UPDATE: check a more recent and up to date post of UFC action figures.
I find that sometimes the problem with action figures (and statues as well although to a lesser extent) is that they don’t look quite like the characters or people they’re trying to represent. Some of UFC action figures kind of look pretty similar to the real fighters, some at least. There are a bunch of figures available, just check the youtube video below.
Don’t forget to visit these guys where I first saw the video: http://www.aroundtheoctagon.com/?p=3339
