DBZ Episode 120
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The "mysterious youth" confronts Mecha Freeza, King Cold, and their soldiers. The soldiers attack the stranger but get sliced into pieces. More soldiers charge at the boy but they are easily handled. Frieza and King Cold laugh thinking the stranger will be no trouble at all, one of the soldiers survives the attack and begs his commanders for mercy Frieza responds by impaling him with his hand killing him.. The stranger announces that he knows Goku and is a Super Saiyan. He transforms into a Super Saiyan and the Z Fighters wonder if it’s Goku they are sensing. Frieza tries four times to defeat the stranger all failing. He fires a Supernova at the stranger, ten times the size of the Death Ball that destroyed Namek. He just catches it and destroys it without trouble. "Is this yours?" he asked Frieza. Frieza blows it up and thinks the stranger is dead, but he survived the explosion. The stranger then shouts to Frieza that he's still alive and launches a Burning Attack, Frieza barely dodges it, and looks up to see the stranger with his sword cut him in half.
- Mecha Freeza is killed by Future Trunks.
- Future Trunks vs. Soldiers
- Future Trunks (Super Saiyan) vs. Mecha Freeza
- The energy orb that Frieza uses in an attempt to destroy Earth is similar to the one he used on Planet Vegeta.
- A scene is edited out in the edited version where the soldier backing away from Trunks is impaled by Frieza with his hand, leaving many viewers of edited dubs confused as to what happens to him.
- It took Goku about 19 episodes to defeat Frieza, and even then Frieza survived. However, Trunks kills Frieza in one episode (though the full scene of Frieza's death isn't shown until the beginning of the next episode).
- Although the edited version has no problem showing Frieza being chopped horizontally in half by his own energy disk, it never shows Frieza after he has been chopped vertically in half by Trunks (though we can tell from the way it shows Frieza's view splitting in two), except in flashbacks during the Android and Cell sagas.
- This is the last episode in Dragon Ball Z where a scouter is used.
- In the Manga Freeza actually never attacks Future Trunks more than once, he only fired one blast at Trunks, before Trunks yelled at Freeza and launched his Burning Attack at him. The other attacks after Freeza's first blast, were filler, added in the anime.
