but they're as forced together as Transformers Cybertron was forced into the Unicron Trilogy.

The press release PDF is long gone, but there you go: Galaxy Force was originally a continuation of Superlink (Energon). But then by November, Newtype was reporting that the series was a new stand-alone series.
Besides, Alexis, in her Energon digs, made a cameo appearance in both the last episodes of Galaxy Force and Cybertron (during the press conference with the president and Colonel Franklin). And then TakaraTomy decided to follow Hasbro's lead anyway and incorporated Galaxy Force into what they call the Micron Trilogy.
