He loves and hates Frieza. He hates Frieza because their father spoiled Frieza, but he also loves him because Frieza is his only brother, as he wanted to avenge Freiza's death.
No, there is no fusion of Frieza and Cooler. It is unknown whether the Ice Demons (Frieza, King Cold, Cooler, and their race) can fuse.
It is unknown for the fusion of Frieza and Cooler is never seen in official canon.
No.
Frieza wasn't killed by Goku , Trucks was the one who killed Frieza and King Cold but Cooler did get mad however when Goku beat Frieza on Namek.
Complete the frieza saga then you will get cooler
Cooler is definitely stronger than Frieza but it isn't known exactly how strong King Cold is.
You have to defeat all the characters 5 times in hardest mode with Cooler and the Last must be frieza. Defeat frieza a 6th time and you will unlock it. It may look wierd, but It WORKS!!!
No Cooler and goku was never matched when goku in his ssj1 but frieza and goku on his ssj1 was matched frieza was only defeated because his body cannot hold up the staggering power of his full power because of the damages he took on the past fights with goku and besides cooler has already used his full power already when goku is in his normal state and even he can cause pain to frieza on his final form frieza can still defeat cooler
You must first have unlocked all characters in the game and have unlocked all bios, settings, etc. When you have done that complete the tournament with Frieza and only Frieza in less than 1 minute(number of seconds in the dragon radar during a battle.) At the end of the tournament when you have completed all requirements you will receive not one but TWO paragraphs about Frieza's domination over earth. You will then receive a message about a mysterious fighter(Cooler) that has joined your selection. Cooler will be available at his second form.
No
Yes, Meta Cooler is much stronger than Cooler. Cooler in his 5th form was defeated by SSJ Goku; however, Meta Cooler was defeated only by SSJ Goku and SSJ Vegeta at full power.
yes they are brothers because if you have dbz budokai tenkaichi there is a skill you can unlock called friezas older brother and when you fuse it with the hatred for saiyains skill you get cooler so that proves cooler is obviously friezas brother. Also they mention it briefly in the movie when cooler comes.
