The Kill Driver is one of Turles' strongest attacks. Turles forms a fiery ring of ki with electricity sparking around it between his palms, then 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. This attack's name comes from the Budokai Tenkaichi video game series. From Dragon Ball Wiki, a Wikia wiki.
