I have no idea what he looks like under the mask, my gut tells me they never came up with a design. It looks like his goggles could be removable though?
They look to me like they are a separate piece of plastic - if they aren't intended to come off, they still might come off easily after putting them in hot water for a minute - like Aurra Sing's ponytail or any other "appendage" for that matter.Is that the SAGA/OTC Jabba's Palace Cape?
Those are NOT obsolete - they are awesome. Maybe you could paint the yellow parts a different color? Perhaps blue? And make your own squad. They are far from being obsolete Fritz!
