It's recently occurred to me after reading this blog and other blogs doing read throughs of the pre-reboot Archie comics that Penders Echidnas are basically like Elves in various fantasy settings. Particularly High Elves. The most advanced species in the setting who often act superior to everyone else (and are treated as right for thinking so by the writing) and are very seclusionist. The Dark Legion could even be like Dark Elves/Drow.
Yeah, it’s a super common trope in fantasy and sci-fi–the quote unquote “peaceful” enlightened species with amazing technology under attack from its more “primitive,” aggressive neighbors
Of course then Penders had his elf echidnas be at war with some weird dingo version of Nazi Germany or something so the allegory there is all just a big mess
