Underrated Ponies.

I always liked Cherry.

Twist. Where did she go? Into the background because she had a cutie mark. We never see her and AB interact again. Same problem with DT and SS - they fade into the back once they’re no longer villains.

Minuette. She was a treasure, but they didn’t use her.

Flitter. Does anyone remember her?

Cheerilee. She had a lot of potential input in CMC plots, but she wasn’t used to the extent she could have been. The persistent hints that she’s single and unhappy didn’t go anywhere. And she was mostly obsoleted at the end by the friendship school.

I love Flitter! She’s just so adorable.

At Mare Fair somebody was going around with a clipboard polling people on their favorite and second favorite ponies. I put Flitter as my second and was told I was the only person who had ever mentioned her.

I also love Lily. She’s adorable too.

Silverspeed. It’s strange how the fandom never noticed this one.
She appeared (and was called by name) in one of the best episodes of the show (Hurricane Fluttershy).

You’re absolutely right! She is criminally underrated.
