what? they both have magic powers, both disguise themselves as elderly characters as Jafar disguises himself as an old man and Red disguises himself as an elderly dog in order to trick the protagonist, both have greedy henchmen (Jafar, Iago and Red, Carface who said that when they got the Horn of Gabriel they could open any casino or bank safe in the world), both are hegemonic and megamaniacal and in the climax both turn into giant monsters. They also both have the same body structure. so i figured if they teamed up they be unstoppable!
