This looks like it'll be lots of fun.
I wonder if the fine folks at WizKids will respond by releasing figures based on the old Atlas monsters, like Xemnu or Googam. Or maybe figures based on DC's Bloodlines storyline. While this is the only set of images I could find, I know that the original parasites were designed by Arthur Adams, so they'd have a great geek appeal.
Although, this is a great start:
The Mighty ZZZAX!!
My God, I'm such a geek...
