After getting the new Metalhead figure I was quite disappointed with the shoulder articulation, just cut joints! BOoooo I took a Iron Man figure and swapped in his shoulder joints and hollowed out Metalhead's shoulder pad doohickys and attached them. Full repaint!

Figure comes with an array of Magnetic attachments as well:

His Hand
Flame Burst (from McQuarrie Concept Boba Fett)
Saw Blade
Gripper Claw
Blaster

Also, extra add on kit for your TMNT Donny including a headset and remote for Metalhead!
