Enh. A parody is only funny for a very limited amount of time, unless it's fed new material. As far as I can tell, DBZ was a parody for maybe a volume or three, after which it was milking a dead cow for more money because the fanbase wanted more of 'more power'.
That said, going back to the original topic (sort of), I've been told that the light novel version of Saito is a bit more likable, and considerably more awesome.
I've also found that fanfiction is more common the more one dimensional/stereotyped the main character is, as it means that more novice writers are more comfortable/reasonably sure that they can at least approximate how they're supposed to act (Which also explains the SI phenomenon to a certain degree as well.)
