Arms Micron
- The Arms Microns are a Mini-Con subgroup from the Aligned continuity family.

The Arms Microns (アームズマイクロン Āmuzu Maikuron) were once ordinary weapons. However, a bizarre interaction with Earth's energon mutated them, giving the weapons the spark of life and the ability to transform![1]
This new breed of Mini-Con assists the larger Transformers in the battlefield, combining their powers to form amazing new weapons.

The Arms Microns were only released in Japan. Due to the... interesting variety of Arms Microns, they will be tackled here as groups.

Pack-in Arms Microns

The Arms Microns are the primary gimmick of the Japanese Prime toyline. All Deluxe-and-up releases come with their own Arms Micron, which replaces the accessories from the Hasbro versions (when applicable). Most of the toys have been retooled to add more 5mm post-holes for the Microns to attach to. Each Micron transforms into a weapon, typically modeled after the character's in-show weapon (with exceptions for non-show and repeat characters), and feature numerous 5mm posts and holes, allowing you to combine them together to create larger and more ridiculous weapons. (See "Arms Up" below for more information on combined Arms Micron weapons.)
However, each Micron comes out of the package as an unpainted, unassembled series of parts on plastic runners like a model kit, requiring stickers for detailing. Whether you consider this a good or a bad thing depends on how much work you like putting into your toys.
The Autobot Microns all transform from weapons to humanoid robots. Their names are one-or-two-syllable contractions of their larger partner's names. The Decepticon Microns, however, all transform from weapons to one-eyed animalistic robots, with names based on their animal-form, again crunched to two(ish) syllables, with some slight changes to consonants.

Gacha Arms Microns

A completely new set of molds were created for a set of Arms Microns distributed mainly through Gacha-branded "capsule toy" machines. Oddly, they contain a mix of Micron versions of larger show characters (for lack of information or a better explanation, this wiki is treating them as new characters) and entirely-new bestial Decepticon Microns.
- Vol.1
Wave 1 began appearing in early June of 2012. The toys were also later made available in individual boxes through the Arms Micron Gum series (released on August 20 of 2012), though at a slight markup.
- 1 Optimus Prime Blaster
- 2 Bumblebee Sword
- 3 Zad
- 4 Gob
- Vol.2
Wave 2 appeared in late August of 2012.
- Vol.3
AMW Series
The Arms Micron Weapon Series (aka "AMW series") is a secondary line of individually-packaged Arms Microns sold without any larger companion figure. These vary between entirely new molds and redecoes of partner Microns. They're still unassembled, unpainted kits requiring stickers for deco. They come in identical clear-plastic bags with adhesive flaps, with the assembly instructions printed on the cardboard backer inside.

"Arms Up"
The main gimmick of the Arms Microns is their combination ability, both with larger toys and each other.
Simply attaching an Arms Micron to a larger toy produces an Arms Up Mode. Every AM-series larger robot has at least one specifically-named Arms Up Mode, depicted on their packaging back, utilizing multiple Arms Microns.
Energon Crystals
Every Arms Micron (well, every one that was specifically designed for the Prime toyline, at least) has a socket made for a clear-plastic "Energon Crystal", laid over a small foil sticker showing the Micron's allegiance. They come in a broad variety of colors, and in three different shapes:
| Color | Type | AP (Attack Points, hexagon) | HP (Hit Points, trapezoid) | SP (Speed Points, circle) |
|---|---|---|---|---|
| Light Blue | Pure | O.P. | R.A. | B.2 |
| Bright Salmon | Fast | C.L. | B.H. | Arc |
| Clear | Natural | Zamu | Gora | Igu |
| Amber | Mad | Balo | Gra | |
| Bright Green | Power | Ida | Jida | Noji |
| Purple | Dark | Gul | Gora II | Zori |
| Red | Fake Dark | Shadow Balo, Shadow C.L. | Shadow Gora, Shadow R.A. | |
