Did you know that there’s an unused sprite for Hahn in PSIV? It’s a spell-casting graphic using two hands, like the graphic for Gryz’s War Cry and many of Raja’s skills.

I found this out myself when messing around with the PSIV disassembly almost a year ago, but have seen it before, as it’s included in the hell mode and purgatory version of the game.
Pretty interesting, I wonder if they intended to give Hahn another skill at some stage?
