If you can describe a character to a T in one word and it is a common trope word, that character is probably not a very good one.
- "*****y"? Nah. How about "self-assured, antagonistic, fierce, and hard to get along with, but Ash is not daunted by her"?
- "Delinquent" could be better as a character who disregards the rules but strictly adheres to his personal morality due to finding flaw in the structure of society.
- "Crybaby"? How about a character who is pushed into journeying by her parents, or pressured into it by her friends but is actually very afraid of what the journey will entail?
-Your "Jock" proposal sounds like it would fit into more of a "rich boy" character, one whose life is dictated by parental concerns. However, we already have a character like that, and that's dear little James.
- Your Manipulator seems more like a Swindler, and is more a character that would reslove his issues in one to three episodes. The Swindler Reform plot is a very easy one.
What I see here is that you're proposing a lot of Reformation plotlines. While a decent device, it's not one that can be used very often without getting extremely stale. And your ideas don't see a lot of actual development; the only change is the characters transitioning from "evil" to "good" rather than expanding and being fleshed out due to experience and relationship dynamics. Such characters may not be "gag" characters, but are certainly rather flat.
Honey, I'm not contesting that the BW and Decolora fell very short of the mark. You need to listen to what I am saying, because never have I praised BW for its character development. You need to stop accusing and start understanding, because you are very rude and make an appalling argument when you don't listen. Did you understand any of what I explained to you in the previous VM regarding adventure? I assume not, because you continue to argue as if you comprehend absolutely nothing.
In regards to your accentuation, a well-formatted post with decently explained points works far better than bolding every other line as a form of communication.
"Traumatic" is a much heavier word than you seem to be using it as. "Psychological trauma is a type of damage to the psyche that occurs as a result of a severely distressing event." Characters that you have mentioned have a difficult, dramatic, and life-changing past, but traumatic? Not really. Dramatic pasts can be good if done well, but really Pokémon is about growth and change over the course of the saga rather than mysteries of times gone by. While pasts could/may factor into characters and their development during the series, it is often not the major focus of the character. There are exceptions of course, both those done well and those not done well. And backstories ain't worth jack if they're badly written. So what we should be wanting for new sagas is for things to be well-written, no matter that they are.
