I fiddle with my figures a bit sometimes, but as far as play/my imagination goes, it's all about the display. Currently I have a ton of Beast Wars Universe repaints (main show cast characters for the most part) along with some of the Botcon (US and Japanese) exclusives who are engaged in dealing with a time paradox to undo the unmaking of Cybertron (at the hands of Tarantulas similar to the storyline in Primeval Dawn, though my version goes differently and the only ones who can stop him are certain Maximals and Predacons who were on Cybertron after the events of Beast Machines
Time storms, the Vok teaming up with the Oracle/Vector Sigma and Maximals and Predacons reverting to previous forms (i.e. TM2, TM, non-Transmetal etc. etc.) as time passes and the wake of the time storm reaches farther and farther into the future from what Tarantulas did (he destroyed the Ark!).
Ah, the stories we come up with in our heads, it's always fun
