Freeza

Frieza's fears were realized when he was defeated by Goku, who in turn had become a Super Saiyan. His character would return shortly thereafter, having survived the encounter with Goku but having been left with multiple metal prosthetics. Though accompanied to Earth by his father, Frieza is unable to avenge his loss, being killed with relative ease by a newcomer to the series, the half-Saiyan time traveler Trunks. A blood sample taken before his ultimate fate would later become a catalyst for the next arc's featured villain: Cell, a warrior genetically engineered to be perfect. After Frieza's death, he was kept imprisoned in Hell, with the Angels of Hell being the ones who were tasked with ensuring that he remained captive. During his time in Hell Frieza retained his Mecha Frieza state and was left trapped inside a cocoon. over 14 years after Frieza's demise, his two elite soldiers Sorbet and Tagoma collect all of the Dragon Balls and resurrect him, and he is revived as he was just before his death, as Mecha Frieza and in pieces. Sorbet and Tagoma collect all of the pieces of Frieza and put the organic parts in a healing chamber, Frieza's body is regenerated and he reverts himself back into his first form. Frieza believes that through four months of serious training, he will be able to reach a level of power high enough to wipe out the Saiyans in the blink of an eye. Toei Animation would continue to make use of the character in their anime adaptation, with Frieza making brief cameo appearances during the Buu Saga, animated features and Dragon Ball GT. He is last referenced in the manga as a measure of the strength of the Kaioshin, the supreme lords of the Dragon Ball universe, as "each of whom could have felled Frieza in one blow." In Toriyama's out-of-continuity parody of his earlier work Neko Majin Z, Frieza sends his henchman Vegeta on errand to retrieve his missing son on Earth.
