The biggest enemy
Frieza is one of the most important antagonists of the anime series and the manga Dragon Ball Z. Frieza is an alien and although he only appears in the second part of the manga, when Goku learns that he is an alien, he is the one who motivated Goku’s parents to send him to Earth. He is the undisputed leader of the universe 7. He has his own army and his cruelty makes him a leader feared by all. He will face Goku several times, notably on Namek and then in the tournament of power when he replaced Good Buu in the Universe 7 team.
