Here it goes:
FAVOURITES
Bug --- Volcarona. Probably obvious, but he's one of the most well designed Pokes
Dark --- So many to choose, (Vullaby, Darkrai), but I'll go with Zoroark. It's just- cool
Dragon --- I'm really leaning towards Gen V, but Haxorus reeks coolness
Electric --- Raikou, again, it's just cool and well designed
Fighting --- Scrafty. I love how they mixed a lizard shedding its skin and a gangster
Fire --- Heatmor, strangely. I liked it's fire tongue, and the fact it can learn Bug Bite I find hilarious
Flying --- Staraptor, again cool, and an awesome name to match
Ghost --- Giratina is a great, unexpected Pokemon. Both of his formes are awesome
Grass --- Lots to choose (Snivy, Sawsbuck) But my favourite is probably Roserade
Ground --- Excadrill. The way it turns into a drill in the anime is really clever
Ice --- Lapras. It's just really mysterious... and enticing...
Normal --- So many I love (Minccino, Stoutland, Snorlax) but my favourite is Togepi, because it's so adorable. Sprites and sugi artwork don't do its anime counterpart justice
Poison --- Drapion for its awesomeness. Pauls is brilliant in Ash's final battle with him.
Psychic --- My favourite type, but I'll have to go with Reuniclus. It's on my White Team, I love it
Rock --- There's not many Rock Types that I like, but I'll have to go with Roggenrola. I laughed when I saw its name, and it looks like a Bom-omb
Steel --- Bronzong. It's really peculiar but is surprising relevant and well designed to a tale in Japanese Folklore
Water --- The largest type, the largest choice. I love ones like Psyduck, Staryu, Piplup, but my favourite is probably Oshawott. It's really adorable, and despite the rage against Samurott, I think it's the best way it could have evolved without looking boring and samey
LEAST FAVOURITES
Bug --- Weedle, it's so silly how it eventually evolves into a bee. I love how prior to platinum, it couldn't inflict damage on steel types.
Dark --- Liepard. From my experience in white, it gets really annoying
Dragon --- Going to have to say none. I don't dislike any of them.
Electric --- Zapdos, I just don't like it. Probably because it reminds me of big bird from Sesame Street
Fighting --- Probably have to say Cobalion. It's design is just really mismatched and generally weird
Fire --- Magby. It's eclipsed by the cool entity of Elekid
Flying - Golbat. They're really annoying, and so far have killed two of my loved Pokemon in my Diamond Nuzlocke -.-
Ghost --- Not really one I hate, but I'll go with Dusclops since in game, Battle Tower, Elite Four Phoebe, it can be REEEEAAAALLLY annoying
Grass --- Again, not really anyone that sticks out, but I'll go with Lileep. It's just... I don't know what it... I'm confused
Ground --- Stunfisk. It's just got no purpose whatsoever.
Ice --- Jynx. Whenever I see it I just think... why?
Normal --- Purugly. It's all in the name.
Poison --- Swalot. Because.
Psychic --- Despite Reuniclus being my favourite, you can't deny that the curl on Solosis' head is a sperm cell
Rock --- Probopass. There was no need for it. I like a quirky design, but the iron moustache is stupid
Steel --- Klinklang. I know there's only so much they could've done with Klink, but evolving doesn't count when you just pick up another gear
Water --- Simipour's dreadlocks look stupid. And it also became annoying on the Battle Subway once, you never like loosing your Pokemon and then having your foe mocking you *just smile and wave Simipour*
