After this part is completed, I'll make another thread for the lesser villains. But this topic is for the primary antagonists. We will decide who is the strongest, second strongest and so-forth. Use the most powerful incarnations of all characters.

Sin is the main bad guy of FFX. Not Seymour. Or rather, Yu Yevon is the main bad guy.

We're going by story. Not game mechanics.

So, rank them.
