Characters that should be in Dissidia

[Wolf Kanno]

A goodly number of the villains aren't the end-all final villains of their games. The developers specifically chose villains who weren't end-game bosses to avoid the villains with little to no character development, like Zemus/Zeromus, Yu-Yevon, and the others in that same group. They also tried to go with characters who had attachments to the main characters, yet were still important to the plot.

They chose Cloud of Darkness over Xande

Xande is a bit of a non-entity, despite a more fleshed out back story he only sends lackeys to fight you and technically only encounters your party once. In regard's to CoD, she is the result of the balance of light and darkness being disturbed and as the Light Warriors are chosen by the crystals to restore this balance, I feel this ties them together much better than an "armchair villain" like Xande. Thematically, it works better. Course I'm hoping he'll appear in a sequel.
