Just as Frieza is about to finish Piccolo off, Gohan jumps in into the fray, stopping him with a failed attack. He fires his Masenko at Frieza, but though the hideous tyrant is nearly overcome by the attack, he manages to deflect it. Realizing that Gohan is one of the few surviving Saiyans beside Vegeta, Frieza decides to transform into his final form to finish them and the others once and for all. Vegeta, however, comes up with a plan to stop him: he tells Krillin to severely injure him, insisting that when Dende heals him, he will become much more powerful. Krillin reluctantly hits Vegeta with a powerful blast, and the Saiyan falls to the ground. He stumbles over to Dende, demanding that he be healed. Dende refuses and flees from him, due to Vegeta's previous atrocities against the Namekians, which causes the Saiyan Prince to lose consciousness. As his transformation nears his completition, Frieza sees that Dende has been healing his opponents. When Gohan and Krillin asks Dende why he didn't heal Vegeta, he states that Vegeta is a heartless killer like Frieza, but Nail, in Piccolo's body, convinces him to do it, ensuring that when he and Piccolo defeat Frieza, then they will have a score to settle with the Saiyan. Frieza completes his transformation, and Dende finally heals Vegeta, who furiously kicks him away as a token of "gratitude". With everyone standing together, Frieza finally completes his transformation, shattering his third form. When the smoke clears, Frieza appeared as a small alien being, with his entire white body with purple sectors; his true form. (Source: Wikipedia)
