Well, after looking at all of the new pokemon on Bulbapedia, I'm pretty excited about the new generation. There are more potential favorites for me than I thought there'd be.
The ones I really think I'm going to LOVE are:
Crecelia – So pretty! Shiny and colorful psychic birdie, with a nice shape. Actually there are a lot of birds this time around, but this one's my favorite.
Glacia – Because, I love all the Eeveelutions and all such four-leggers, and this one looks really cool.
Karanakushi – OMG! Sea slugs!!! I always liked sea slugs (nudibranchs) because in real life, they're awesome. They don't sound beautiful or interesting but they ARE. And they made pokemon out of 'em, hoorah!! I especially like the blue guy. :3
And of course, the evolved form Toritodon; but I like the blue Karanakushi best. I don't imagine they're the most powerful or anything, but I don't go by that…XD
Other than that, there's…
Leafia – of course.
Cherinbo – It looks like cherries, how kawaii.
Kolink/Luxio/Rentorer – They're lions, but my first thought was 'blue mouse things with stars on their tails!' Mouse, lion? Could I be more off? It's the ears. Anyway, they're interesting.
Mimilop – A bunny! Looks cute.
Mitsuhoney – A flying honeycomb! Maybe ridiculous, but the thing is mondo cute.
Mantyke – Another favorite aquatic creature of mine is the ray. I love Mantine, and even though this is just a baby version…it's adorable.
Sheimi – Also cute looking.
Keikouo/Neorant – Fishies with butterfly wing-shaped fins! =D I like a lot, particularly Keikouo. Apparently it's based on the neon tetra. Cool, I have about 6 of them!
Muskippa – Fly traps of any sort are neato.
And I like the expression on Nyarmar's face.
Now there are some that I was especially curious about…
PorygonZ. The pic is really small, but from what I see, I like the first two (especially Porygon2) much better.
Lisyan – If it's supposed to be some kind of yellow smiley face, I think that's cute.
Domirror – Intriguing…
Hipopotas – Omg. Possibly the freakiest looking one. That huge snout and those eyes don't seem to go together. Silly.
Mojumbo - Nice to see that old Frykin known as Tangela again! Electabuzz and Magmar too.
Finally, I noted Minomutchi/Minomadam. They're very, very weird. The Steel form covered in building insulation especially…I thought it was cotton candy. O__o I like it though.
