The Energy-Suction Device (エネルギー吸引機 Enerugī Kyūinki) is an energy device that allows the absorption of energy. Yamu used this device in order to absorb energy from Gohan to revive Majin Buu.
Yamu uses the Energy-Sunction Device 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 jump into the arena to attack him. As Gohan prepares to fight them, Shin uses his telekinesis to restrain Gohan, allowing Spopovich to grab Gohan by the neck while Yamu stabs him and drains his energy with the Energy-Suction Device. When finished, Yamu took the device out of the Gohan and flies off to the location of Babidi's spaceship with his partner.
At the Southwest Forest (the spaceship's location), Yamu gives the device back to Babidi, who then violently 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-Suction Device, he realizes he should not have killed them.
Video Game Appearances
The Energy-Suction Device is an item in the video game Dragon Ball Z: Legendary Super Warriors under the name Eneegy Absorber.
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 part of his grappling throw (he stabs his opponent and absorbs their energy), to hit his opponent, and during his Ultimate Blast the Babidi's Ultimate Power, in which the absorber is used to fire a beam of energy at the opponent. After 3 grabs, this blast becomes one of the strongest moves in the game.
It also appears in the main story where it is used by the Masked Saiyan to collect enough Kili for Towa to power up Mira. After the energy is collected, Towa releases the collected energy into Mira, powering him up. Interestingly, it has the same M mark as the one used by Babidi and his henchman.
- The design of the Energy-Suction Device bears some resemblance to a Genie's lamp.
