Evil Sounds Deep/Playing With

Basic Trope: A villain has a deep voice, signifying their evilness.
 * Straight: Emperor Evulz has a deep voice.
 * Exaggerated: Evulz has a voice so inhumanly deep that it destroys the eardrums of all who hear him speak.
 * Downplayed: Evulz’s voice is only slightly deeper than Bob's.
 * Justified: His voice just naturally sounds like that.
 * Inverted:
 * Evulz has a high voice.
 * Bob has a deep voice.
 * Subverted: Evulz has a deep voice, but when he takes off his helmet, it turns out to have been the result of his mechanical suit.
 * Double Subverted: ...But the unmasked voice is the result of a separate voice modulator he used as a ploy to make himself seem less evil. His voice really is that deep.
 * Parodied: Evulz's voice is so deep that his subordinates can't even understand what he's saying.
 * Deconstructed: Evulz has significant trouble getting into a position of power, because anyone with half a brain can tell that he's evil on account of how he sounds.
 * Reconstructed: This angers him to such an extent that he starts actively using his voice to terrorize all who dare oppose him.
 * Averted:
 * Evulz has a normal voice.
 * Or everyone has a deep voice in the setting, the heroes included.
 * Enforced: "We need to let the audience know that Evulz is a villain. Let's make his voice really deep and menacing."
 * Invoked: Evulz designs a voice modulator that will deepen his voice, so that he'll be more recognizably evil and intimidating.
 * Defied: Evulz has a deep voice, but then he realizes that this is an easy way for others to tell that he's evil, compromising his plan for power. He decides to use a voice modulator that will make his voice sound normal.
 * Lampshaded: "Evulz is definitely evil. Just listen to that voice of his."
 * Discussed: "Haven't you heard? Villains always have deep voices."
