You Hurt Goku!
Ultimate Blow (アルティメットブロー) is a strong punch attack used by Hatchiyack.
To perform the attack, Hatchiyack lunges himself to punch the opponent in the gut, inflicting a great deal of damage.
This attack is used against Vegeta in the OVA Dragon Ball Z: Plan to Eradicate the Saiyans. After destroying Dr. Raichi, Vegeta watches fearlessly as the raging monster, Hatchiyack, forms. After forming, Hatchiyack mutters the word, "Perish" as he uses the Ultimate Blow rush on Vegeta, knocking the Saiyan prince back.
