One of my favorite FF staples.
1. Which game do you think they looked the coolest?
2. Which game had the hardest version?
For #1, I have always adored FFX Behemoths. They're the first one I always think of.
I guess I prefer the on two legs approach.
I dunno about #2... Probably FFXIII. They're the ones with the swords that operate as a separate enemy or target onto themselves, right? I remember there was one of them, named Tyrant, in that godawful tower on Pulse. I just could not beat that thing.
If that wasn't a Behemoth then disregard.
