"This is the first time anyone has been stupid enough to make this big a fool out of me. I did not expect such a conclusion."
"YOU'RE GOING TO PAY FOR THIS, YOU INSIGNIFICANT WORMS!! I WILL KILL EACH OF YOU AN INCH AT A TIME!"
To the terror of our heroes, Boss Freeza has finally made his appearance. The Dragon Balls are no longer operational. All of his men are dead (or a frog). And Freeza is exploding with rage. But unlike Kuririn, Gohan, and Dende, Vegeta is not afraid of Freeza. Surprised, his former boss offers to remind the Saiyan Prince how truly terrible he can be.
Elsewhere, Piccolo speeds toward the battlefield.
He is distracted by a faint, flickering ki. Nail's ki.
Nail is happy that the Earthlings got their wish, and appears to be endlessly amused by Piccolo's un-Namekian-like demeanor. (Impatient, proud, abrasive.) If only he had come to Planet Namek as a whole Namekian, he could have defeated Freeza. Piccolo knows what he's getting at; This Namekian knows about Kami. But there's no point in arguing it, says Piccolo. He'll never reunite with Kami.
So Nail asks Piccolo to unite with him.
At the end of his life, Nail can offer to merge his own strength into Piccolo's being. His individuality, Nail promises, will not be compromised. But he will gain several times the strength he has now. Nail is the last Warrior-type of Planet Namek, and he offers his power and experience to Piccolo.
"Be sure... you kill... Freeza."
"Hmph! You don't need to tell me. If I can, I'll do it for my own sake."
In that moment, Piccolo becomes the last Namekian warrior.
And he feels better than ever.
(HE FEELS GREAT. YES! YES! HE CAN DO THIIIIIIIIIIS.)
Despite his frightening Battle Power, Freeza is not dominating the battle field as he might have guessed. Vegeta thinks he knows why; Firstly, Kuririn and Gohan's powers continues to grow, especially Gohan's - Vegeta figures he is sitting on a well of strength that even he doesn't comprehend. Secondly, Vegeta proudly announces that he is well on his way to achieving that which Freeza fears most of all. He is becoming a Super Saiyan. And thirdly, Vegeta knows that Freeza is hiding his true power. Like Zarbon, Freeza has the power to transform, and increase his strength. Freeza is impressed. He reminds Vegeta that not even his father, the King of the Saiyans, was strong enough to get him to transform.
But if it's a transformation Vegeta wants...
... a transformation, he shall have.
