The Omega [Weapon?] - Pure Speculation?

[Zohar_Lahar]

Omega itself was a weapon like Ultima but while Ultima was to pacify primals such as titan and Garuda in level, Omega was designed to take down Bahamut if they ever lost control of the Elder Primal. Needless to say its power is very attractive to many.

The question is, was it to counter Bahamut the Primal, or Bahamut the First Brood? The latter adds a lot of implications for the plot of Heavensward.

I would say Bahamut, the Primal.The real question here is that if Omega's fuctional workings is only if Bahamut Primal is present? Or Can acctualy be used for different battle purposes?

Bahamut of the First Brood was long dead when Allag invaded Meracydia. The Meracydians summoned him from the grave to defend their nation when the Allagans started to overwhelm them. Omega was used to defeat and restrain Bahamut so that he could be imprisoned in Dalamud. Given that Bahamut the primal is supposedly far more powerful than the original though it would be safe to assume that Omega would easily overwhelm Midgradsormr's children.

Having said that we don't know how much more powerful the dragon kings may have gotten in the millenia since then. We do know that Omega is confirmed to have a role in the 3.0 story though so there'll definitely be something there.
