Cool topic! I actually might come back here time after time. ^_^
Emboar- I named him Boom. I have no clue why I got him except that I thought he was kind of cute. I really wanted Oshawott, but the week B/W came out, I suddenly didn't. I felt like Tepig would be better, and so I tentatively chose him. Never regretted it; he's my favorite.
Simipour - I was roaming around, trying to get a Tympole. And I suddenly saw a Panpour and. I felt inclined to choose it. So I caught it, named it Pudge, and he's just been so awesome. I really like this monkey.
Cinccino - I was EV training my... Beheeyem I think. And I was training on Defenses I think, and I found a Shiny Minccino. I caught it and boxed her. However, I revamped my party and felt like i might as well give her a shot. The open slot in my party could be filled by her. And again, perfect fit! I really liked her, so I named her Duchess.
Beheeyem - I was reading a story on the serebii forums and they had a Beheeyem. And it made me consider it. And then I saw Elgyem in the anime and it was so cute! So I caught one, and I loved it. I named it Leonard from Big Bang Theory.
Scrafty - He's bulky, he can learn Fake Out, and Ash's Scraggy and the Scraggy from the Manga Pokemon BW: Good Partners made me really want one.
Musharna - I always found them cute. I always liked their bulk. And I figured I might as well! It was between Musharna and Gothitelle, and I just liked Musharna the most. Telepathy's pretty cool (and then I realized that I'm not using Surf OR Earthquake, so. It wasn't THAT useful, but I liked it). My favorite TR abuser too, plus she works well with Teammates. I'm renaming her Penny from BBT.
Jellicent - I always likedloved the stache. Nuff said. His name is Bob, from Monsters vs. Aliens.
Carracosta - It was suggested I get one for my party and, after using one in my Black play through, I was quite impressed with him. ^__^ His name's Rafiki.
Eelektross - When I found out about his typing and ability, I was just so excited for him! I thought he was ugly though, so I was a little unsure. Then I saw his in-game animation, and was like. AW. He's cute! In some odd way. @__@ He's my second one and he's named Zazu.
Druddigon - I love Dragons. Not my favorite type, but I love Dragons. And after watching the anime, Druddigon just looked so cool! So, I got one. He works better with my team than Haxorus, or any of the other dragons, and I don't like Hydreigon. I named him Roscoe, after the big mean dog from Oliver and Company.
Lickilicky - I LOVE THIS THING. She's so cute! And then she gets Cloud Nine, has such an abundant move pool, man! She's definitely one of my favorites. Her name is Pookalooz, taken from one of the those Disney Dolls.
And then, the last 7 are mainly chosen because of their Speed. They're so slow and work so well in a Trick Room. ^___^ That, and they're all some of my favorites. haha
