|Type||Ki Manipulation Technique|
The Brain Crash Hammer is a powerful ki-based technique created by Gotenks.
The technique itself is similar in essence to Kuririn's own Kienzan. To use the technique, Gotenks raises his hand into the air, forming a large blast that tears the opponent's body into pieces directly down the middle. This technique was used by Gotenks as a Super Saiyan 3.
