i got some extra heads that i'll be selling...if interested contact me thanks cheers! This head will fit generations kupp (base body for huffer). I've seen this concept from a fellow customizer and kupp's body makes an amazing deluxe size huffer. The custom head doesn't interfere with the transformation at all. Sculpted from scratch, so many many many hours have been put into sculpting and capturing the resemblance to the G1 Huffer. Attention to detail, clean, and sharp lines.
