I didn't see a thread for Mixels, and greatly appreciate the General threads. The most recent discussion thread was about Series 6.
My daughter and I discovered Series 7 Mixels (scheduled release: February 2016) at the local Fred Meyer two nights ago, and she chose the Medivals as the first 3 that we would purchase. These are probably better as parts packs than characters on their own. I suspect that Camillot will be a very popular buy for parts collectors, as it had 4X black stud with hole in it and 2X metallic dark grey cone, among other great parts.
One thing surprised me: the Nixel which came with Paladum has a weapon! When I got to the end of the Mixel build, I thought I had missed a piece and it turned out to belong to the Nixel. There's also apparently a Nixel with stars in his eyes (I assume that one comes with the MCPD family).
