It was only a matter of time before fans began customizing the newly released Kotobukiya Rockman model to their liking. Case in point, this ridiculously awesome "Mega Arm" (aka Rock Arm) modification by romlus:
Additional parts intended for a Mazinger Z model were used to create this clever custom, a nod to the weapon of the same name from Game Boy Mega Man V (Rockman World 5) that, when charged, turns Mega Man's fist into a makeshift projectile.
It goes without saying, this is just pure win. Can't wait to see what other kind of zany mods await us!
