This is my concept of what the Norman could look like in an eventual spidey sequel. I think marvel is going to have to leave the Osborne family alone for a while, but even so eventually I'm sure they'll tackle peters greatest foe.
The goblins look has always been hard to translate in live action, mainly I feel because of his mask. How would Norman talk with a cheap rubber mask on his face, let alone be intimidating? Or if it's not rubber and more like a prosthetic mask designed by Hollywood makeup professionals, does he have a team of makeup artists preparing him before he commits a crime? (FYI makeup prosthetics take hours to apply.)
It's reasons like this that make me understand why Defoe's gobby wore a helmet version of the mask (if only they made it look more metallic as opposed to plastic looking).
Anyway I feel that the best route to take this character while still in the interest of staying comic accurate, is to go low- tech. I'm thinking mid evil chainmail mixed wit her a tactical vest, to incorporate the tunic look. The idea of the suit being made for the military's dosent make much sense seeing as most wars aren't fought on the ground these days (why would they put soilders on gliders?)
