Fun question: Do you think some Gorn subordinates might have tough-looking piercings in thier head frills? It's an idea I'm just toying with. I've got a friend who makes the most amazing chainmaile jewelry....They otherwise look just like the classic Gorn, with a more realistically detailed surface texture.
I say GO FOR IT! Sounds Kewel, incidently I assume your Gorn is a classic TOS Gorn?
