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-based weapons.

Design
In comparison to other Formchanges, Nano Arms simply transforms the Keyblade's blade into a broadsword-like nano blade, with twin blades sticking out from the sides. It can transform into a variety of nano, black-shaded weapons.

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 finishers and unique attacks copy elements from various other Formchanges, such as Clock Drill, Blizzard Claws, Hyper Hammer, Storm Flag, and Twin Yo-Yos. The combo finisher has Sora generate a rocket fist and fire it forward.

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
