Nine-Tailed Naruto Wild Attack

In his initial jinchūriki form, Naruto unleashes a brutal series of claw slashes until he rise-slashes ending with a downward slash, then in an instant releases all built up chakra in a powerful Nine-Tails Burst.

Trivia

 * While Kakashi can copy this with his Sharingan in the first Clash of Ninja game with no special effects on the claw slashes, it is beyond his ability as of Clash of Ninja 2.
 * In both Clash of Ninja 1 and 2, this attack's tracking even when it connects properly tends to be inconsistent enough to allow the victim to escape. This was eventually fixed as of Gekitō Ninja Taisen! 3, where the attack locks the target in place properly throughout the sequence, though a miss can still happen if angled against the walls properly at a sharp angle during an attacking animation in the middle.
 * Despite this secret technique requiring an initial blow, the fact that it is not a cinematic-based attack causes each blow to be affected normally by damage scaling.
 * In the Wii sub-series, shining claw effects are added that slash across the screen per strike.
 * This technique was Naruto's ultimate technique in Naruto: Ultimate Ninja Heroes, where it was named "Nine-Tails Barrage".
 * Likewise, there is a stronger version of this attack known as in the Japanese versions of Naruto: Ninja Council 3; this version is performed in his single-tailed Version 1 form, with its one of its motions involving the grounded-claw-drag based on the 133rd episode of the anime.
