In heaven's name, stop saying that RD isn't a canon source for Chron knowledge. It's the same world, with the same rules and the same locals. Everything that happaned after Zeal's fall is exactly the same is it is in CT and in CC, because like Lucca said, the real changes began with Zeal's fall. Anything before that happaned the same way in the Lavos, Keystone 1 and Keystone 2 timelines. That means the FF was there already, in all three of those timelines. Schala was the source of the problems, because the Flame woulden't react without her. Had she decided not to activate the Machine, Zeal would not of fallen. Schala felt guilty in Cross' history, too: The one difference is she never got a chance to reincarnate completly as Kid. Only a part of her did. That part is CC's Kid, and when you free Schala she reached some kind of enlightment, so she dosen't feel guilty anymore.
Oh, and Lynx's japanese name is Yamaneko. It means Copycat (Or so I've heard), which makes no sense in RD, but unless I'm terribly mistaken, he was called Yamaneko in the Japanese version, too... So, yeah. Maybe they called him Copycat because he copies a cat, not because he's a cat who's copying someone else. His face did seem a bit feline to me, but other then that he's very swift and agile, as well as deadly and cunning. The perfect hunter, if you will.
