This is one of the best figures Hot Toys (HT) has produced. It has a good heft and weight - still a mix of diecast and plastic - but has more diecast parts. The articulation is probably the best in all Iron Man figures HT has produced. Check out the video review to see the poses you can achieve with this. It can achieve the ground pound pose.
It comes with a diaroma base which looks very realistic and also a battle damaged piece. The shoulder articulation and the hip articulation in mark 42 is also present in this.
The figure even with it's weight holds the pose it is put in. Check the photos I have attached also.
