Not looking forward to spending that much for Junkion troop building? It seems Hasbro has us covered. The only way to get a remolded head on Reveal the Shield Wreck-Gar was previously through the E-Hobby exclusive United Scrapheap. However, now Hasbro's instruction sheet for Wreck-Gar again reveal an alternate head robot in their images. Not sporting a closed of faceplate like that found on Scrapheap, he does have a visored head.
