while they are flying toward the tower, and confronts them. Nail informs the trio of a powerful evil force approaching the planet. Vegeta knows it is the Ginyu Force, Frieza's five most elite henchmen. Reluctantly, Gohan and Krillin agree to ally with Vegeta to use the Dragon Balls to make Vegeta immortal so that he can defeat the Ginyu Force, and Frieza, more easily. Krillin, Gohan, and Vegeta rush to retrieve the Dragon Ball which Gohan had left with Bulma (who wonders why Vegeta stole the Dragon Ball) and meanwhile, the Ginyu Force lands on the planet and meets up with Frieza. Goku completes his training at 100-times Earth's gravity on the way to Namek and discovers his results are much more impressive than he anticipated. (Source: Wikipedia)
