My favorite Pokemon was Vaporeon for the longest time, and I still really like it. But after gen 3 came out, I thought Milotic was a really cool Pokemon and since then it has been my favorite. I don't get into the Pokemon lore and mythology and whatnot, and I rarely bother with pokedex entries or anything like that. I just think it has a wonderful design, and nice stats and movepool are always a plus.
Swinub gets special mention, though, because it reminds me of a little boar named Botan in one of my favorite anime. I'm kind of a Clannad fanboy, if you couldn't already tell from my avatar.
