Which one is your favorite in the series?
I would have to go with Summoner. They are almost always over powered. Rather it be Bahamut in Final Fantasy III or Bomb in Final Fantasy IV or Leviathan in Final Fantasy V, Crusader in Final Fantasy VI, Knights of the Round in Final Fantasy VII, Eden in Final Fantasy VIII, Ark in Final Fantasy IX, Magnus Sisters from Final Fantasy X, and so on. They can support or deal massive status effects... (Hades/Doomtrain).
