DragonballZ saga information

this is in my opinion the best DragonballZ saga. the saga explains a lot about Goku 's past and has some amazing fight scenes. Piccolo is revived and transported to the planet Namek where he merges with Nail to become a super Namek. when Krillin is killed by Frieza something inside Goku snaps but what does this mean can Goku really defeat the universes biggest tyrant Frieza? this is the point Goku transforms into the Saiyan 's most powerful form a SuperSaiyan this is what I believe to be about the best fight scene in the entire dragonball series.
