If Pokemon Special can get rid of the franchise's official mascot on a whim early in the manga, and not have it or any of it's evolutionary line appear in the possession of Ruby/Sapphire, Emerald, Diamond, Pearl, or Platina Berlitz without them losing a significant amount of revinue, they can CERTAINLY do the same in Pokemon.
The anime and the manga aren't the same. As I'm sure you know, the manga follows different characters for different stories. The anime, however, from day one has had Ash and his Pikachu as the central focus.
This is ignoring that the way the manga and the anime are made and marketed are drastically different. Manga is not nearly as easily accessible as the anime. The anime airs in many countries. Manga, at best, gets a small section in major book stores, and most manga is confined to specialty retailors. Some of the Pokemon manga series haven't even made it outside of Japan.
So no, what happens in the manga doesn't automatically translate into something the anime can do well or be beneficial for it, and the same goes for the reverse.
Brock barely has any relevance to the anime, should he be left behind as well? The Orange Islands proved that his cooking skills aren't needed.
If you want to start a Brock thread, go for it. But if you don't want to discuss the point I responded to, then don't bother replying to it.
Less than half of Team Rocket's pokemon barely have anything to do with Sinnoh, either (By that, I mean Meowth, Seviper, and Wobbuffet), should we ditch them in a dirt road and have them catch Gen IV pokemon only?
Team Rocket aren't the central focus of the show. They don't necessarily need current Pokemon to fulfill their roles (though I think it's better when they do)
I'm assuming that, since you post here, you've watched the anime before. I don't think I need to explain to you why Pokemon like TR's Mewoth and Wobbuffet and Ash's Pikachu are relevant to the plot despite not being current regional Pokemon.
I mean, seeing how you think that those that have nothing to do with a saga just need to be left behind,
Also, don't put words in my mouth.
Even if there wasn't a need to have extended appearances, they would at least give them flashbacks or cameos.
They have. Butterfree, for example, has had TWO flashbacks during D/P.
Just for the record, I DON'T seek to turn it into my own personal fanfic. I only wanted to change the show for the betterment of people. Besides, several Animes have been adapted from Mangas (Dragon Ball/DBZ, Love Hina, Battle Vixens (kinda), Naruto, Bleach, all of those things. Did you really think they just started as animes? No, they created them from a source material. That Source Material being the original Mangas.).
That's nice. But the source material for the Pokemon anime are the games. And as I've explained before, the manga and the anime of Pokemon are drastically different in terms of storyline, how they're marketed, and the availability for purchase.
