In the final battle they say.
If you want to ignore evidence presented in the game, fine. I can do the same thing. Kuja never destroyed a planet.As for Ultimecia...that scan makes no sense. She is mixing past, present and future together through Time Compression. No one ever says she is absorbing anything. And also thery never say universe or existence in any of the dialogue. They just say "world" ie. the planet. No one brings up the universe or all of existence at all. Just their world.
Ultimecia absorb Kuja, Kefka, Sephiroth, etc. with all the rest of the universe.And if we're talking fights...Ultimecia dies hard.
