Dragon Fist Explosion! If Goku Doesn't, Who Will? is the sixteenth and final level of the Special Saga in the video game Dragon Ball Z: Budokai Tenkaichi 3. It is based on the movie Dragon Ball Z: Wrath of the Dragon.
Goku will say "It's over" at the end of the battle if Hirudegarn is beaten before the Dragon Fist is used, while Hirudegarn will fall down before Goku says this if beaten with the 1 hit kill Dragon Fist.
At the beginning of the battle, Hirudegarn is invincible. This makes him one of only two fighters (the other being Broly at the beginning of the mission "Blaze: Ultimate Burning Battle") who will not take any damage what-so-ever regardless of the type or number of attacks used.
