Ruby and Sapphire and Emerald Chapters have always rubbed me the wrong way.
For one, Ruby and Sapphire went through very a traumatic event when they were young, which switched their personalities. which is weird, as they show no signs of PSD in the earlier chapters.
Second, is that when Ruby stops "holding back" he's kind of a huge jerk! He left Sapphire trapped in Wallace's aircar so he could fight Groudon and Kyogre. I know he was trying to protect her, but he came off as bigoted, as he's seen Sapphire fight before and knows she can take care of herself. What's more, is he even bullied poor Feebas until it left, and when it evolved and he decided to bring it back into his team because it was "beautiful". He's a very shallow character and tends to get most of the action scenes later on in the Chapter.
Third problem I have is it makes it seem like Sapphire was supposed to go back to being girly and Ruby back to being tough, even though it was just immediately contradict everything we've known about them and who they are as characters.
If they're supposed to balance each other out, then they'd probably end up very bland characters overall.
Fourth, Celebi deux ex machina.
As for Emerald, he's a bland character and a definite step down from Wally. Most of his Pokémon are also borrowed from Crystal or belonged to someone else. I know that's probably his thing, but over half of his team consists of tagged-on Pokémon that already belong to someone else. The only exception really being Dusclops.
