This is the amalgamated "personal canon" I've been tinkering with for my 25-year-old collection of Transformers toys. Don't ask me why I went to the trouble to do it, or what triggered it, or even if I'm actually gonna do anything with it; it's primarily a way of pulling things together, as well as a way to keep my creative juices flowing when they keep getting blocked. I just decided to put it down "on paper" since I've been referring to it a lot over in the TKT/OnF forums and there's been some curiosity about it.
The continuity is loosely based on G1, with specific references to the original movie, the Marvel comic, and TF: Cybertron from the Unicron Trilogy.
BTW, the graphic is just a placeholder that I'll be replacing when I get home to my own connection.
