Timelines is a Transformers franchise that belongs to Fun Publications. Rather than having an ongoing year-to-year story from convention to convention, Timelines is a annual series of unconnected stand-alone stories that take place in pre-existing continuities or possibly in new ones unexplored.
Most of the Timelines stories have been made available at the Botcon convention, with an accompanying set of toys featurng characters from the stories.
2005: Descent into Evil and Intimidation Game
2006: Dawn of Future's Past
Prelude to the Beast Wars
2007: Games of Deception!
Others, however, were made available via the Transformers Collectors' Club, usually about recent toys and/or Club exclusives.
