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 (near-light) speeds, superhuman (by a factor of millions) strength, and energy projection (on a thermonuclear scale) as well as not having to breath. 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. His maximum power level is said to be 120,000,000. 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 is one of the most sadistic characters in the Dragon Ball universe, and is likely responsible for the deaths of millions if not billions. He makes liberal use of his planet-destroying powers, and quite obviously enjoys doing so, as seen by his laughter and appreciation of the "fireworks" during the genocide of the Saiyans. On a more personal level, he spends nearly twenty minutes physically and psychologically torturing Vegeta, despite the fact that he could have killed him in a matter of seconds. Earlier, he impales Krillin on one of his horns and keeps him there for three minutes (the last of which is spend bucking Krillin around, causing him incredible pain), at one point even licking Krillin's blood off of his face, before tossing him in the ocean. His sadism led to his downfall when he accidentally induced Goku's Super Saiyan transformation by causing Krillin to explode. After Goku gives him the ki he needs to leave Namek after his bisection, he uses it to attack Goku, resulting in further injuries when he is hit by a ki blast, which in turn leaves him trapped on Namek as it explodes. He is no less evil after being rebuilt as a cyborg, and impales one of his own men for retreating from Future Trunks.
