Depending on what kind anime style you want, the entire Aiko/Hiro series was made as an anime/manga style (Aiko, Hiro, AikoToon, HiroToon, Aiko4 Hiro4 etc,) plus NearMe, AnimeDoll and AnimeAlice. There have been a LOT of anime figures made for Poser. I still think the 3rd gen Aiko3/Hiro3/AikoToon/HiroToon are the closes in style and expression to anime (a lot of anime video series were made with them).

If you have the Capsces morph sets for any of the Poser figures you can make them look a lot more anime ish.
