This Gatling Bumblebee Store Exclusives was released by Takara Tomy in Japan. Gatling Bumblebee is part of the Transformers Prime Arms Micron toy series which is exclusive to Japan and includes a miniature transforming minicon piece. The Arms Micron Mini-Cons brings a whole new dimension to the Transformers battlefield with a new arsenal of accessories Transformers can wield exclusive to this series.
Part of the first wave of Prime: Robots in Disguise Weaponizer Class toys, Bumblebee is a large, roughly Leader-sized mold with a simplified transformation scheme, more accurate proportions, and a grand total of four fake wheels on his person due to said transformation. He comes with a double-barreled blaster pistol which can mount onto his hands, forearms, and trunk.
His main gimmicks, however, are the two large mini-guns hidden in his hood-chest, which can deploy and "weaponize" either mode. When his robot head/engine block is pressed down, the mini-guns swing out from his hood-chest and spin, while a red LED inside his torso lights up briefly. Pushing on the gray lever/the center front fender portion (both on his chest) briefly lights up the LED again and swings the mini-guns back into his body.
