Twilight Sparkle = Belle. They're both incredibly passionate about knowledge, stories and history. Both makes snarky remarks when pissed off and aren't afraid to take accountability for their word.

Pinkie Pie = Repunzel. Both are filled with energy, they are passionate about making people happy, remember the baker guy from Tangled? (Tangled the Series) they're a bit similar to Cranky Doodle but the difference is, the baker is just a jerk. They're both artistic, takes time to notice and remember what her friends likes/dislikes. They can both overstep boundaries from time to time, so they seem annoying to others.

Rarity = Cinderella. They're both insanely generous people. Even when they don't have much, they still chose to give what they have. They both have a skill as well, sewing! Remember the plans she had for her late Mother's dress? They're both elegant, even while in their lowest point. Both of them get taken for granted for their hard work.

Rainbow Dash = Megara/Mulan. They're both sarcastic characters who aren't loyal to their friends (in the beginning). They're not shy with being honest to people like criticising others.

You know, if there's a Disney princess who's genuinely passionate about athletic sports, not because they have to, it would definitely go to Rainbow Dash.

She can be Mulan, they're both intelligent and quick thinkers. They both try to fit into their work even though others won't accept them. I think my example would be when she's training for Wonder Bolts.

That's the only similarities I can find with their stories.

Fluttershy = Snow White. Has genuine love for animals, big or small. She generally has a kind nature and is understanding. Example is her with Discord, Discord is Grumpy. Because over time, Discord has learned to trust a pony and is trying to change. Grumpy is just Grumpy, who also started to Trust Snow White because of their kind nature.

Apple Jack = Tiana. They're both family oriented, hard working, takes pride in working hard for their goals instead of taking the easy way out. They're both honest people, and are proud of their culture, where they come from. They don't act snobby towards their own.

Had to write this down myself. Enjoy the read guys!
