Lightning Straight

While covered in Lightning Release Armour, the Fourth Raikage runs towards the opponent and punches them at maximum speed.

Trivia

 * Though A referred to this as just his "fastest punch" in the manga, this technique is given an explicit name in Naruto Shippūden: Ultimate Ninja Storm 3.
 * The only two shinobi to have ever dodged it are Minato Namikaze with his Flying Thunder God Technique, and Naruto Uzumaki while in Nine-Tails Chakra Mode.
