Migrating all that cruft to a separate pokemon wiki was an improvement for everyone, no matter how "notable" you think Beedrill might be, it doesn't need it's own separate wikipedia article. With a separate wiki, Pokemon fans can go into as much depth and lore as they like.
Personally I think the criteria for fictional things should be even stronger. There ought to be an article about the work of fiction itself, but not articles about fictional characters or events unless they're notable outside of the work of fiction.
This keeps wikipedia about facts, not fictional canon.
e.g. Pikachu derves a separate article, Charmander does not.
To elaborate further, the Charizard article has a "Physical characteristics" section.
It's a anime / computer game. It's not a physical being, so any "physical characteristics" is not factual information, it's fictional information. Wikipedia does a poor job at separation of fact and fiction in articles about fictional beings.
