I think Malefor simply got power-hungry. He was the rare purple dragon.
And when he knew that Spyro came as the new Purple Dragon, Malefor
got in some sort of "there's not room in this world for the both of us" kind
of mood. So Malefor pretty much has anger management issues.

Take dead rising, if everyone had stayed sane and worked togeather the zombies would never of entered the West side of the mall..But no we had to have people go insane, cry or run away from the terror of events..the crazed people were a majority of the game's bosses.

Malefor is pretty much the most bendable character for a fan-fiction, He pretty much has no reason for wanting to kill the world or destroy it, anyone could mend it in the story as he got corrupted and thought everyone was evil but himself.

The story i am working on is basically taking the emotional side of someone and snapping it, you then got a psycho infested creature on the loose going on a happy go Slashing vigilante spree..and for people who he thinks are pure of heart..it's doesn't get any better but getting lock in cages like animals

Well, that's me being my not-so-usual optimistic self.

But I digress. I'm a fanfiction writer myself. And I know I'm not a master, but then, writing is almost impossible to master as there is always something to learn, and different writing styles. So long as I like my work, I'm content. I've gotten positive feedback on it, but I don't let it go to my head. I just write because I love to write.

It also helps that I'm an English major, I suppose. 

What you might be looking for in this case is something that takes the tired cliches of LoS and gives them actual life. The only writer I can think of who actually did that with LoS material was ScarabDynasty, and she didn't need any tacked-on OCs to do it.

99% of fanflich SUCKs IMO only 1% is good i think.

yeah...

And how much of that 1% is actually taken from TLoS that already sucks as a storyline.  The best fan fiction isn't just good, it would require it to introduce completely different characters, instead of the ones that are in the story we think is crap.  Show me a good fan fiction that has 100% original characters and themes.  It may not exist...

...Star Wars wasn't based on a book. (Before you say anything, I've read Joseph Campbell's book and it has nothing to do with Star Wars.) I'm thoroughly confused now.

Note how I wrote "books and movies"

I've always been of the opinion that they wasted their money paying celebrity actors for those games. They should've paid for pro voice actors (who cost a lot less and do a much better job) and paid for some real writers (who, y'know, know how to write things).

Fun fact: LoS wasn't written by professional writers. The producers (aka, the guys whose job it is to raise money for the games and get them made) did the writing. It shows, too.

Oh, so they spend most of their budget on actors, and had nothing left for a writer.  Maybe the rare one-in-a-million good fanwriter could have done better.  Maybe if it was more accurate to the books and movies (Harry Potter, Star Wars, and Lord of the Rings) it would have been more original.
