In the Energon series, the Omnicons and Terrorcons were capable of creating powerful weapons made from processed energon ore. Each Omnicon and Terrorcon mold came with a unique weapon, made up from multiple parts to serve multiple purposes.
In Japan, Takara took the molds for these weapons and produced numerous special redecoes for promotional purposes, often available for free with the purchase of larger toys. They also packaged new-color versions with the "powered up" redecoes of different characters in the normal retail line.
Hasbro would later create some exclusive energon weapons of their own, but in a much more limited capacity.
