Lightning Release: False Darkness

Kakuzu's lightning-element mask emits lightning in the shape of a spear from its mouth, which then pierces the enemy. Its destructive power is great enough to even pierce through rock; meaning it has a high killing potential. The user can increase the number of spears to attack multiple enemies. This, coupled with the sheer speed of the lightning, makes it a difficult technique to evade. This technique is capable of being focused into a straight beam, similar to a laser.

This was, however, counter-balanced by the Lightning Cutter used by Kakashi Hatake.

Trivia

 * Like the rest of Kakuzu's techniques, the name of this technique comes from the legendary mecha anime . The name Gian was taken from the YMS-15 . The name was altered slightly and given kanji to create the name of this technique.
 * In Naruto Shippūden: Ultimate Ninja Storm 2, Kakuzu uses what looks like the tiger seal to activate this technique, which can be seen in the Boss fight of Naruto and Kakuzu.
