Dark Energon Ultimate Weapon COMPLETE

This can only be completed if you buy all 7 Kre-O sets of the series 2 release. They include Wheeljack vs. Knock-Out, Megatron vs Optimus, Cliffjumper and the Vechicons, Barricade and the Autobot Troopers, Stealth Bumblebee, Vortex, and Devastator.
Each set comes with little Kre-O Energon looking parts. They are a clear purple (really easy to spot in the bags). On the back of each box it says collect them all to create the Ultimate Dark Energon Weapon. The catch to this is that there is NO instruction booklet on how to put it together once you have all the pieces! You have a little picture that you have to figure out on your own how it goes together. I've been working on it for a couple of weeks. Avoiding YouTube and the internet because I wanted to figure it out on my own. Last night I sat down for an hour and I think I finally figured it out. Here is my interpretation of how it goes together.
I have plenty of pics so you can take a look at what I think. This is the best I can come up with.

Overall, it's not bad. It looks best with Series 1 Megatron. If you decide to use any of the other characters, it just looks clunky and doesn't seem to look right on them. Plus, it is Dark Energon...Only one guy can really be the sole holder of that..........
