A new edition to the Hot Wheels Batman is the Series 3 1/50 scale (correct me if I'm wrong). The Batpod & Tumbler from the Dark Knight are from the previous series which I missed..... :' (
The 3rd Series are the Batmobile, boat & Batwing from Batman Movie, Batman Return, Batman Super Friends and 1966 TV series.
I don't collect this particular line/series, but once I saw the Batwing, I grabbed it right away. Its the frickin' Batwing from the frickin' (first) movie! Bloody awesome, that.
There are 5 in total, as shown on the back of the cards. I could snatch all five but I didn't like the boat & the Batmobile from the cartoon. So I pass.
