Some of those toys go all the way back to 1984 with the G1 era and some as recent as the Cybertron series and the live action movies. The funny thing is though, the only complete combiners that I have in there is the Optimus/Ultra Magnus and Bruticus from the Robots in Disguise line from 2000. All my older combiners only have partials; Menasaur, Computron, and Abomonus
