Who is the "Top Dog" ?

I forgot something crucial about Tidus. If we are talking in terms of the power we see them in game then I forgot you can break the 9999 cap in FFX, so a totally pimped out Tidus would wipe the floor with all three of them combined. Oh my...coming from someone that dislikes Tidus that makes me cringe. In terms of just imagining this and that, and forgetting the base damage we see in game then I guess it's a matter of opinion and favorite character though.

X is the only one of these games that can break the 9999 standard I think.

Oh sure if you want to go that way nobody can take on Tidus. Then again, if you do go that way, you can also say that a truly maxed out Cloud probably has multiple Sneak-Attack + Knights of the Round combos in his equipment and even a single KotR would already knock out Tidus.

There's also the fact that Squall is the only one who can make himself Invincible, by using a Holy War.

Nah, there's not much point in going that way.

Edit: I still maintain that Lion Heart > Omnislash.
