Four Legs Technique

This technique grants animal-like accelerated fighting instinct and reflexes to the user. By enveloping their entire body in chakra and moving on all fours, they can obtain high speed movement and reflexes like that of a wild animal.

Taught only to the members of the Inuzuka clan, this technique forms the basis of a Inuzuka clan member's taijutsu fighting style, and will add even more to their feral-like appearances; their canine teeth, their finger and toenails grow to claw-like length, their eyes also become more wild with their pupils becoming slits.

When under the effects of this jutsu, an Inuzuka will display great feats of physical strength, speed, and endurance. The form is best suited for using and supporting the ferocious "hit-and-run" tactics that the clan is well known for, leaving the enemy barely anytime to launch a counter attack.

Trivia

 * While Naruto Uzumaki is known to be prone to maneuvering on all fours on occasion in his normal state, he'll also experiences a number of other changes similar to this technique when he goes through his initial jinchūriki form.
