So while listening to the OST piece of the Karna Masta fight in Menon (Despair and Hope), I like to think of the fight going something like a boss fight in like Ocarina of Time, Majora's Mask, and the Dark Souls games. Wherein you, the character is going up against a giant enemy, like Ganon in LoZ, or pretty much an Dark Souls boss with this epic music in the background, and you (The Hero) somehow against impossible odds, have managed to get as far as you have, defeated Gods, Demons, and powerful foes. Are now facing the most powerful god, Karna Masta, with little hope of winning, yet have all the backing you do, end up, against all odds, won, and walked away being the one that defeated the Emperor of all the gods, with this f*cking EPIC sounding music in the background to accompany you in this fight to the finish (obligatory PMD T/D/S final boss reference)

So in short, I like to imagine the Holy Emperor Karna Masta fights in 3D similar to those boss battles in other games
