'''Basic Trope''': An evil product has a warning on the label declaring it to be evil.
* '''Straight''': Killer Kola is a PsychoSerum which has a small print warning label on the can declaring that it may contain traces of evil.
* '''Exaggerated''':
** Killer Kola is a PsychoSerum that has a huge yellow and black warning label on the can declaring it might contain tiny amounts of evil.
** The label is ridiculously small.
* '''Downplayed''': "Killer Kola may contain baby tears, virgin blood, and various other ill-gotten ingredients."
* '''Justified''':
** The company that sells Killer Kola does not want to be sued by someone for not listing evil on the ingredients list.
** Killer Kola works on a [[DealWithTheDevil contract with hell]]. Insidious shrink-wrap contracts work but only if it makes its nature [[ObviouslyEvil abundantly clear]]. Hell only has a claim on those who give themselves to it.
* '''Inverted''': Goody Gummy Bears has a label declaring it contains massive levels of goodness.
* '''Subverted''': Killer Kola doesn't have a label declaring traces of evil.
* '''Double Subverted''': ...Unless you view the can under a black-light.
* '''Parodied''': The label reads "May contain traces of [[PlaceWorseThanDeath New Jersey]]".
* '''Zig Zagged''': ???
* '''Averted''': Killer Kola doesn't contain evil.
* '''Enforced''': ???
* '''Lampshaded''': "Look, it even has a warning label!"
* '''Invoked''': The [=FDA=] won't let the Killer Kola Company sell its products unless they stick the warning label on.
* '''Exploited''': Killer Kola is a completely normal soft drink. The "evil" warning label was only put there to appeal to [[TeensAreMonsters edgy teenagers]], [[TerroristsWithoutACause rebels]], and {{Card Carrying Villain}}s -- all of whom would have gladly committed evil deeds, PsychoSerum or no.
* '''Defied''': "What, ''warn'' our victims they're ingesting evil? Screw that!"
* '''Discussed''': ???
* '''Conversed''': ???
* '''Deconstructed''': With such an obvious warning label, it doesn't take long for the Trope City police department to connect Killer Kola to a recent, massive spike in murders and arrest the Killer Kola Company's [[CorruptCorporateExecutive evil CEO]]. Plus, people boycott the company.
