Frieza

Frieza is an alien and major enemy in the Dragon Ball franchise.

Creation
Akira Toriyama created him from an amalgamation of what monsters looked like to him as a child.

Frieza also means coolness or coldness in Portuguese.

Appearance
See Frieza's race Transformations!

Generally his species is humanoid with reptilian qualities such as three toes and a long strong tail, Frieza first form is a small humanoid with a white chestnut shaped head with two horns with a purple protrusion in the middle, his secondary form resembles his father,his third form resembles the Xenomorphs due to the elongated cranium except a very bulky and stout body, his final form is more streamlined and completely white with purple protrusions on his head, shoulders, forearms and chest and his 100% form is a bulkier version, the mechanized form is a mechanical version of his sleek final form.

Powers and Abilities
Frieza has a vast array of abilities that puts his species at the most feared list. His standard abilities are self-propelled flight at tremendous (estimated by one fan site to be ~Mach 580, although it varies greatly by form) speeds, superhuman (by a factor of millions) strength, and energy projection (on a thermonuclear scale) as well as not having to breathe. At the time of the Saiyan genocide, none of the Saiyans were capable of causing him any sort of physical pain. He also possesses the unique ability to change into more powerful forms if necessary even though his first form is strong enough to destroy a planet. He considers that form to be the weakest unlike his final form which is his true and most powerful form. It is shown that he has telekinetic abilities as well. What credits him to be the most feared and most powerful is that he is nearly impervious to almost any physical harm. Even after having over half of his body destroyed, he was able to survive for at least a year in this horribly injured state without nutrition of any kind. His maximum power level is said to be 120,000,000, though by the time of the Victory Mission Manga, his power level has increased to be almost equal to the combined power of four Super Saiyan 3s. Notably, Frieza was, at the time of his introduction, the most powerful character known, and Goku was only able to defeat him before Namek blew up because Frieza accidentally cut himself in half.

Personality
Frieza appears to have a particularly severe case of antisocial personality disorder, better known as sociopathy. He is incapable of empathy and greatly enjoys the pain of others, prolonging fights he could likely end in seconds simply to see his foes suffer. While he generally acts polite and sophisticated, these traits conceal a violently unstable individual; he lapses into a homicidal, insane rage when angry and usually bursts into laughter when about to kill someone. His violent traits are particularly emphasized in his 2nd and 3rd forms, since he has difficulty controlling himself in those forms. He is also cowardly and arrogant, begging to be saved when sliced in half by his own attack but using the energy Goku gave him for this purpose to attack the Saiyan rather than acknowledge defeat by a "monkey."
