Dragon Ball Kai

After impaling Krillin, Frieza slings him into the water. Gohan rushes to rescue his friend, but his path is blocked by the tyrant. Gohan's rage from seeing a friend in pain gets the better of him, and he immediately starts attacking Frieza and overpowers him, much to Vegeta's surprise; Vegeta had never seen how strong emotion dramatically increases Gohan's power levels. As Gohan knocks Frieza out of the air and attacks him with energy blasts, Dende saves Krillin from drowning and heals him - this was one of his hidden powers that the Grand Elder had unlocked. Frieza charges towards Gohan to get his revenge, only to be blasted in the back by Vegeta - which, to the Saiyan prince's disappointment, does absolutely nothing. Frieza begins thrashing Gohan, but he is rescued by the healed Krillin, who cuts off Frieza's tail and distracts the tyrant with numerous attacks and escapades - buying just enough time for Dende to heal Gohan. It becomes clear that Frieza outclasses them all, so the three warriors begin blasting him with everything they've got. Once again, it has no effect, but as they are about to charge him in their moment of desperation, Piccolo finally arrives on the battlefield, announcing that he will be the one to win the battle.
