Dragon Ball Kai Episode 56 English Dubbed Episode Title:I Will Defeat Frieza! Another Super Saiyan!.Episode Description:The mysterious teenager easily takes out Frieza's soldiers, then surprises Frieza by transforming into a Super Saiyan, also traumatizing him in the process. The evil tyrant attempts to destroy this second Super Saiyan, but is unsuccessful. The teenager urges Frieza to use his full power, but Frieza is hesitant to do so (since he planned to save his full power for fighting Goku), though he eventually decides to unleash a Supernova, his most powerful attack on him. The teenager is able to hold back Frieza's attack, and he manages to avoid Frieza's detonation of the energy ball as well. Soon afterward, he slices Frieza into pieces with his sword, before blasting him away. King Cold tries to defeat the Super Saiyan himself, but the teenager easily kills him and destroys his ship. After reverting to his normal state, the teenager spots the Z Fighters and says that Goku will be arriving nearby soon. Despite their skepticism, the Z Fighters agree to join him in awaiting Goku's arrival.
