Garlic Jr. uses this attack while in his base form during the Garlic Jr. Saga. Lord Slug uses this attack in Dragon Ball Z: Lord Slug in base and Great Namek forms, both against Goku; he uses it as part of his Power of Darkness attack while in his base form, and later upside-down while knocked over in his Great Namek form. Cooler uses this attack, calling it his "Death Beam", while in his base form in Dragon Ball Z: Cooler's Revenge, in which he heavily damages Goku with just one attack. After Cooler is modified by the Big Gete Star, this attack is improved to the Lock-On Buster.
