Going back through the series, one of the more overlooked but amusing traditions in the series has been the FF series taking former bosses and high profile enemies, and making them into summons. Titan, Siren, Typhon, Bomb, Imp, Tonberry, Cauctar, Atmos, Magus Sisters, Yojimbo, and Gilgamesh. So in future FFs, what minor boss or memorable random enemy would you like to see get the Summon treatment in a future installment?
