Haretsu Majyutsu is a spell used by Babidi.
With a sharp gaze, Babidi transmits his thoughts to the opponent, making their blood convulse. This rapidly swells the opponents body and makes them explode. Using this technique, Babidi is also capable of making only the person's head explode. Those attacked by Haretsu Majyutsu die while screaming in agony, with contorted features.[1]
Babidi uses Haretsu Majyutsu on Marvin
Babidi first used it after Yamu and Spopovich brought him the energy they had taken from Gohan to make Spopovich expand and explode, not being useful for Babidi anymore. Babidi later used this spell to force the head of Marvin, a World Martial Arts Tournament staff member, to explode for bothering him with useless information.
