Not really lesser known, but definitely older and, yes, made for Poser.

This is seven times the (almost) exact same mesh.

1. M2P4, a version of Michael that can wear the P4 "Dorks" clothing

2. The original "Millenium Man", here as the "Ruler of Egypt", a set made by Anton Kisiel

3. Michael 2, the 2nd Edition of the "Millenium Man" with a new face and a truckload of additional body morphs.

4. Aiko-Bot, based on Stephanie I. She was "Mystery Mesh" DAZ gave away when you bought Michael 2. Yes, there was an Aiko before Aiko-3.

5. Stephanie I, who was able to fit into V2 clothing by default.

6. Herma, a hermaphrodite character made by Arduino based on M2/Steph I. Fully functional, BTW.  ;-)

7. THE GRIM, a character sold by DAZ based on Michael I/II but with modified rigging.

Also...

MikeTaur, a character I created based on the old DAZ Centaur rigging.

And PosyTaur, made by XAA, also based on the old DAZ Centaur rigging:
