Beacon is a redeco of the Energon Saber Mini-Con Wreckage, transforming into a Cybertronic starship, as well as forming the tip of the Blizzard Saber sword. He was sold as part of the second Micron Booster assortment in Japan, in individual, blind-packed boxes so you did not know which Mini-Con you got until you opened the box and opaque black plastic bag inside.
The same mold is also used by Sunstorm. The original version of the mold is used by Jack and Runway.
