A series of facts point to the conclusion that the MBC is not a real organization but, in fact, some sort of role-play our four protagonists partake in. * A genuine "age-old secret society" wouldn't have a name as unglamorous as the Monster Buster Club. * We've heard that the Monster Busters Club was founded by aliens -- but then they would be calling themselves monsters! * Well, not necessarily. We call certain humans, such as Adolf Hitler or Osama Bin Laden, "Monsters," but that does not mean that we are calling all members of the species "Homo Sapiens," monsters. It's probably the same with aliens- not all aliens are evil, but not all are good. The MBC was probably created to police the bad ones. * A genuine secret society would not have its members dress in such outrage
