KANTO - 9
because, Pokémon was something else. I mean, I loved the weird épisodes like : -ep34 and Tarsan ( Seriously, a Tarsan-like in Pokémon). -ep22 with Natsume and some Psionic power...-ep18, the beauty contest with Kojiro's boobs -ep38, the virtual Porygon and the virtual world -ep15 -ep18...... And a lot of other épisodes
There were weapons, real animals....
But Satoshi didn't get all of his badges fairly (kinda)..... He hasn't always battled :/ . Finally, he has some great Pokémon and Gen I is my fav :P
Edit: And Rocket-Dan was the best. All of their gags were new and it wasn't boring because it's the first time they appeared :P
. I can add the same reasons that the post below too =] (Titanium)
ORANGE - 7
because it was short and Satoshi got 4 badges and win the league. Maybe it was a little league but he won it (at least). He fought a Kairyu :D
Lizardon obey him, he got a Kabigon . Kenji got a awesome Sutoraiku
JOHTO - 7
Don't remember well but If we remove the fillers (F*cking GS ball), it's was great. Good gym battles, Satoshi got a shiny <3 , great Pokémon ( I love them)
HOENN- 7,5 Even If Kasumi left, Haruka and Masato were not that bad. Plus, I loved Harley interaction with Haruka O_o . It's the beginning of Pokémon Contest, something that's new to Pokémon. Contestshipping
SINNOH - ? I've seen a few épisodes but I'll watch more of them =] . But it seems annoying because there are 192 episodes only for sinnoh :/ ( 192 ( or 193^^) episodes for Hoenn and the Battle Frontier ) --'
BW- 4 but When it'll finished, maybe I will change my mark =]
