Your Dream FFXIV Boss fight

[R-Kine]

Maat from FFXI

[Suirieko]

This thing:

[Syn-X]

The rest of the WEAPONs (Emerald, Ruby, Diamond, and Omega).

[Redempt]

Anyone?

[Lisotte]

Promathia! Let's fight back the emptiness or whatever they called it!

Oh, actually cooler would be intervening in an Alexander vs Odin fight, like near the end of ToAU.

[Jin-]

Penance FF X. Was only in EU/JP version if i remember right

[MisterLucie]

The Lucavi would be the bosses leading up to her, obviously.

[ChazNatlo]

My Goodness, I can't believe I didn't think of this sooner.

Whichever expansion brings you to Alamigo. As a part of the story, you fight the former leader of the Corpse Brigade, on your own. This fight opens up a Trail where now you get to fight him four or eight on one, as opposed to just one on one. At the start of the fight, This man pulls an Iceheart and embodies a Primal. But he doesn't just embody ANY Primal, he embodies an Elder Primal, Belias.

Ladies and Gentlemen, Wiegraf Folles.

This (or Soken's version of it) would have to play after the transformation.

Braska's Final Aeon

Gods... what a badass.
In comparison, the light party trials are not as epic...
