[Anime] Ash and the Elite 4

But yeah, the Manga is indeed inaccurate. Blue is supposed to have Squirtle (In the anime, Gary has Squirtle as his starter, so the manga writers ignored the "Rivals always have a starter that has the advantage over your starter" logic and gave him a Bulbasaur, even though he's Blue (Green in the Japanese version)), Green's supposed to be a girl and have a Bulbasaur. Ruby is supposed to have a Torchic, and Sapphire's supposed to have a Mudkip. It's like in Snake's Revenge where there's 2 different plots. Listening to the Game's plot, you're taking on Big Boss, while reading the manual, you're taking on Higharolla Kockamamie.

Speaking of Sapphire, there should be an anime about Sapphire (I am referring Yuki/Brendan as Sapphire).

Pokemon obviously have 2 different plots IIRC.
