Cooler

Cooler is the eldest son of King Cold and older brother of Frieza. More disciplined and composed than his brother, Cooler possesses a fifth transformation that Frieza never achieved, pushing him to a level beyond Frieza's final form. He clashed with Goku on Earth after recognizing the Saiyan who defeated his brother. Cooler later returns as Meta-Cooler, his consciousness integrated into the Big Gete Star, capable of replicating himself endlessly — making him far more dangerous than his biological form.
