I've had this odd red enlarged LEGO-esque piece in my LEGO stuff for as long as I can remember. And I always thought it would make a good Red Hood head (hood?) - The problem? It didn't actually fit over a minifigure's neck piece.
Well I finally busted out the drill-bits and made it fit! unfortunately, I drilled too far and instead of the little LEGO nub at top, now there's just a hole. I am considering gluing a nub up there so his head looks like an enlarged LEGO head piece, but the hole is ok for now, and only a problem if you look at him from above!
I like the effect, because Red Hood is a guy (The Joker, sometimes Jason Todd) with a helmet over his head. A simple red LEGO head piece wouldn't have had the correct effect. This looks like a LEGO red dome over a LEGO head! I added the Red Hood to a LEGO tuxedo piece I have, and gave him black gloves...maybe white gloves would be better? He is also holding a BrickArms grenade launcher.
