Une force insurmontable

As Frieza begins to transform to the Z Fighters' amazement, the alien tyrant grows two inches and destroys his battle armor in the process, revealing a white-colored bodily armor with three more purple areas on which Vegeta mockingly describes as a "transformation". Before continuing to change, Frieza asks Vegeta to surrender and obey him once again, but the Saiyan Prince refuses. Frieza then decides to tell Vegeta that it was actually he who destroyed planet Vegeta long ago, wiping out the Saiyan race including his father King Vegeta when the prince was a young boy. Vegeta claims that he knew all along, which was why he hated Frieza so much. Frieza also reveals another secret that Vegeta's father had never experienced: he can transform. Eager to finally destroy Vegeta and his allies, Frieza transforms into a hideous giant and explains that in his new form, his power level is over one million. After destroying the island with an explosion of energy, Frieza locks on to Krillin, his first target, and impales him on his left horn, horrifying Dende, Gohan, and even Vegeta. (Source: Wikipedia)
