Chaos Next is one of my favorite new Real Head figures, combining the Mirock Chaos Head with the Nextman body. Both the scale and overall look go really nicely together.
The two December releases were shown in this month's Hyber Hobby. The first (green and metallics on flesh body) was a Shinto Gangu store release. The second (metallics on black body) was released at the store's Dec 26 four-man show).
Here are some side by sides for a comparative look at both figures. (Click on each hi-res shot to see the original size):
