Combining figures from various lines including "Classics", "Generations", "Beast Wars" and the "Unicron Trilogy", Takara Tomy created the appropriately named "Transformers United" toy line, bringing together characters new and old under one banner starting in 2010. This line often features sculpts released in the US with significant deco changes. Each item is listed with its North American equivalent figure in parenthesis.
The list of items below was copied from the super awesome TF Wiki simply because they organized it incredibly well. BWTF sends its thanks to all the site admins of that site for their fantastic work.
