This Dragon Ball papercraft is a life size Energy Absorber, created by nadask. The Energy Absorber is an energy collector Yamu uses to drain and collect pure energy for the resurrection of Majin Buu.
Yamu used the Energy Absorber during his attack with Spopovich against Gohan at the 25th World Martial Arts Tournament. Surprised by the increased energy rating on the energy container caused by Gohan's Super Saiyan 2 form, Spopovich and Yamu jumped into the arena to attack him. As Gohan prepared to fight them, Supreme Kai used his telekinesis to restrain Gohan, allowing Spopovich to grab the opponent by the neck and Yamu stabs and drains health health with the Energy Absorber. When finished, Yamu takes the energy container out of the opponent and flies off to the location of Babidi's spaceship with his partner.
At the Southwest Forest, Yamu gives the Energy Absorber back to Babidi, who then kills Spopovich and orders Pui Pui to kill Yamu. When Babidi injects the high amount of pure energy Yamu and Spopovich collected in the Energy Absorber, he realizes he should not have killed them. The Energy Absorber is an item in the video game Dragon Ball Z: Legendary Super Warriors.
It appears in Dragon Ball Z: Budokai Tenkaichi 3, used by Yamu during Spopovich's Ultimate Blast, Majin Buu Resurrection. Babidi also uses it in this game as his Ultimate Blast, Babidi's Ultimate Power, which instead fires a beam of energy at the opponet.
Yamu also uses the Energy Absorber to perform his super attack in Dragon Ball Heroes, Energy Drain.
