This clear yellow and black Autobot Firebolt was a free giveaway to children attending the World Hobby Fair in 2012 as well as bonus with the combined purchase of AMW Microns Gabu, Baru, and Dai from TakaraTomy's booth at the Next Generation World Hobby Fair. He transforms into a double-barreled cannon that can be held by any figure with a 5mm post-hole.
The Arms Microns were ordinary weapons that were suddenly brought to life and given the ability to transform when they were mutated by the Energon found on Earth. These new mini-cons can combine their power to make new weapons for the larger Transformers.
