Is it the difficulty? Is it the story? Is it the looks?
Tell me.

I think that good bosses should incorporate all aspects...

Difficulty goes to Seymour, the one on Gagazet. What gave him the power to mutate though? No reasoning. So he sux in the background area.(In that form)
He does look cool, but what was the reasoning behind his looks?

Story goes to Vayne. Nice full background around him. But in difficulty? I died once against him... Not hard at all. His looks are alright, but why a dragon who doesn't have as much power as he did, changing into that form?

Looks go to the non-cannical beasts, like Omega from FFX, or yazmat from FF12
Almost no story behind them, just enough to explain their existence. They have difficulty though...


I do not know of a boss that incorporates all of them...
