Velcro Ninja

The Velcro Ninja is a character that exemplifies parody type characters by being a humorous take on the normal ninja sterotype. Instead of being stealthy and secretive, he/she has all their weapons attached to their person via velcro. So, when they sneak up on someone and remove their sword for the attack, you hear a very loud, very long version of two pieces of velcro pulling apart.
Man, the characters in "Scary Movie" were all velcro ninjas!
