Although, RD is my least favorite mane six. But to be honest, I don’t like saying her as the “worst”. The stigma of the word itself, it imply she is very bad and I hate her. But I don’t hate her, I still love RD. She is still on my top 10 list of my favorite of pony behind Sweetie Belle. (which is my most favorite filly)
Also in the Past I used to post pics of Coco Pommel a lot. And a lot of people here think that she is my best pony. Sure I love Coco, but because how little the time that she have in the show and little character development, she only manage to get on my top 20 favorite. If she have more screen time and character development, she would be on my top 10 and potentially beat Fluttershy (which is my 3rd most favorite pony.)
