Nothing too major of a custom, just a requested 'Final Battle' Prime showing off the battle damage from the end of the movie. I removed his cab backpack too. You can do this by drilling a notch where the link attaches to his back (leaving the hinge on the truck cab still) and it snaps on and off when you need to transform him into vehicle mode. I nicked and carved Prime all up with my Dremel and files/knives, then gave him a really detailed paint job with shading, highlights, mud splatters, oil splatters, scuff marks, blast damage marks, and all the cool stuff. Added a ball-jointed neck so he could look forward as he ran to tackle Megatron too! GO PRIME GO!
And for more pics, vehicle mode too---->
Final Battle Prime
Enjoy!
