Hardest "Weapon" Ever...

[Ultima Shadow]

chaos: I have to agree with Ultima on every single aspect, as always when it comes to this subject!

Rubedo: Ruby and Emerald both had strategies to make them very vulnerable. For Ruby, have KOTR and have the "absorb" Materia attached to them, so when you attack, and Ruby counters with Ultima, you still live (Or at least something to that extent)

Trowa: Through my first play, when I didn't level up all the way, I found Omega harder, simply because of Terra Break and some of his other killer moves. Afterwards, also after a ton of junctioning, and mass leveling up at the Island Closest to Hell, Ultima turned into a pain in the ass. *Sits and stares and sits and stares*

Yes, thanks to HP absorb and KotR you could take them both out with ease...

It actually was the same for me on my first plays... and then suddenly... I found out how usefull the "Defend" command really was. And Omega became an ant even without all the cheap tricks some people use.

ive went through ff7 again but this time Emerald weapon. Ultimate was easy as pie i learned shadow flare from him even though it missed

Well, Atma, Emerald, Ruby, Ultima (VIII), and Omega are all relatively easy. Omega from FFV was somewhat of a challenge, but that raises the question of whether or not it's actually a Weapon. I'll say that it is, simply so I can answer the question.

I'm surprised no one has tried to suggest one of the "false rumor" Weapons in FFVII, and I am profoundly thankful for that.

Atma sorta has to be easy, so you can like. . . keep playing the game?

[Masamune·1600]

Well, there were actually two Atmas in FFVI. The second one didn't have "Weapon" as part of its title, but it was a palette swap of the original. You can finish the game without fighting that particular Atma, although it's not very difficult.
