Alien Monk (Predator mask) -- pretty much done, need sandals.
Father Nature, Mother Nature's Mate -- almost done, working on staff.
Things I will use:
Gas mask; also have some corrugated tubing if I can work that in.
Dracula Cape (I wear this every year)
Holocaust Cloak (need to find my Grim Reaper Mask)
Undertaker's Hat (I take this every year, too; got it when I was in Pepe Ozan's Opera, Temple of Rudra, 1998)
Lots of body paint!!! :)
