Just a note about Gygor.
The original idea by Eric was to just do the Shadow Beast reusing Gorilla Grood mold.
It was me suggesting to reuse it also for Gygor. Mattel liked the idea and made an entire new mold for both, but they had been planned together since the beginning (or, better, since we submitted our ideas to them)
Unfortunately that makes the reason for not doing Illumina even less valid: She'd be a tolal of 3 new pieces: head, dress and weapon. All the rest is already a reused mold. So the "new tooling that can't be reused argument" doens't really stand up
