This is, by far, the most ... hmm... unique Transformers I've seen on eBay. All you customs fans may like it. As for me, all I have to say is WTF!?!?! Check it out here (what worries me is that there's actually a bidder).
Classics Game Of Deception (set preferred but individuals are OK too)
Most G1 Head/Power/Target-Masters
G1 RoadBuster, Scorponok, Shockwave
Any Optimus Prime (I have tons already but am always looking for more Primes)
Parts Needed: Triggerhappy's Targetmaster gun: Blowpipe (with gun attachment)
