Transformers Dark Of The Moon Mechtech Voyager Megatron
KO means "Knock Off " which means that this product has been made by a producer that is not the original. The molds and figure have been made to match the original as a bootleg version. The price and some build errors account for this, most of the time. This is not the original version, just a less pricey clone.
