I pinpointed all the mane 6 on their enneagrams and how they act under stress….

Rarity - The Helper

Rarity: Oh, I see. After I go out of my way to get you tickets for a show, and this is how you repay me?! By abandoning me in my hour of need?! Oh, oh, oh! Fine! Go and see Hinny of the Hills tonight! And then tomorrow when you come to see my fashion show without any fashion to show you can have MORE entertainment! Oh why look, there’s our friend Rarity going down in FLAMES! ISN’T FRIENDSHIP MAGIC?!

-Rarity Takes Manehattan

Can be manipulative and self-serving, instilling guilt by telling others how much they owe them and make them suffer. Abuse food and medication to “stuff feelings” and get sympathy. Undermine people, making belittling, disparaging remarks. Extremely self-deceptive about their motives and how aggressive and/or selfish their behavior is.

Twilight- The Investigator

Twilight Sparkle: Clock is ticking, Twilight. Clock. Is. Ticking. Keep it together. If I can’t find a friendship problem… I’ll make a friendship problem!

-Lesson Zero

Get obsessed yet frightened by their threatening ideas, becoming horrified, delirious, and prey to gross distortions and phobias.

Rainbow Dash - The Achiever

Rainbow Dash: Rrgh, there are absolutely no freak natural disasters going on anywhere! How am I supposed to prove myself when everything’s so normal and safe? [gasps] Hold it right there, Granny Smith! You don’t have to pretend with me. I can see that you’re in way over your head here.

-The Mysterious Mare Do Well

 Fearing failure and humiliation, they can be exploitative and opportunistic, covetous of the success of others, and willing to do “whatever it takes” to preserve the illusion of their superiority.

Applejack - The Individualist

Applejack: Nothin’ doin’, Twilight. I’m gonna prove to you, t’everypony, that I can do this on my own. Ow! Now if you’ll excuse me, I’ve gotta go help Pinkie Pie.

-Applebuck Season

When dreams fail, become self-inhibiting and angry at self, depressed and alienated from self and others, blocked and emotionally paralyzed. Ashamed of self, fatigued and unable to function.

Tormented by delusional self-contempt, self-reproaches, self-hatred, and morbid thoughts: everything is a source of torment. Blaming others, they drive away anyone who tries to help them.

Pinkie Pie - The Enthusiast

Pinkie Pie: You know what? I’m not gonna speak to them ever again. And I’m not gonna invite them to another party as long as I live! They don’t deserve to be invited to my parties. [plink] Not after the way they’ve been acting.

-Party of One

 Desperate to quell their anxieties, can be impulsive and infantile: do not know when to stop. Addictions and excess take their toll: debauched, depraved, dissipated escapists, offensive and abusive.

In flight from self, acting out impulses rather than dealing with anxiety or frustrations: go out of control, into erratic mood swings, and compulsive actions (manias).

Fluttershy - The Peacemaker

Fluttershy: [muffled] Pinkie’s right. I’m the only one to blame. [normal] But don’t worry, I’m never coming out of my house again. Everypony will be a lot safer with me and my mean mouth locked away.

-Putting your Hoof Down

Can be highly repressed, undeveloped, and ineffectual. Feel incapable of facing problems: become obstinate, dissociating self from all conflicts. Neglectful and dangerous to others.
