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. These weapons resemble the Clock Drill, Blizzard Claws, Hyper Hammer, Storm Flag, and Twin Yo-Yos Formchanges.

Mechanics
In Kingdom Hearts III, Nano Arms is the Formchange of the Nano Gear Keyblade, associated with Blitz Form. Its basic attacks are identical to Sora's basic attacks, but its Nano Transform ability allows it to mimic attacks from various other Formchanges. Its first and second ground combo finishers respectively mimic Blizzard Claws' Winding Strike and Hyper Hammer's Ground Wallop, while its first and second air combo finishers respectively mimic Clock Drill's Dire Drill and Twin Yo-Yos' Backspin. The third ground and air combo finishers are the same, in which Sora forms a nano fist and fires 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
