I thought about it, and while I claim to have a large variety of monster characters, I don't really tap into some of the more obscure characters you find in movie monsterdom. And while H.G.Wells's Invisible man isn't really a monster as a supernatural character, Invisible people are often featured in monster genres, such as Monster in my Pocket, several Scooby Movies, and more recently, Igor.

So...okay, like picture this...An exhibitionist flasher...who got hit with an invisible man potion...

Mind boggling.
