Frieza
Frieza is a fictional graphic novel supervillain who first appears in the Dragon Ball manga created by Akira Toriyama, followed by Dragon Ball Z and Dragon Ball GT. Frieza also appears in the television special Bardock: The Father of Goku; a few Dragon Ball Z movies and in Dragon Ball GT. He is one of the most powerful major supervillains introduced throughout the Dragon Ball universe. In the gag series Neko Majin Z, it is revealed that he has a son, Kuriza. Frieza is introduced in the series as the powerful galactic overlord on a mission for immortality and conquest, ruler of an empire said to control seventy-nine or more planets. Frieza creates armies from the planets that he conquers, his most utilized race were the Saiyans. Frieza had heard about the legend of the Super Saiyan, a being with unrivaled power, but dismissed it as simple mythology; however, after several Saiyans emerged with rapidly evolving potential, Frieza began to fear that the legend would indeed come true, so as a result, destroyed the Saiyan race. His actions and lust for power eventually bring him into conflict with the heroes of the series when he tries to take possession of the wish-granting Dragon Balls on Planet Namek. 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. (Source: Wikipedia)
