Tin dog

After about a half dozen mid-boss fight I manged to get to the top of the broken tower and fight the super powerful being that resided there. Then I beat it in under 2 minutes with a standard relentless attack...

What really contrasts the boss battle was the optional mission the was unlocked after it. First I had to find a secret room and unlock the final section of elevator, then ride it from the top to the bottom in one go just to get the monster to show up. Then the monster would weaken the whole party on the first attack and kill them all with it's second attack. So I had to figure out a strategy to not only avoid getting weakend but to also stregthen the party while making the monster weaker, and then after that having to gradually chip away it's health points. Plus having to do it all fast enough to get a perfect score.

With that battle finished the party reaches it's destination of the village that Vanille and Fang came from, only to find it empty and slowly being over come with white crystal sand. While scouting around I came across Vanille's old robot dog/rabbit thing just as it stopped working after over 100 years of waiting (must be energizers). With a quick side mission to find parts Sazh manages to get it runnign again, and it gave a bunch of rare items and an achievement.
