Fiend ( Final Fantasy VI ) Fiend , also known as Doom , is a boss in " Final Fantasy VI " . It is a member of the Warring Triad , and one of the three final bosses in Kefka ' s Tower before facing Kefka himself . Fiend has the highest HP of any enemy in the original game , and the third - most HP in the Game Boy Advance and subsequent remakes behind Kaiser Dragon and Omega Weapon . According to the " Final Fantasy III Nintendo Player ' s Guide " , the final battle sequence against the Statue of the Gods is supposed to be a rematch of the Warring Triad ; the third tier being Fiend . No official material supports this , however ; the idea was created by Nintendo of America . Battle . Fiend attacks in two phases . Its first phase consists of it using Blizzaga , Absolute Zero and Northern Cross , which can be avoided by equipping the proper equipment . Northern Cross can inflict Frozen but it has a low hit rate , and Ice protection combined with high M . Block stops it . When Fiend is damaged eight times during any part of the battle , it will use Reverse Polarity to switch the row s of the party . When Fiend is down to just over half its HP , it switches to a new strategy . A message will say " Fiend ' s aura is trembling violently ! " and it will gain Reflect , Haste , and Image , making it difficult to hit . Fiend will either use normal attacks or " Targeting " , picking a character for its powerful special attack called Fiendish Rage . Fiend will regularly cast Force Field , picking a random element and negating all damage done to it by that element . Locke can steal a second Safety Bit from Fiend . Strategy . During these first two phases , Holy spells work well , as Fiend is weak to the Holy element . Fiend has fairly strong Magic Defense , so Flare , Ultima , and Strago ' s Grand Delta are effective . If the player brings Strago Rippler can steal Fiend ' s status buffs . Force Field is Strago ' s final Lore , and Fiend is the only enemy to use it . For Fiend ' s second phase , attacks that cannot miss — like Tools , Bushido and Blitz — can pierce Fiend ' s Image , and Ultima will bypass Reflect . Casting Protect on the character that Fiend uses " Targeting " on will help them survive . AI script .

" Final Fantasy XIV " . Known as " Sephirot the Fiend " , he is one of the Warring Triad , three primal s that were defeated by the Allagan Empire and imprisoned as statues for centuries within the floating continent of Azys Lla . He is said to be the primal once worshiped by tree - like race who summoned him to defend them from an invasion from the Allagan Empire . During the later events of " " , his seal begins to weaken and the Warrior of Light must fight him within the depths of Containment Bay S1T7 . Etymology . In the original concept artwork by Tetsuya Nomura , the Warring Triad are given names beyond their basic titles . Fiend was given the name Sefilos , which translated as " Sephiroth . " The variation in English names is , much like " Demon , " a result of mild ambiguity in the Japanese god - title used for this entity ; specifically , まじん , " majin " , or 魔神 . It literally it means " evil god , " with a note that 神 ( " shin " or " kami " ) covers a wider variety of deific or supernatural entities than the word " god " may denote in English . " Majin " are nearly always malevolent , or at least " ill - omened , " with the possibility for disaster always laced in mortal interactions with them . Because of the varied nature of such beings in Japanese mythology and culture there has historically been disagreement over the best single term to use as a translation . " Devil " is sometimes used ( although classical Western devils of Hell are referred to as 悪魔 , " akuma " ) , as is " genie " or simply " evil spirit . " " Doom " seems to have been an attempt by translator Ted Woolsey to capture the idea of 魔 , specifically , with a little additional flair ; " Fiend " is another general term for evil beings but without some of the very specific imagery attached to " devil " or " demon , " and is generally a good match for " majin " in terms of imagery invoked .
