I don't think there is a pokemon MMORPG but I believe there is a digimon masters online game kinda like pokemon style where you have a main char and a digimon to use and you get to catch different kinds aswell
mabinogi and dragons nest currently and star craft 2 .. but that's not exactly a mmo
used to play ragnarok online .. trickster .. perfect world .. forsaken world .. maple story .. vindictus .. talesweaver .. final fantasy 14 .. and a ton of others where i would make a char .. get bored after 2 weeks and move on .. LOL
Started out beta testing EQ back in the late 90s.. turned into Anarchy Online, Star Wars Galaxy, Lord of the Rings, WoW (6 months free of it, yay!), and latest- beta testing the new Star Wars The Old Republic which I'll probably play for a while on and off.
Been doing a lot of Dragon Age lately (starting at the beginning with Origins), and Skyrim.
