I was that anon asking about Hakaider's posablity the other day, and I just got 'em in the mail today. Okay, see his arm holding the gun there in the picture? That's the most it can bend. You can forcibly swivel it at the elbows but the joint isn't designed to do that.

The legs, that's about the most it can split sideways, there's a lot more forward and backward motion but they tend to bend towards the sides at an awkward angle, think Revoltech Kenshiro's hip joints.

Despite the shortcomings you can expect from an early SIC, it's a very cool figure, especially the bike. I'd definitely recommend picking him up if you're into SICs. Also, sorry for the atrocious phone cam pic.
