That's quite a block of text you have there. Might want to break it up a bit; it was hard to read.
Anyway, I'm not sure how to respond to this, as it seemed more venting than anything.
Personally, I'm sick of the overdone shonen genre in its entirety. Characters - especially the Main Character - in shonen action series tend to follow a single formula:
*Start out somewhat weak, with a good trick or two
*powerful enemy arrives
*MainChar trains or seeks out the artifact to defeat said enemy
*MainChar encounters and defeats the enemy (and his lackeys, where applicable)
*Next story arc begins, cycle starts anew.
Worse, the series that initially don't follow this formula inevitably end up conforming to the status quo (I'm looking at you, Kishimoto Masashi!).
Now, I understand that encountering newer and stronger opponents is part of the deal, but honestly, can't I have a few noteworthy series that do it with style and originality? Or at least ones that fake it really well? I'm tired of Dragonball clones!
There's gotta be more than Bleach. Seriously.
Anyway.
The most of what you're saying, rathimal, seems to stem from the Young Author Problem. That being, when a young kid (usually in his early teens, seldom later than high school) sees such a shonen fighting anime/manga/videogame series, they instantly go into Fanboy Mode. When they start writing fanfiction about it, they tend to give the Main Character all sorts of benefits or powerups without giving the proper level of thought to how this would affect the rest of the series.
I think that, in most cases, they just haven't realized how boring it is to have a hero who can beat any enemy without much effort.
This isn't a new thing; take Superman comics, for example. When your hero is damn near invincible, it's hard to portray any conflict with tension, and tension is what keeps the audience interested. SO, they ended up introducing dozens upon dozens of doo-dads and villainous powers involving Kryptonite, and eventually killed Supes off. When they eventually brought him back, they wasted no time in giving him new weaknesses or loopholes through his invincibility, simply because they wanted to make his life-or-death struggles believably life-or-death.
For another example, look at damn near any console RPG (and even some tabletop RPGs, if the DM doesn't manage it well). Many of them have a large element of mindless power-levelling involved. When you get right down to it, after you've beaten all the toughest enemies, and you've taken your characters' levels to the maximum, and you've gotten all the most powerful items... then what? Where do you go from there if the game design didn't make the road to that end fun enough? Answer: Nowhere. The game fails hard. And fanfiction written this way fails hard for the same reasons.
Make Naruto uber-powerful? Better happen later in the timeline; "enfant terrible" isn't a role that suits Naruto. Stick an achiever!Naruto on the same team as Sasuke? Not unless Sasuke is the dead-last.
...actually, someone should write one like that. Turnabout is fair play. :lol:
