I think RD has a bigger ego than Rarity…I mean, shit, she brags about what she was does far more than Rarity does :P

@PonyPon  
She hides it. Usually pretty well but the high score isn’t entirely unjustifiable. It’s especially evident in the first couple seasons but it still pops out here and there. I’d say “13”.

I agree, Applejack is only brave in matters where she’s already confident. Similar to her fear of Zecora (which Apple Bloom overcame much easier than she did), her treatment of Apple Bloom in “Somepony to Watch Over Me” was also caused by cowardice. Likewise her unwillingness to let anypony know what happened to her in “The Last Roundup;” she was terrified of what their response would be, and rather than confront it, she fled. That’s not bravery.
 
Pinkie’s pretty much fearless, but I’m not sure it’s bravery so much as “fools rush in where angels fear to tread.” Twilight should have higher bravery. She’s rushed in when situations seemed pretty hopeless, not out of a lack of fear, but because she knew it had to be done. That’s practically the definition of bravery. (But she shouldn’t have a 20 because she’s so terrified of disappointing Celestia.)

Ego should be at least 5 on Twi.
 
Shy would be in the negatives.

Applejack is not that brave. Apple Bloom would be 20.
