Yamu

Yamu was once an ordinary human martial artist before falling under Babidi's magical influence. The wizard transformed him into a Majin warrior, enhancing his strength while stripping away much of his free will. Paired with Spopovich, another mind-controlled fighter, Yamu entered the 25th World Martial Arts Tournament with a specific mission: use a specialized energy-draining device to steal enough power from the tournament's strongest contestants to help revive Majin Buu.

Unlike the brutish Spopovich, Yamu maintained a degree of composure and tactical awareness even under Babidi's control. When Spopovich savagely prolonged his fight against Videl beyond what was necessary, Yamu was the one who reminded his partner to stay focused on their actual objective. This contrast between the two henchmen highlighted the different ways Babidi's magic could manifest, sometimes amplifying existing brutality and sometimes simply redirecting a more disciplined mind.

The pair successfully drained Gohan's energy during his tournament match using their extraction device, then fled back to Babidi's ship with the stolen power. However, their usefulness to Babidi ended the moment they delivered the energy. The wizard had Pui Pui execute both of them immediately afterward, discarding his tools without a second thought. Yamu's death underscored one of the Buu Saga's recurring themes: that serving Babidi was a one-way arrangement, and that the wizard viewed every subordinate as disposable regardless of their loyalty or success.
