Of course there's also my two...both Z and Mitzi are Gretels, Z has the old-school head bought new at JunkySpot, complete with asymmetric eyes, no eyepockets, and slightly bigger than the "new school" Gretel. Mitzi is a "new school" Gretel, with eye pockets and a slightly smaller head. Z cannot wear a 7-8 wig, but must have a 8-9 wig instead. Mitzi can wear a 7-8 wig although it should be one with a stretchy cap.

L-R: Z, Yumiko, Mitzi and Namiko
I think that Rainman made the Gretel face distinctly Korean. This has influenced their back-stories. According to their back stories, Mitzi is Korean-American and her grandfather got political asylum in the US because he worked for UN forces during the Korean War. Z's mom is a Korean woman born in Japan to a family that had lived in Japan for two generations. She married Z's dad Nobu and the two emigrated to the US. Z's maternal family actually turned out to be related to Mitzi's family...they are second cousins. Oddly enough, Mitzi and Z's wife Yumiko Natsume were friends since second grade, when they were the only two Asian children in a class full of Latinos, punctuated by a few blacks and a few whites.
So yeah, Yumiko's friend turns out to be Z's cousin. And oh yeah: she plays drums.
