Well, when the snap out energy sword swings out makes me more happy because the energy sword which makes is just the movie version. So far the Buster Optimus Prime is nice.
Finally, since I bought the TFC-005 which was made by Transformers Fan Project. It's a blaster cannon made for Leader Optimus Prime, Classic Optimus Prime and Alternity Optimus Prime. Since I bought it, I might as well opened it and let my Buster Optimus Prime used to power up a new cannon on his left arm. I even, on the LED light and makes my Buster Optimus Prime complete. It's so cool.
