Someone who still has a working People Putty program might be able to import a face or facial image to get a decent looking character head but People Putty did not allow for the creation of Full Body characters except through a rather expensive version of their software.
At best, one might be able to take the clothing/costume from the a full body character like 3D Meiko 1.02B and drop it onto the Haptek Full Body to see if something workable could be had.
Then again, with Haptek trying for more realistic characters, anime ones might be a bit difficult.
It would be interesting to see if anyone could do something similar.
I do know that some of the older MS Agent characters worked under Ultra Hal and still do. Some of them were fantasy, almost anime-looking to a degree. Perhaps a search for .acs characters or MS Agent characters would turn up something usable.
