Turles forms a ring of energy with electricity sparking around it between his palms and throws it at his target. The resulting explosion is quite powerful, and apparently enough to kill a Great Ape. The downside of this technique is that the center of the ring is empty, meaning that if the targets are small enough, they would just slip past the hollow center and be unharmed by the attack, as seen in Gohan's case when he was restored to his normal form by Goku.
Turles uses this technique against Great Ape Gohan when his attempts to regain control of Gohan failed and resulted in Gohan targeting him instead. However, Goku saves Gohan by cutting off his tail with a Tail Slicer.
Video Game Appearances
Kill Driver was named in the Plan to Eradicate the Saiyans video game, where it is also used by Ghost Raichi. Kill Driver is one of Turles' Blast 2 in the Budokai Tenkaichi series, and he also uses the attack in Dragon Ball: Raging Blast 2 and Dragon Ball Heroes. When the Kill Driver is used against small opponents like Kid Gohan in those video games, it damages them, despite the fact that in the movie the attack does not affect Kid Gohan, as he passed right through the circle.
In Dragon Ball Z: Extreme Butōden, it appears under the name Killing Ring (キリングリング) and is Turles' Z-Assist Support attack.
"Fires a Ki Blast. Repeatedly tapping the button will cause the blast to grow larger. Pressing the button again will cause the Ki Blast to explode."
— Dragon Ball Xenoverse 2 Tutorial Description
In Dragon Ball Xenoverse 2, Kill Driver appears as one of Turles' Super Skills, which the Future Warrior can learn by completing School Quest: "Lesson 1" of Turles' Training. If charged to the max the ring will be larger and more powerful, though like in the film it is possible for an opponent (especially small opponents like Kid Gohan) to travel through the center of the ring unharmed which is more likely to occur when fully charged, though this weakness is somewhat mitigated by the ability to detonate the attack with additional input, thus even if the opponent manages to travel through the center of the ring, they can still be damaged by explosion produced by its detonation. After the 1.09.00 Update, it can be added to Bardock's custom skillset after purchasing it for 5 TP Medals..
