Rayquaza and Yveltal aren't in here? Whaaat o_O
In any case, here's the ones I voted for that were listed:
Gen I legendary bird trio - Just love all these three guys so much, I can't pick a favorite. I'd be happy if any one of them wins :3
Charizard - A. I always pick the fire starters, and B., he's undeniably one of the most iconic mons :P I love his design so much, not to mention his megas. Also...he's the only flying starter? Huh, interesting o.o
Skarmory - A personal particular favorite of mine. I like its typing, and its design is just the epitome of "cool" for me.
Ho-Oh - One of my favorite legendaries, and my preference over Lugia. Love its gorgeous design and its rainbow wings <3 I also love that it has a very special cameo in the very first anime episode, the earliest cameo a Pokémon has ever made before its generation. I'm sure a lot of people have a soft spot for Ho-Oh from seeing the first episode as a kid and wondering what that gorgeous golden bird was for the longest time :) It was the very first legendary Pokémon to be shown in the anime, too...I think it was a very magical moment. As much as I like Lugia, I didn't vote for him in hopes that Ho-Oh can beat him this time >.<
Taillow/Swellow - I've very fond memories of using them in both Emerald and AS, so I have a soft spot for them.

As for the unlisted ones:
Rayquaza - A couple things...Emerald was my first game, green is my favorite color, and his design is
just so badass! The whole Rayquaza arc in the Delta episode was just too amazing for words, and don't even get me started on Mega Rayquaza...
It also gave us one of the best tracks in the series, ever.
Yveltal - Love its design so much that its what provoked me to get Y over X, although I've come to really love Xerneas over time.
Vivillon - Ever since my Spewpa evolved into Vivillon a while ago, I fell in love with it so much that it instantly became one of my top 5 Pokémon, ever. <3 Best butterfly~
Ninjask - I became quite fond of Ninjask ever since it evolved from Nincada in my Alpha Sapphire playthrough. I had used it quite often in my party ever since, and it's among my favorites.
Zubat line - Despite the family's infamy, I quite love Zubat and Crobat. <3 I used a Zubat prominently in my AS playthrough.
Beautifly - Undoubtedly my second favorite butterfly/moth Pokémon. I also used a Beautifly prominently in AS named Sunlight, and used her in quite a lot of contests. :)
