Frieza is (in the beginning)the strongest being in the universe.
Frieza is from a powerfull race:Challengers.They have a strange language.
Frieza has got many man.He has 2 bodyguards,Zarbon & Dodoria.
But,Vegeta killed Zarbon & Dodoria.The first time we see Frieza is in episode 39:
Frieza shows off.He destroys a Namek Village and kills everyone.
He collected all the 7 Dragonballs.Also,Frieza has got lots of men,and he also posses
the strongest figthing-team in the universe:The Ginyu Force.
Even if Goku (& Vegeta)kills the Ginyu Force,Frieza still wants 2 figth.
Frieza is very powerfull.He faugth with Nail and Nail loses like u never seen b-4.
Frieza hates Saiyans,he always kills them,he killed the whole planet,including King Vegeta
(father of Vegeta) and Bardock,father of Goku.The Frieza Saga has taken much much time.
At the end,Goku wins from Frieza.Well,Frieza did a enery disc and kills himself with it.
Later,Goku gaved him energy.But Frieza was still bad.Goku flies away,but afther he saw that
Fieza attacks him,he easily kills him.
Later,Frieza is rebuild 2 a Frieza Bot and flies with his father,King Cold,in a spaceship 2
Earth,Trunks kills the Frieza and King Cold.Frieza was always scared of the legend of a Super Saiyan.
Maybe Frieza should take a look in the Buu Saga,were there are 5 Super Saiyans(including Brolly).
