Opened the bikes up. Here are some thoughts:
Snake Eyes: The figure itself is frustrating. The detail in the figure is pretty incredible. Unfortunately, as has been known for a while, the articulation is crap, barely better than 1978 Kenner Star Wars figures. And he's severely bow-legged. If not for those shortcomings, this would actually be a stellar Snake Eyes figure, since it's pretty tough to make a decent unique figure of a guy who pretty much wears solid black. There's one other flaw, which I'll mention later.
The bike is nothing fancy, but looks pretty decent. Black, red, and silver is a decent color scheme, but the application of them here is a bit weird (things like a bright red seat on a black motorcycle). I could do without the Arashikage hexagram emblazoned on the windshield (?). There's a pull-back motorized gimmick, but that's neither here nor there for us adult weirdos. :) The set comes with a missile (which is nicely concealed as a headlight, with a concealed launch button behind the seat) and two swords. The swords are unique (so far as I can tell) to this set, and decently-sculpted aside from a noticeable post sticking out from the hilt; this snaps into a connector piece (that looks like a pretty practical hand shield of some sort), which affixes to the handlebars. Unfortunately, the positioning of Snake Eyes' hands makes him look absolutely ridiculous holding the sword (even allowing wrist movement would have helped here tremendously).
The serious flaw in this set lies in the way the figure attaches to the bike. Yes, attaches. It's not clear in the package, but Snake Eyes has a hole in each calf, where a post on either side of the motorcycle inserts. I haven't tried other figures on the bike, but it looks like it's just big enough to cause minor issues in letting other figures borrow his ride. (Sure, this can be dealt with, but I like the vehicles to be usable by multiple figures without having to saw pieces off.) It keeps the figure on the motorcycle, but it also limits how he can be positioned when on it (which is pretty limited already by the position of his arms and his limited articulation).
All in all, for less than $7, I think the good outweighs the bad, but I wouldn't army build it until it drops to $4 or lower. B-
Flint: If I said too much about Snake Eyes, here's where I make up for it. Aside from the head (and I'm not sure if this is the head from the carded Flint, since I don't have that figure), his sculpt is identical to Snake Eyes. The colors border on garish, but are dulled enough to look believable. If not for the stupid Arashikage logo on his chest, I'd probably slap a new head on him and put him on the bike in the background as one of the Eco-Warriors or some other forgotten Joe from the 1990s. The bike is a bit more colorful, with green, silver, orange, black, and gold, and it's like Flint--over the top for a real-world military vehicle, but plausible in the Joeverse. The swords this time are a translucent, almost pink, orange, so they're essentially worthless. All in all, it's close enough to Snake Eyes in quality to also get a B-.
[Since I don't want a Snake Eyes running around on a motorcycle in any scene when there are dozens of better Snake Eyes figures that also better suit his role as a ninja commando, I did a simple headswap between Snakes and Flint. The result looks pretty damned sweet, though I haven't figured out who he is now. :D]
Firefly: This one was a surprise, especially after skimming reviews online. I was on the fence about it, since it's so different from the motorcycle in the movie and I wasn't sure how the gimmick would affect it. But picking it up was a wise choice.
Firefly is completely unique from the Snake Eyes/Flint mold, but with the same level of detail and lack of articulation. The hole in his legs is even situated further down and his hands are positioned at a different angle, so you can't easily switch him to one of the Joe bikes (well, you can, but he's clearly designed for this one). Unless my figure is really jacked up in a way that works to his advantage, there's a pretty cool paint effect that makes his torso look dusty. And, like the others, he's bowlegged enough that he borders on useless in a standing position.
Firefly's bike (trike, really, since it has three wheels) has a gimmick that I can't judge. Mine doesn't work. I'm not sure if it's broken inside (there's something I can hear jangling around) or it's really bad design, but I pushed back the attached wheel and inserted the launching wheel, and it won't launch. No biggie; I'm not going to be launching it around anyway. :)
The triike's design is quite good. It's got that slight science fiction feel that so many Cobra vehicles have, with an appropriate color scheme (grey with silver and orange details). It actually would fit in really well with the Iron Grenadier tech, if any had been produced in the modern line. There are also two side-mounted guns (each of which looks sorta like two upside-down Biker Scout pistols) that are removable for some reason (they're entirely useless otherwise).
Firefly lacks the trademark camouflage pattern on his suit. But that's a plus--if you don't mind Cobras wearing less distinctive uniforms, he makes a great generic. Which means this sweet-looking vehicle can be army-built. As I fully expect this to wind up at some ridiculously low price like $3, I'll probably get a few extras.
FireflyThe "Chopper Viper" looks damned good on the vehicle, so I can forgive the lack of articulation here. I really think they'll look great as escorts for some of the larger vehicles. A
