"Simian bastard! I am Lord Frieza. None surpass me. No one even comes close. Etch this into your skull; I am emperor of the universe, the likes of you are only fit to grovel at my feet. Or better still, to die in disgrace at the hands of your MASTER!"
First, Frieza draws his right fist to his side and charges a purple energy sphere. Then, he brings his hand forward and fires an emanating purple energy wave at the opponent, inflicting a large amount of damage.
Frieza uses this attack against Goku in his Super Saiyan form. After Frieza is accidentally dissected by his Death Saucer, he begs for mercy from Goku, who gives some of his energy to the tyrant and flies away. However, Frieza does not accept defeat and fires the "You Will Die By My Hand!" energy wave in his final attempt to kill Goku. However, Goku counterattacks with an Angry Kamehameha, overpowering Frieza's attack and seemingly killing the tyrant (although it is later revealed that Frieza survives albeit severely maimed).
Appearances in games
The attack is in a cutscene that reenacts the manga/anime scene in Dragon Ball Z: Budokai. The attack was named "You Will Die By My Hand!" in Dragon Ball Z: Budokai Tenkaichi 3, Dragon Ball Z: Tenkaichi Tag Team, and Dragon Ball Z: Burst Limit where it appears as Frieza's Ultimate Blast in his 100% Power form. With its name changed to I'm the One Who'll Kill You!, the attack also appears in the Raging Blast games, Dragon Ball Z: Ultimate Tenkaichi and Dragon Ball Z For Kinect. It is also Frieza's ultimate attack in Dragon Ball Z: Battle of Z, called I Will Kill You.
In Dragon Ball Xenoverse, this technique is referenced by Frieza's Z-Soul, "You must die by my hand!", which activates upon being KO'd negating said KO and reviving the user while increasing Ki Blast Super power. Equipping this Z-Soul increases Basic ATK and Strike Supers by 3 while decreasing Health and Ki Blast Supers by 3.
"Release a super-powerful energy wave! It won't use any Ki, but if your Health is low, you'll only be able to use it once!"
— Dragon Ball Xenoverse 2 Skill description
In Dragon Ball Xenoverse 2, it appears as an Ultimate Skill used by Frieza in his 100% and Golden forms under the name Last Emperor which can be obtained by the Future Warrior (Xenoverse 2) as a reward in Parallel Quest 71: "Abominable Saiyans" or by purchasing it from the TP Medal Shop (open from Friday to Sunday) for 30 TP Medals. As it does not use up Ki (even though 3 Ki bars are required to perform it regardless) when performed, it can only be used once per battle and only when the user has reached low health (though not mentioned in its description the skill remains unusable until the user has reached low health) which fits with its use by Frieza during the climax of his battle with Super Saiyan Goku. As such, it is a hit-or-miss attack and functions as a reverse of Breaker Energy Wave.
