From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Garlic Jr. opens the Dead Zone and binds his opponents. The Dead Zone then explodes, inflicting a great amount of damage.
The Dead Zone appeared in Dragon Ball Z: Dead Zone.
It is named Burakku Hōruha (ブラック ホール波, Burakku Hōruha; Literally meaning "Black Hole Wave") in Dragon Ball Z: Kyōshū! Saiya-jin.
