Unite

Mecha-Naruto attaches his mechanical body to Naruto, who wears him as sort of a mechanised suit. Doing this gives the wearer added strength and a few added abilities.

Trivia

 * Mecha-Naruto encasing Naruto into itself and how it functions as a suit is reminiscent to Iron Man from Marvel Comics, especially in the Marvel Cinematic Universe, at least until Mark XLVI (46).
 * Mecha-Kurama does this to Mecha-Naruto in the game Naruto Shippūden: Ultimate Ninja Storm Revolution as their form of the Tailed Beast Mode.
