Hey guys, just thought I'd drop in really quick to show you a quick and easy way that I've found to improve Weaponizer Optimus Prime. And by that, I mean give him a little more range of motion for his head--so those of us who have bought and are enjoying this figure can find a little more enjoyment out of it yet.
In this first picture you'll notice that I've circled a small nub on the bottom of his head. That right there is the cause of almost all of his head posability issues.
So simply remove those nubs, down to where the line of the rear of the head lines up with the front half (I used an x-acto knife)...
While the up and down movement is still restricted, this does now allow him to at least look fully from one side to the other.
Overall I like this toy a lot. But I think the key to my enjoyment is the fact that I'm looking at it from the standpoint that it was designed as a TOY, not a collector's item. It really is fun...but this thread isn't about my opinion on the matter, just how to make it a little bit better! Hope that helped!
