1:Dazzlings. (They’re awesome, competent and even a bit funny at times. Plus, epic songs all around)  
2:Midnight Sparkle (Intimidating as hell, and also…its evil Twilight, do I really need to elaborate?)  
3:Wallflower (Adorable, yet also a bit sad when it comes down to it. Also, her thing about removing memories and being forgotten was a very interesting concept all things considered.)  
4:Gloriosa Daisy (Eh, I would have preferred if Gaia Everfree was real rather than her being the villain…and for such a petty reason too. However, she had a really cool musical number as well as awesome plant magic.)  
5:Sunset Shimmer (I love Sunset, I really do, but she was nothing but underwhelming as a villain. Plus, her demon form is more goofy than scary when it comes down to it)  
6:Juniper Montage (If they just kept her powers to her magic mirror, then she wouldn’t be too bad, but when she transformed into a monster form just like Sunset, Midnight and Gloriosa did earlier, with no new cool feature added to it (instead only managing to be less threatening than Demon Shimmer), then all respect I had for her as an antagonist went out the window. It didn’t help that she somehow managed to worf all the main characters except for Starlight (who just happened to be there by pure coincidence), and then get stopped with a single short friendship speech from someone she just met.

Adagio and Wallflower are my top two.  
I like Sunset as a good person. She was terrible as a villain.

Hold it! We’re gonna have a seventh coming soon.

1- Dazzlings (How can someone be badass and cute at the same time? Maybe the reason why i love them is because they sing beatiful (at least only with he collars lol) and because i wanted to see more of them, probably they are the most powerful of the six villains but the rainbooms stopped them at time)  
2- Wallflower (His reasons to do what she did weren’t selfish at all, she didn’t want to be in the Sunset’s place or dominate equestria, she wanted to Sunset be in her place, becausue without realizing it, she made her feel very bad. And she did maybe one of the worst things to Sunset and the girls without the need of transform into a demon, and she also said to Sunset, face to face, that she hated her)  
3- Midnight Sparkle (I would like to say that her and sunset satan are in the same place because i like both and i would say that midnight is just a Twilight version of Sunset satan, and the concept of an evil Twilight, at least in EG, is awesome)  
4- Sunset Satan (A bit predictable and boring but i still liking her)  
5- Gaea Everfree (I only like her musical number, but his reasons to do what she did were selfish and dumb)  
6- Juniper Monstar (Weak, boring and it’s evil transformation makes no sense)

A lot of green recently.
