Every character, new and returning, have at least three looks in Dissidia 012[duodecim]: Final Fantasy. Lightning’s third form is based on a soldier design from Nao Ikeda who created character art for Final Fantasy XIII and later Mana series titles such as Children of Mana.
Although it’s been leaked, Square Enix isn’t quite ready to reveal Yuna’s third form. Instead, they released screenshots of her another form, which is based on artwork from Yoshitaka Amano.
While the picture below is also based on Amano’s artwork, it is not Tifa’s third form. All first run copies of Dissidia 012[duodecim]: Final Fantasy in Japan come with a code to download this outfit from the PlayStation Store.
