In all FF series, what boss have the most cool look, in your opinion? And i'm talking about ALL the bosses. Monsters, robots, humans, demons, gods, random bosses, bosses that have a meaning in the story, secret bosses, summons, etc.

But this is only about the bosses. For example, Sephiroth with his black clothes don't count, because we never fight him using it. Some summons count, because they are bosses in some games, but the summons that aren't bosses, don't count.

So, your opinions?
