Mine was
Cloud lvl 99
Barret lvl 90
Cid lvl 94

I also decided to do that KotR thing to increase his hp by 200,000hp plus with one lvl 99 character and the battle was so long and dramatic especially at the end. Cloud was dead, Barret was a frog, and Cid was almost dead from that Super Nova attack. I finished off the battle with Cid casting Ultima which added a little flavor to my ending.
