Narcissist
"Grandiosity is the defining characteristic of narcissism. More than just arrogance or vanity, grandiosity is an unrealistic sense of superiority. Narcissists believe they are unique or “special” and can only be understood by other special people. What’s more, they are too good for anything average or ordinary. They only want to associate and be associated with other high-status people, places, and things.
Narcissists also believe that they’re better than everyone else and expect recognition as such—even when they’ve done nothing to earn it. They will often exaggerate or outright lie about their achievements and talents. And when they talk about work or relationships, all you’ll hear is how much they contribute, how great they are, and how lucky the people in their lives are to have them. They are the undisputed star and everyone else is at best a bit player."
