My first reactions to the mane 6:
Twilight: She remained a huge mystery to me at first, like there was so much to her that she wasn't letting on. But within the short amount of time, she the she completely stole the show for me (and my heart! *blush*)
AppleJack: Honestly, I though I was gonna be a AJ fan the first moment I saw her...(I have a thing for Southern girls)
Fluttershy: I have to admit, as cute as she was, I was so concerned that she was going to be the quiet type...like Big Mac only worse.
Rainbow Dash: Loved her instantly, she was so funny and I had a feeling she was going to make me laugh the most.
Rarity: I have to admit I didn't really like her at first. I'm not too keen on "girly" characters.
Pinkie Pie: I'm sure I'm not the only one who wanted to stab her the moment I met her, right?
After I watched more of the episodes, I now love all the 6 mares, but my level for love for them still varies.
