Cooler is the older and more powerful brother of Frieza.
Cooler is the elder brother of Frieza, and is a member of the planet trade organization. Like the majority of Frieza's family, Cooler's history is not well known. Cooler has often complained to himself and to his enemies about his brother Frieza being spoiled and a pest. Despite Cooler being older, his younger brother was the head of the Planet Trade Organization due to him being stronger than Cooler (He confirms Frieza was stronger than him in the Anime: "For a while he had the edge"- Cooler)
Cooler would later surpass his brother with a 5th transformation. Cooler said he would have killed Frieza himself if he had the chance. Cooler, like his brother, was given the task of conquering and destroying planets for the Planet Trade Organization.
Cooler is able to transform one more time than Frieza could. Cooler dramatically increases in height and muscle mass. He forms a large crescent on his head, and develops a face guard. Like his brother, Cooler seems to act more brutally, fighting in a more barbaric manor while losing his sophistication (Like fFrieza did in his 2nd form). Cooler becomes more narcissistic and overconfident in his abilities claiming to be the strongest in the universe. Though his power had grown exponentially, he was still no match for a Super Saiyan.
His Power level, like most villains after the Frieza saga, was never mentioned. It's assumed to be well above 150,000,000 since Frieza's forms dramatically increased with each transformation. (Frieza's 1st form: 530,000, 2nd form: 1,000,000, 3rd: unknown, 4th 120,000,000 (at max) )
Cooler was blasted into pieces after his duel with Goku. Only a small piece of him (his eye) remained. He was able to attach himself to a symbiote like element, which he called the "Getty Star". The Getty star kept him alive. Cooler was able to command the Getty star to do as he wished. He invaded Namek a while after he was defeated by Goku. He was able to produce he current form "Meta Cooler".
Meta Cooler is even more powerful than Cooler in his final form, being able to deal with 2 veteran Super Saiyan toe to toe. If damaged, the Meta Cooler will heal itself, and cure it of it's imperfections. For example, when Cooler lost his arm, he was able to regenerate it and his armor became stronger. When he was destroyed by Goku and Vegeta, the Getty Star saw the problem as there not being enough Coolers, then an Army of Coolers were made was able to over power Goku and Vegeta.
The real Cooler (form un-named) was at the heart of the Getty Star. Unlike his Meta Coolers, he was not able to cure his imperfections.
Meta Cooler's Power Level is Unknown. Meta Cooler however is Stronger than both Android 19 and 20.
Alien Physiology: Cooler's powers derive from his alien heritage, very similar to that of his brother Frieza and his father. This makes Cooler stronger and faster than most humans and other aliens throughout the DBZ Universe.
