Strongest Move on any FF game

I liked Cloud's OmniSlash if you get him to 99 with the Ultima Weapon. Just go upside someone with that o.O

Then there is the Lesser-OmniSlash (Squall's Renzokukenfallberjibslappination-attack) with the Lionhart(Leonhart?), and thats pretty good too, specially on da Final Ultemecia, Ultima Wep, Bahamut, and that mofo Omega Weapon, who killed me like 40 times.

If a MOVE is good, does DOOMSDAY or FLARE Sword from FF9 count? Those did WIKKED damage, just not on Necron =/

My favorite move is probobly gonna be OmniSlash. Gotta love the fast moves, and all that up in ur face-ness. But its always better at that one part when Cloud and Sephiroth go at it 1 v 1 and u get it right away, so its just a finish thing. Yeah, that was juicy.
