Looking up with this Acid Rain figure is easy, it could be just a slight chin lift, a full head lift, or full on arc with the slight torso bend. A slight head tilt or even full on sway of the head is possible.
I like the thickness of the where the more fabric detail is on the neck below, versus a Hasbro figure, where the neck becomes more of a thin stick shape.
I really don't like the double jointed knees here, or on any modern figure. I appreciate stiff joints, but it takes some finessing to get figures to not look like they have severely dislocated their knee joints. And it always seems like knee pads serve to fill that space. Every modern figure seems to have this, but that same design didn't carry into the elbow with a elbow pad to fill the space?
Side by side, the fabric on the figures costume seems more full at the neck on the Acid Rain figure. I still really like the waist joint on the Marauder figure way more than a Hasbro figure. While I appreciate the range of motion on the Acid Rain figures legs, I have found it takes little force to have the legs pop off their hip pegs.
Here is where I think Hasbro could really use an Acid Rain like neck joint, Helix looks like she should be able to straight up, but even with the torso joint, for something that is "modern" or more advanced than the classic G.I.Joe style, the Hasbro figure ends up being more static than action, more block-y than what a the dynamic form of a human could be.
