With Apologies to Harlan Ellison/YMMV


 * Complete Monster: The AI Administrator, without a doubt. Killing the BLU team, torturing the RED team, mutating the Spy and  beyond recognition, , she doesn't really know when to quit, does she?
 * The Spy could also count; While no one deserves the fate he got, he does nothing to provide any sympathy for his fellow teammates. Instead, he laughs at them..
 * Nightmare Fuel: AND HOW!
