I, personally, cannot wait for Dissidia to come out. So, I was looking at the Final Fantasy Wiki Dissidia page and saw these awesome character artworks and had the idea to put them on a wallpaper...
...yeah I have a lot of time on my hands. Click 'Download' for a bigger size. Visit my Deviant page for the 'Villian' counterpart to this.
I put the characters in order by game. So, Characters (Left to right):
Warrior of Light (FFI), Firion (FFII), Onion Knight (FFIII), Cecil Harvey (FFIV), Bartz Klauser (FFV), Terra Branford (FFVI), Cloud Strife (FFVII), Squall Leonhart (FFVIII), Zidane Tribal (FFIX), Tidus (FFX), and Shantotto (FFXI).
