Thundercracker (Generations/Henkei)

This has got to be one of my personal favs. Infact I liked it so much I bought a spare incase I broke it. True story.
Couple of reasons why I like Thundercracker, firstly, it's blue. And it's a real solid piece, well constructed and not flimsy. It looks a lot like the G1 version but with more joints for posability. The detailing on this piece is great and for $20-$30 a piece, it's a worthy buy.
