BEHEMOTH

[Netherblade]

Sorry guys.. they had a Behemoth in, but i killed it during Beta, and now I use it as a trophy in my Mog House

But i think it'll come back to Eorzea

i hope they bring back the ff12 style behemoths myself. Those were one of my favorites in looks. (the regular behemoths, not that reskinned dragon cop out king behemoth!)

Barring that, the traditional looking behemoths like in FFVI and FFX are nice too. FFXI ones had too many knobby bones and protrusions that made it look a bit awkward.
