V4.2 is the base

V4.2 Morphs ++ is the product which adds the morphs for figure versatility

V4.2 Creature Creator is another set of morphs for adding non-human features

Aiko 4 is an add-on morph set which makes the figure look more like it's in the Japanese anime style

She-Freak 4 is the latest additional morph set to add

These are just the DAZ3D ones.  There are others like the Vittorio 4 Male set by pdxjims, for example.
