I havent seen this done on Charms while ive been here but I think it would be a good idea. Have it set some time in the future so Optimus and all the known Autobots and Decepticons even Maximals and Predicons have been eliminated as time went on. That way we have a clean slate and can easily have our own journeys and battles and sagas. Weather it be batteling Unicron or collecting Minicons we could have our own ideals and stories. Let me know if your interested and if you have any ideas for a story to follow. Let me know through here or PM.
