Not many of us can perform the pose in the first image eh? ^^; But Revoltech Arbalest can do it. Apart from the waist and the lack of front skirt armor, another reason is the positioning of its hip joint.
It's not on the pelvis, but is inserted to the rear skirt armor instead. Its movement is not limited to the conventional type of hip joint. ^^ Pretty amazing, and together with those large number of weapons and accessories, this is going to be one really cool action figure. ^^
And a serious challenger to Bandai's already released Robot Damashii [Side AS] version as well. ^^;
December 15th release, 2,400 Yen (inclusive of tax).
