Dissidia 012 will tell the story of the twelfth cycle of battle between the warriors of the gods. According to Siliconera, the game will feature something like the Destiny Odysseys, only they will include Chaos characters as well. During the war, a few of the characters from the previous game were on separate sides, as Terra, Cloud, and Tidus worked for Chaos, Jecht was on the side of Cosmos. The game's main focus is on the new characters and explaining what happened to them, and why they didn't appear in the thirteenth cycle shown in Dissidia.

So I knew about Tidus but Cloud and Terra too? I pulled this from the the Dissidia wiki. I mean I can reason some of it out...if anything though this game is slowly attracting me to pick it up. Man it'll be like sixty bucks!
