Frieza appears behind the opponent and holds his hand out, ensnaring them in an inescapable golden sphere of energy. He then toys around with this containment like a soccer ball. When Frieza is finished beating the victim around, he kicks the ball away, where it detonates on contact with anything other than Frieza himself. The resulting implosion is so immense it creates a vacuum that sucks in anybody near by.
Frieza uses this attack during his battle against Goku on Namek. When Goku blasts through a large landmass Frieza threw at him, Frieza appears behind him and captures him with the Imprisonment Ball. Frieza spends time smacking Goku around and fires an enormous energy wave at the sphere, blasting it crashing into Planet Namek. However, it is revealed that in the nanosecond between the impact and the explosion, Goku is fast enough to escape not only the explosion, but the vacuum as well.
Appearances in games
It is one of Frieza's Blast 2 attacks in his final form in the Budokai Tenkaichi series; it was originally named Psylock Smasher (サイコロックスマッシャー) in Budokai Tenkaichi 1 and Budokai Tenkaichi 2, but was oddly changed to I May Die This Time (今度は死ぬかもね) in Dragon Ball Z: Budokai Tenkaichi 3. The technique is named You Might Die This Time in the Raging Blast games and Dragon Ball Z For Kinect; in Dragon Ball: Raging Blast 2, instead of Frieza simply tossing the ball back to the ground, he kicks it around for a while until kicking it to the ground.
In Dragon Ball Z: Supersonic Warriors, Frieza uses it as a grapple throw. In Dragon Ball Z: Supersonic Warriors 2, he uses the technique as part of his team attack with Zarbon and Dodoria, the Blind Meteor.
Frieza also uses this technique in Super Dragon Ball Z.
In Dragon Ball: Xenoverse, Frieza's race members use an unnamed variation of this technique when the Ki Blast button is held down. In this version the user takes the same stance Frieza does when performing the Imprisonment Ball, yet it takes the form of a Ki Blast that paralyzes the opponent when it hits. However this prevents the user from firing volleys of standard Ki Blasts like other characters.
