In the final year of Generation 1, Europe, Canada and Australia saw a handful of all-new toys in the form of the Turbomasters and Predators, as well as more rereleases, including imports of four of the six toys from the Breastforce and all six Constructicons. The latter lacked their combiner parts, for reasons known only to Hasbro. Common theory is that Hasbro decided to exclude them, feeling that combiners would not sell as well as individual toys.
Meanwhile in Japan Transformers went out in a last blaze of glory with Operation: Combination, which saw four all new toys and two rereleases of earlier ones. All were produced in low quantities and are regarded by collectors to be some of the rarest Transformers ever made.
