Takara-Tomy have announced a pair of Arms Micron campaigns to celebrate the launch of the Transformers Go! Samurai team. There are three clear Arms Microns paired with each of the three Autobots – a clear A.R.C. paired with Kenzan, a translucent yellow S.2. paired with Jinbu and a translucent red S.W. paired with Ganou. These are included free with a purchase of the corresponding Autobot at certain stores including Toys R Us Japan, Amazon Japan, and Yodobashi Camera.
The second figure campaign is a translucent blue version of the Optimus Prime Blaster Arms Micron, which is available by obtaining a ticket from TV-Boy magazine.
