Recruited to do her bullying for her, often without ever realizing it.
The term borrows its name from the Wicked Witch's winged soldiers in The Wizard of Oz, sent out to do her dirty work while she stays at a safe distance. In narcissistic-abuse terminology, a flying monkey is anyone the narcissist recruits, directly or indirectly, to help control, punish, monitor, or isolate her target. The clinical term for this is proxy recruitment: using a third party to carry out an agenda the narcissist would rather not be seen executing herself.
Flying monkeys aren't always strangers to the situation. They're often other family members, old friends, coworkers, in-laws, or even the family's own therapist or pastor, people whose involvement gives the narcissist's version of events extra credibility, precisely because they seem to be neutral outsiders.
What makes a flying monkey effective is that they usually believe, genuinely, that they're doing the right thing. They relay messages, apply pressure, spread information, or show up to confront the scapegoat "for everyone's own good", often without ever hearing the other side of the story, because the narcissist has made sure they never will.
The role can be temporary or lifelong. A single acquaintance might be used once, for one conversation, to deliver a threat or a guilt trip the narcissist doesn't want traced back to her. Other flying monkeys are recruited for years, becoming a standing surveillance network that reports back on the scapegoat's whereabouts, relationships, and words.
Not every flying monkey knows what they're part of
Gets something out of the arrangement, status, favor with the narcissist, a chance to feel important, or simply the satisfaction of being on the "winning" side of a conflict. This person may have narcissistic or people-pleasing traits of their own, and often knows more of the real story than they let on. They're less interested in truth than in staying in the narcissist's good graces.
A genuinely well-meaning person, a friend, an aunt, a new partner's family member, who has only ever heard one side of a carefully managed story. They believe they're supporting a victim and confronting a bully. When they show up to lecture, guilt-trip, or "check in on" the scapegoat, it rarely occurs to them that they're the ones being used as a weapon.
It usually starts with a one-sided story, told with real emotion, before the target has any chance to respond. A narcissist who confides in a new acquaintance about how "difficult" or "unstable" her daughter is, weeks before that daughter is even mentioned to the acquaintance directly. It's triangulation in practice: bringing a third party into a conflict to build a case, rather than addressing it directly.
Love-bombing frequently seals the recruitment. The flying monkey is made to feel unusually valued, trusted, and important, which builds loyalty fast. You might even be showered with financial gifts. From there, the narcissist only needs to keep supplying selective information and playing the victim whenever the target tries to explain their side. Most flying monkeys never get the chance to hear a fair account, because the narcissist controls who talks to whom, and when, or they paint the story in such a way that the flying monkey is told not to trust or believe anything the target says.
Realizing you were a flying monkey is uncomfortable, but it's not a character flaw. It means the manipulation worked on you the way it was designed to. Go back to the person you were pressuring or judging, and actually hear their account. A real apology, and a willingness to get information directly rather than through the narcissist going forward, repairs more than most people expect.
Arguing your case to a flying monkey rarely works. You're not actually the audience the narcissist is performing for, and trying to "win" them over usually just supplies more material for the narcissist to use. Grey rock applies here too: stay brief, unemotional, and uninteresting to engage with. Save your energy for the people in your life capable of forming their own independent judgment.
If you didn't fully understand that your parent, sibling, or caretaker was abusive, you might have grown up to become an enabler yourself, excusing, minimizing, or normalizing the same behavior in your own relationships without recognizing the pattern.
