Snagged the Black Dragon VTOL at Walmart recently. Went back today for the VAMP Mk. II.
As far as I can tell offhand, it's identical to the previous VAMP except for the color. It's green this time around instead of tan, which is a cute "color reversal" of the original VAMP, which started out green, and its "Mk. II" was tan.
I pondered in the thread about the VTOL, which has no labels, whether the massive number of labels that came with the first VAMP would accompany the second. Yep -- they do. So, if I had any weekend plans...

Anyway, maybe this time around I won't lose the ^@!&%&^@%#& dashboard label.
Steel Brigade Delta is a cool figure. The file card made me raise an eyebrow, since it described the Steel Brigade as the "grunts" of the Joe Team who want to work their way up to specialized individuals. I'd always seen the Steel Brigade as a special group of top-secret specialists that did stuff that even the Joes couldn't quite touch.
Conversely, except for the fancy helmet (and is that a Snake-Eyes head under it -- or something that could pass for one?), this guy looks more like a general soldier, lugging around about ten tons of equipment so he's ready for any conceivable situation. So maybe the Steel Brigade has been repurposed or something.
