Actually the Omega Weapon is just a sub-mission boss, you beat them. You level up and get something good. I think the best Ultimate Weapon I will ever fought is the "Ultimate Weapon" in Final Fantasy 7. You have to beat him twice, baby. After you beat him, you get an "Ultimate Weapon" for Cloud, and you can access to the mountain and get the Summon Monster- "Typhoon".
