There are two main line Takara Tomy versions of Ultra Magnus (MP-2, MP-22), Starscream (MP-3, MP-11)and Skywarp (MP-6, MP-11SW). The second versions of Ultra Magnus, Starscream and Skywarp are generally considered better versions because of the superior moulds. There are three main line versions of Optimus (MP-1, MP-4, MP-10) and there are debates over which Optimus is better.
