If it’s intentional, I guess Ultima being an Esper is the reason it slipped by me all this time.
I would say them being in the same location was just a coincidence.
I already knew about both their origins.
I know, but again, it doesn’t affect the story, as it’s never mentioned nor is there any cutscene with dialogue when you fight it. And to someone who hasn’t played tactics, Ultima would just seem like a really hidden and tough Esper. It’s also as hidden to the average non-completionist as any "Ultima Weapon" would be. And don’t forget, Ultima Weapon in VII was sort of canon to the story, though optional and rather tough, and Ruby and Emerald are just random super-bosses which pass for Omega.
So, while Ultima serves as Ivalice canon, at the same time it serves as FF tradition, ne? They’ve done dual-meanings before.
hah, and they weren’t even bosses in X-2, just encounters that aren’t even close to tough. They weren’t even in the same location either, Ultima was found in the Chocobo dungeon and Omega is found in the Farplane Glen. If you’re thinking of Via Infinito, all enemies are there.
They’re connected in terms of the fact that these "names" are a reoccurrance in the FF series – beyond that, there’s no connection in my opinion.
Ultima is the final "Lucavi" from FFTactics, set in the same world of Ivalice as FFXII, and the Omega in this game is simply an additional boss.
