Well you can stop imagining so hard, because if there ever were an 8-Bit Theater animated series (anime style of course), it might look like this:
And I’ve also included a montage of the characters which can quite nicely fit as a ‘stretched’ wallpaper, wihtout much distortion.
Since I could only fit in 6 of the 7, I did one with all the characters; one with Black Mage: Hell King instead of Black Mage; and one with Garland replace by Black Mage: Hell King. Click to get the full sized. Enjoy!
