So I can't judge Berlitz, but so far Sapphire is probably my least favourite character. Mainly her tomboyishness, but that's not the only reason >__<
I don't really like Sapphire, either. I don't know.....she just seems really......rude.....and her teeth are disturbing. She looks like a vampire.
Crystal isn't that bad in my opinion. She's just very mature for her age(not physically mature like Blue and Sapphire)
Aw, heck, I'm just gonna make a list. I'm leaving out D/P characters;
Red- I like Red. He
is a bit stereotypical sometimes, but...
Green- Pretty cool. I like how he only talks when necessary. Could lighten up a bit, though....
Blue- My fav character, but she should try getting closer to others. She seems a bit linely, which is to be expected from her childhood...
Yellow- I like her, too, but she seems a bit too innocent....
Gold- He's okay, but he should stop flirting so often.
Silver- Again, I like him, but he should open up more, like Blue should...
Crystal- stated above.
Ruby- He's iffy for me. I think that he's metrosexual. Nothing wrong with that, but I'm just saying that that's what I think he is, not prissy.
Sapphire- Probably my least fav. Stated above.
Wally- My problem is that he was in about 6 chapters and never showed up again. While he did have a Pokedex, I don't think that he's qualified as a main character.
Emerald- Everything.
So yeah....that's my two cents.
