Pain

Pain is how the body usually registers damage.

Pain hurts. Pain is generally bad.

Pain is good when brought to Mary-Sues. Or if one is a masochist.

Pain may be inflicted with a variety of instruments, including but not limited to:


 * Blades (swords, knives, razors, etc.)
 * Clubs
 * Dendric strikers
 * Guns
 * Lasers
 * Rocks
 * Sporks
 * Stale cafeteria food
 * Tasers
 * Vegetables
 * Crucio (this particular example is unique to the Harry Potter canon, but equivalents exist in many universes)

Pain can be caused mentally by really, really bad fanfiction, especially bad smut.
