Yamu is a simple Earthling before being brought under Babidi's Manipulation Sorcery, making his appearance presumably change drastically and giving him unnatural powers. He also became very pale and brutish in nature. He is not nearly as big as his partner, but his muscle mass is still incredibly high.
Yamu seems intelligent and sane than Spopovich due to being able to control his power.
Dragon Ball Z
Majin Buu Saga
Yamu is paired up with Spopovich and sent to the 25th World Tournament to gather energy for Babidi, the evil wizard. The energy they are sent to gather is needed to awaken Majin Buu. Just as Spopovich was about to murder Videl, Yamu then angrily orders him to stop fooling around.
After Kibito and Shin ask Gohan to turn into a Super Saiyan 2, Yamu and Spopovich enter the ring and drain all of Gohan's energy with the Energy-Suction Device, with Shin deliberately paralyzing Gohan, so Shin could later follow them. Then they fly off to their master, while unknown to Yamu and Spopovich, Shin and some of the Dragon Team are following them. After Yamu and Spopovich give the energy to Babidi, the wizard decides to kill Spopovich, feeling he is no longer useful. When Yamu sees this, he tries to escape but is killed by Pui Pui, one of Babidi's head cronies, using his Pui Pui Nice Shot.
