P-P-P-P-P-P-POWER!
.... I really do think they re-used Baymans face model for Rig. They may have altered it somewhat, but there is just way too much in common there. I'm pretty much positive Bayman was the base for Rig. I don't think there is any plot reasoning for this though.... its probably the same thing they did with Ayane/Eliot, or what Namco did with Yun/Zwei. Re-used assets and all that.
