Oh yeah. I went solo against Ruby Weapon with Cloud, because I went in without the warning to not attack when it's hands were in the ground. And still won. Though he had crazy materia combos. Like counter-attacking with Ultima. His final attack was either Pheonix or Life 3 or something. Can't remember. He could W-Summon Knights of the Round. And his Limit was Omni-slash and constantly being triggered. And I had 99 Elixers to keep me going. There really wasn't any way I could lose. So it's hardly a real accomplishment. But it felt nice at the time
