Note #1: While Hasbro has not publicized it, a repaint of Insecticon was displayed at San Diego's Comic-Con International in July of 2004. This item resembled the color scheme of the toy on the package of the regular Insecticon figure, which was different from the final product. A packaged sample was never available and as such, a final name is not known. Reader Monzo pointed us to this image at ASM that shows the toy in a convention setting, OTFCC 2004. Monzo also indicated that Hasbro informed him that this was to be a running change and not a new figure.

Note #2: Before Energon was officially released, advance packaged samples of Ultra Magnus with a repainted Street Speed Team appeared on eBay. The final US packaging shows these toys, and a small batch of these Mini-Cons were created, making them some of the rarest repaints in the world with a handful of units seen on the collector market. The final toy, which was rare in and of itself, included a repaint of the Space Team.

Note #3: Items "Energon Megatron" and "Energon Optimus Prime" are unnamed items that showed up as unpackaged samples on the Web. These items were never released or displayed by Hasbro in any official capacity.
