I'm disappointed by the starters, so i deposited mine (Emboar), and went to get a Zuruzukin (which evolves into the dark/type mohawk lizard with awesome skin pants). I got disappointed by a lot of Pokémon i had high hopes of... for example, Leopardas (which actually makes Persian seem useful), Braviary (awesome design, awesome concept... and yet terrible speed and evolves at a really high level), and specially the grass starter.
Buffalon also got me disappointed. I was expecting a fast heavyhitter like Tauros, but the thing is slow as heck... totally not going with my 'hit-them-as-fast-as-you-can' strategy.
Also, got a little bit disappointed by the electric eel-lamprey-ultralisk thing. Maybe it's the fact that takes a while to evolve, and the fact that i haven't found any Thunderstones to evolve it to the final stage!
In the other hand, i find Abagoora (that fossil turtle) to be awesome. Cursing and Aquajetting most of its opponents for OHKOs turn it into the definition of epic win for me.
Also, pokémon like Zebraika, Scolipede and Waruvial turned out to be pretty awesome. Maybe i'll go catch that chandelier thing ghost. However, i have to say that Kibago and its evolutionary line are becoming some of my favorite Pokémon (i soloed two of the Unova E4 using only my lv.50 Ononokus).
Oh, but the top of the crown is the black dragon (Zekrom?)... it's simply beautiful.
