Bah!!!
On a fanfiction-related note...UPDATE THE TRANSLATIONS FOR BEFORE CRISIS YOU STUPID GUNSHOT ROMANCE SITE!!!!! I need to get to the...er..."explosive" conclusion before I turn thirty! You've got five years!!!
Okay, all rage aside, that website's actually pretty kickass. Just taking too long to finish translating so I can work on my story more. I COULD pull a bullshit ending out of my ass, but that would be stupid.
Oh...fine...for my own amusement:

Aeris and Nanaki got all of the materia pieces and gave them to Elfe, who transformed into the summon beast. They killed it, and Elfe regained her memory enough to say goodbye to her father, who along with Shears, jumped off Gaia's Cliff. Rufus continued his Libertarian rule over Midgar, and everybody became an Objectivist, even though the philosopher Ayn Rand never existed in the FF7 universe. Lynx grew up to hate video games, and was subsequently disowned by her parents.
Aeris gave birth to a two-headed dragon, who became the president of chocobos. Keter grew up to be a feral man, living in the forests and eating beetles.
Yuffie married Shake and they had ten kids.
Fuhito had seen the error of his ways and decided to take up sewing. He and Don Corneo hooked up and adopted the children of all the Don's former prostitutes.
Oh, and everybody LOVED Aeris, despite her having flaws just like the other characters, because she also learned how to shoot a gun and outmatched Vincent, who ended up pregnant, giving birth to Sephiroth's half-sister Fernando.

Yeah...I'll wait for the research.
