Nano Arms

Nano Arms (ナノアームズ) is a Formchange in Kingdom Hearts III. It allows the user to transform the Keyblade into a variety of nano weapons.

Design
Nano Arms transforms the Keyblade into a nano-bladed broadsword with twin blades sticking out from the sides. It can then transform further into a variety of black-shaded nano weapons, which resemble the Clock Drill, Blizzard Claws, Hyper Hammer, Storm Flag, and Twin Yo-Yos Formchanges as well as a Rocket Fist.

Mechanics
In Kingdom Hearts III, Nano Arms is the Formchange of the Nano Gear Keyblade, associated with Blitz Form. It has a base duration of 30 seconds and a maximum combo length of 6. Its basic attacks are identical to Sora's basic attacks, but its Nano Transform ability allows it to copy various other Formchanges for its ground and air combo finishers, gap closer, ground-to-air, and air-to-ground attacks. Its third and final combo finisher has Sora form a fist out of nano and firing it forwards.

The Finish command has Sora leap into a portal before generating several other portals around himself and firing streams of nano out of them.

Kingdom Hearts III
