Hi.
I think the number 99,999 comes from the official
website of ffx on
www.squaresoft.com, but I think
it's wrong. However, I did kill Omega weapon under
a minute. I just used Anima which has 255 (max)
strength. I think I used 5 of anima's physical
attacks and then its overdrive to kill omega
weapon. To be honest, I reckon you can take out
omega weapon just with anima's overdrive coz the
overdrive does more than 1 million HP damages.
The only think I didn't do well in that battle was
that I forgot to steal anything from him.
