Well, I like the Electrode one

And the Slowpoke is pretty cool. They should make one for Hypno.
As for favorite Pokemon overall.... I'd probably be able to narrow it down to one or two for each type...except Normal. Love all normal types pretty much.
Normal - see previous statement
Fire - Vulpix
Water - Slowpoke
Grass - Chikorita/Bulbasaur/Leafeon
Electric - Minun/Ampharos
Ice - Eh, probably Lapras or Jynx
Fighting - Hitmonchan
Poison - Muk
Ground - Hippopotas
Flying - Honchkrow
Psychic - All of them
Bug - Shuckle
Rock - Omastar
Ghost - Misdreavus/Dusknoir
Dragon - Salamence
Dark - Umbreon/Cacturne
