Her movie jumps around in time and her relationship to her superpower changes. All of these unknowns and variables make it hard to pinpoint her Enneagram. Let’s look at what we know at the beginning of her timeline.
She’s a pilot, a test pilot. Daring, physical, brave. She’s a beloved friend. She’s your basic Eight: outspoken, competent, and naturally heroic. Because Hollywood’s default position for most women superheroes is Eight, Carol is an easy call.
Reviews of the Captain Marvel movie and the Carol character are mixed. I recently watched it and can barely remember what happened. I’m going to say that’s because she’s an Eight. Nothing stands out, nothing distinguishes her. It’s too trope. She’s a cardboard cutout of a superhero whose powers are so hypercharged nothing poses a challenge against her. It’s hard to write plot conflict for a character like this, which is why she comes in as a deus ex machina in Endgame. Perhaps future iterations of her will develop into something more.
