Great Ape Kid Goku
Great Ape Raditz
The character falls asleep for a few seconds only, during which they are very vulnerable to attacks. If it is successful, the character's health and ki will recover, along with adding all stat bonuses.
In the Budokai Tenkaichi games, the technique is used by Grandpa Gohan, Great Ape Kid Goku, Great Ape Raditz, Cui, Frieza Soldier, Goten, Majin Buu, and Kid Buu. Unlike most techniques, Sleep is part of most living beings (including Humans, Saiyans, and most alien races) natural body functions and as a result, it is one of the few techniques that can be used by anyone (even untrained persons like Bulma) regardless of power level.
