"It's over when I say it's over. ...And it's over now!"
Cell slaps his opponent away, leaving them unconscious on the ground, completely helpless. Cell then fires an incredibly powerful Finger Beam at them, dealing massive damage.
Time to Die is used against Vegeta during the Cell Games. After Vegeta witnessed Cell kill his son's future counterpart with a Full Power Death Beam, Vegeta goes on a rampage and fires his Maximum Flasher at Cell, followed by shooting many Ki Blasts. Cell emerges from the smoke unscathed and uses the Time to Die slap on Vegeta, sending him flying to the ground. He then uses the Time to Die full powered Ki Blast, which Gohan jumps in front of in order to save Vegeta. Due to this, Gohan suffers a broken left arm.
Appearances in games
Time to Die was named in Dragon Ball Z: Ultimate Tenkaichi and Dragon Ball Z For Kinect, where it is one of Cell's Super Attacks in his Super Perfect form. When Cell uses this attack in Ultimate Tenkaichi, he fires the final blast with two fingers, as opposed to firing it with one finger in the manga/anime. Cell uses a version called Perfect Finisher in Dragon Ball: Tap Battle, where he uses a yellow energy wave in place of the finger beam, and then ends with an extra energy wave. It is also his Blast Spark in Battle of Z.
"Fire powerful Ki Blasts from your fingers! Be careful, as it takes some time before it activates."
