Well, in MHDos, the final offline boss is Lunastra (which takes 3 different quests to kill her the first time, the First in Volcano, the Second in the Desert, and the last in the Tower, respectively), and the Last Online Boss is Yamatsukami (Epic Battle, the MHFU Yama is... boring), the 3 Fatalis are just Challenges.
