Right on. The Lunataks devolved far too quickly, but when first introduced, they were a refreshing change from the Mutants (who had also devolved). In addition to the design and characterizations (both of which I agree with you about), I really loved the voice acting on them. TugMug was maybe a bit too ... un-PC, perhaps? ... but Lypton's Luna and Hyman's Red Eye were both pretty radical and different from anything they'd done on Season One. Raphael's Chilla was excellent, and Doug Preis as Alluro still floors me (Pattenred after James Mason a little bit, apparently? Lynne Lypton implies as much in her interview on this site).
