Dragon Ball Kai Episode 40 English Dubbed Episode Title:Frieza's Final Transformation! The Ultimate Nightmare Begins!.Episode Description:Frieza dodges Gohan's attack but quickly finds himself on the receiving end once again - the young half Saiyan unleashes a massive ki blast that even the tyrant himself has immense difficulty deflecting. Frieza then decides to transform to his fourth form - the final and most powerful, and also his true form. Vegeta's plan to defeat Frieza involves having himself mortally wounded and then being healed by Dende - which the Saiyan prince achieves by having Krillin shoot a ki blast through his chest. Vegeta has concluded that each time a Saiyan is badly injured, his power level will increase substantially after he is healed, and he predicts that recovering from another fatal attack should make him powerful enough to defeat Frieza. Vegeta lowers his defenses to allow Krillin's attack to succeed, and Krillin proceeds to deliver a devastating blow to Vegeta. What nobody realizes is that Dende has no interest in healing Vegeta; Dende runs from Vegeta and instead heals Piccolo, who eventually convinces him to heal Vegeta as well. Frieza eventually reaches his final form, and immediately kills Dende with his Death Beam technique - having witnessed his healing abilities while transforming; Frieza has realized that this may be the key to defeating the others. Krillin, Gohan, and Piccolo go on the attack but the tyrant easily dodges every single attack they throw his way. Vegeta watches them fight from a hill, preparing to charge up to his newfound power level as Gohan finds himself on a direct collision course with another one of Frieza's blasts.
