Egomaniacs

Egomaniacs (also called narcissists) are individuals who suffer from narcissistic personality disorder. They have a delusional sense of self-worth and are NOT the same as an Arrogant Antagonist, though many people do confuse them - in simple terms an Egomaniac is obsessed with themselves and believes they should be the center of attention, an object of worship/reverence and so forth. Many megalomaniacs are egomaniacal as they are certain attention-seekers.

Arrogant antagonists often try and bully people - Egomaniacs on the other hand are decidely more deranged: a person who demands statues built of themselves or has their image pasted in every available area of his or her empire, for example, goes beyond Arrogance and is an Egomaniac.

Many Egomaniacs also react extremely poorly to anyone trying to humble them, rejecting their advances because they believe that they are simply not giving them the respect they see themselves as deserving - this can cause them to lash out in a fit of narcissistic rage, making them much more dangerous than a simple arrogant snob or bully.

Two easy (but rough) ways to identify if an antagonist is an Egomaniac: If said antagonist use the words "I" and "me" a great deal or constantly refer to themselves in 3rd person.
