Square Enix released a few new screenshots of Dissidia 012[duodecim]: Final Fantasy. One of them contains Aerith, an assist character you get if you purchase Dissidia Duodecim Prologus. One of Aerith’s abilities freezes an enemy in their tracks. Protection of the Stars (or Planet Protector, the limit break name – thanks Tommy!) appears to be the spell that grants temporary invincibility.
We also have third form designs for Final Fantasy II characters. Frioniel’s outfit is based on a Yoshitaka Amano illustration.
The Emperor’s third form is from the opening movie of the PlayStation remake, which was released in North America as Final Fantasy Origins.
