Why He Rocks

 * 1) He has a chill personality.
 * 2) He is one of the famous villains in the Dragon Ball franchise.
 * 3) His rivalry with Son Goku.
 * 4) Having him and Goku fight on Namek not only symbolized how different of an enemy he was, unlike the previous villains like Piccolo, Raditz, Nappa and Vegeta.
 * 5) He is the reason why Goku unlocked his very first Super Saiyan form everyone knows and love today.
 * 6) When he gets defeated by Goku, he would always find a way to defeat him once and for all.
 * 7) All of Frieza's six forms (1st form, 2nd form, 3rd form, final form, 100% form, Mecha Frieza and Golden Frieza) have different, unique and appearances.
 * 8) He is also the reason why Goku went to Earth (Since he destroyed Goku's home planet, Planet Vegeta) and became the hero we know and love today.
 * 9) He is smart. On the battle of Namek, since he knew (their White-Mage)Dende is the one healing Piccolo, Krillin and Vegeta, he chose to kill him first so they cannot be healed. He also knew that he cannot defeat Beerus and Majin Buu.
 * 10) His fights with Goku and Vegeta are epic.
 * 11) His voice actors, Ryūsei Nakao, Linda Young (original), and Christopher Ayres (all media starting with Kai) did an excellent job voicing him.
 * 12) He helped Team Universe 7 fight in the Tournament Of Power.

Bad Qualities

 * 1) His forms, while unique. Some of them (like his third form) can be a bit too terrifying for some viewers.
 * 2) He underestimated Goku while he was battling him on Namek, a key trait for most villains.
 * 3) He's racist, as evidenced of calling Saiyan's Monkeys
 * 4) He killed Krillin.

Trivia

 * 1) His name is a rephrase of "freezer". Akira Toriyama envisioned a fridge when creating him, and so all of his underlings are named after items you would find in a fridge.
