9POA refers to the articulation of a figure at 5 different points in the sculpt- hence 5 points of articulation.
In the world of DC Universe figures, specially with the Mattel franchise, they usually refer to Mattel's Batman 6-inch figures and even moreso to Justice League Unlimited figures.
Both figure lines may have 9POA but have differing constructions.
- Batman - head, shoulder1, shoulder2, hip1, hip2 + lat1, lat2, knee1, knee2 (no elbow movement)
- JLU- head, shoulder1, shoulder2, hip1, hip2 + elbow1, elbow2, knee1, knee2 (no lat movement)
