Lightning Release Chakra Mode

By wrapping his body in a layer of lightning chakra, the Fourth Raikage can electrically stimulate his nervous system and speed up his neural synapses to react faster to danger and push his physical prowess to the absolute limit, allowing him to gain tremendous raw speed and monstrous power. This armour, combined with taijutsu, allows A to utilize nintaijutsu.

While using this technique his reflexes are comparable to that of Konoha's Yellow Flash, making it difficult, even for the Sharingan, to keep up with him. By combining this armour with the Body Flicker Technique, he can even dodge Sasuke's Amaterasu at a split second, as well as Jūgo's Cursed Seal Chakra Blast at point blank range. Despite the incredible speed given by the technique, A himself admits that Minato was still faster than him.

The armour also increases his defense, drastically reducing, if not completely negating, damage from incoming attacks as even a direct Chidori from Sasuke was barely able to pierce his chest. In addition, the armour seems to increase his strength, though this could be part of his own natural abilities.

In lieu of tailed beast chakra, the Raikage uses this lightning armour to empower himself when performing the Lariat, producing the same effects due to his high-powered chakra.
