I think the anime has a bias in favorof unevolved Pokemon and a bias against evolved Pokemon and A lot of people say that the Pokemon do not evolve so soon because they want to give a message to children that you do not have to be big to win which is true, however this is still bending the rules of Pokemon there are other ways that you can show that a unevolved Pokemon can win against a evolved Pokemon by having them battle a evolved one before it evolves or have short person be a main character to show that small people or creatures can be successful. They also made most of notable the girls characters in the anime coordinators as well which I consider a gender stereotype. I think they also have a pro bias toward Red of the Generation I video games since Ash was based off of him and he was used in ever season of Pokemon. (And yes I am aware that Ash is in Pokemon mangas as well.) By the way Ash's Pikachu is in second stage evolution so it is not considered an unevolved Pokemon like Dawn's Piplup or most of the other Pokemon traveling with them.
Bias not only exist in the anime, but in this manga although there are not as many bias as there are in the anime because they made One example of bias in this manga is that they made all. They made the male protagonist of each arc to be the only ones to make it to the sem-finals in the tournament and no female characters or even the male characters who are named after the second version made it to the semi-finals. They could have mixed the characters together and still Emerald still be the winner. Do not get me wrong I still like this manga and really enjoy reading it.
Platina battles both gyms and complete in contest where as Dawn from the anime completes in contest which is really stereotypical on Dawn's part. I think that the anime need to show that there are some girls who love to battle gyms and want to compete in the Pokemon league. I hope they do consider that if a fifth generation video games comes out.
I am not bashing the anime or this manga if you think that. I am just stating facts and I have a right to make critism because I do approve of everything in my favorite animes, mangas, video games, tvshow, novels, etc.
