Fiend Arena The Fiend Arena is a battle arena located on board the " Celsius " , available in " " and the " HD Remaster " versions of " Final Fantasy X - 2 " . Features . The Fiend Arena can be accessed at any point during the game by talking to Shinra on the " Celsius " . In its menu , the player can capture fiends , watch their Fiend Tale progress , manage them and finally , fight in the arena . The arena features two modes : Tournament Cups and Battle Simulator . The former allows the Gullwings to participate in cups against different monster formations . The latter gives them a list to choose any formation they have encountered in the cups to fight at will . Losing a battle in the Fiend Arena , be it in the cups or the Battle Simulator , will not result in a Game Over , the player is simply returned to the Fiend Arena menu . The only exception to this is the Fiend Portal when faced for the first time . Completing the storyline of captured creatures can award the player with accessories or unlock new enemy formations in the tournaments . Tournament Cups . Tournaments are carried out in three - or four - round elimination . Depending on the cup , either 8 or 16 teams will be facing off against each other . After every match , no matter if the player wins or loses , they obtain a pod . If they already have 8 pods , they receive curative items instead . Standard Cup . Standard Cup is available from the very beginning . The monsters in this cup are not too tough , but they may overwhelm players that come here too early . The player will often end up facing off against the Amorphous Gel , accompanied by a Barbuta , a formation that can be somewhat difficult to defeat at low levels . Winning Standard Cup for the first time awards the player with the Psychic dressphere . Beating it three times awards the Intrepid Garment Grid and unlocks Standard Cup : Hard . Other rewards include X - Potion x4 , Ether x8 , Titanium Bangle or Silver Bracer . Standard Cup : Hard . Standard Cup : Hard is unlocked by beating Standard Cup three times . The monsters the Gullwings will face here are very different from the ones they faced in the first cup . An enemy that is frequently encountered is Rukh who is capable of petrifying characters with its basic attack . Also , the Dark Elemental often defeats its opponents . Winning Standard Cup : Hard once unlocks the Grand Cup . Rewards for beating this cup include several accessories that increase attributes by 20 or increase HP or MP by 60 % like the Power Wrist , Tarot Card , Defense Veil , Mythril Gloves , Mythril Bangle , Gold Bracer and Talisman . Grand Cup . Grand Cup is unlocked after beating Standard Cup : Hard a single time . The roster of enemies fought in this cup is largely identical to that of the Standard Cup : Hard . However , as the name states , this is a " large " cup , meaning the winner is decided through a four - round elimination system rather than three . The first time the player wins this cup , they are awarded the Festivalist dressphere . After beating the cup three times , Grand Cup : Hard is unlocked . For placing first in this cup , the player is rewarded with small amounts of high - quality curative items such as Elixir , Remedy , Mega - Potion or Mega Phoenix . Grand Cup : Hard . Grand Cup : Hard is unlocked by beating Grand Cup three times . At first , the monsters fought in this tournament are similar to the Large Cup ' s , but several strong formations are added to its roster as the player completes the storyline of specific creatures or by simply beating the cup a couple of times . Beating the cup awards the player with the Abominable Garment Grid . During the first attempt , the final opponent will be a Chocobo . Winning the tournament unlocks the Chocobo Cup . After beating this cup three times , multiple dangerous formations are added to block early access to the Youth League Tournament . The player is guaranteed to encounter one or both of the following two " stonewall " participants every time following their third victory : Tonberry the Ripper ( Mega Tonberry ) and / or Shady Duo ( Black Elemental + Mushroom Cloud ) . These enemies are very strong and can wipe out most parties . At this point , the player is generally forced to wait until Ch . 5 when stronger fiends become available for capture after making progress in Via Infinito , or until the Mascot dressphere is obtained . When completing the cup for the fourth time , the last team the player faces will be two Cactuars and beating them unlocks the Cactuar Cup . Finally , beating the cup six times unlocks the Youth League Tournament . Subsequent wins can award Tetra Gloves , Tetra Guards , Black Rings , and Megalixirs . Chocobo Cup . Chocobo Cup is unlocked after beating Grand Cup : Hard once . The player can only participate in this cup if they have a Chocobo in their active battling party . Chocobos can be captured by setting up S - pods either in Luca , on the Mi ' ihen Highroad or the Calm Lands . In this cup , players have to face off against enemy teams that always include a Chocobo . They are paired up with strong enemies like the Anything Eater . Winning it awards the player useful accessories like Regal Crown , Champion Belt , Rabite ' s Foot or Minerva ' s Plate . Cactuar Cup . Cactuar Cup is unlocked by beating Grand Cup : Hard four times . The player must have a Cactuar in their party to enter . Cactuars can only be captured in Chapter 5 after unlocking the Cactuar Hollow by setting up an S - pod in Bikanel . Just like in the Chocobo Cup , enemy teams always include a Cactuar . Most monsters they are paired up with are giant fiends from the Cactuar Dungeon . At times , they will also fight the Jumbo Cactuar and unlike in the dungeon or the Via Infinito , he will actually attack the party here . Winning this cup awards the player accessories that greatly increase attributes like Power Gloves , Crystal Gloves , Oath Veil or Pixie Dust . Youth League Tournament . Youth League Tournament is unlocked by beating Grand Cup : Hard six times . In this cup , the player will fight various NPCs , including Lucil , Elma , Yaibal , Nooj , Gippal , Baralai , Lulu , Kimahri , Garik , accompanied by two Ronso Youth s and the duo of Brother and Buddy . Most enemies can appear either solo or in a team with some other enemies , for example Nooj , Gippal and Baralai will occasionally appear as a team . If the player completes the storyline of all six of Leblanc ' s Goons , they can also be fought here . As a reward for beating it for the first time , the player is awarded a copy of the Mascot dressphere . For subsequent victories , awards include accessories like Defense Bracer , Speed Bracer , Tetra Bracelet or Shmooth Shailing . Aeon Cup . Aeon Cup is unlocked by capturing and transforming eight specific creatures into aeons . In this cup , the player will exclusively battle aeons . Shiva , Anima , Yojimbo and the Magus Sisters are identical to their storyline counterparts . The others are much stronger here than they were during the mandatory fights . The most dangerous foe is Bahamut with over 100 , 000 HP and very dangerous attacks . Beating this cup awards the player with one of several stat - raising accessories . If the player manages to win three times , they obtain the Peerless Garment Grid , one of the best Garment Grids in the game . For subsequent victories , they can obtain Kaiser Knuckles , Crystal Ball , Crystal Bangle or Rune Bracer . Fiend Portal / Fiend World Cup . The Fiend Portal can only be unlocked through a sidequest involving the capturing and releasing of several specific creatures . After it is completed once , the name changes to Fiend World Cup . In the Fiend World Cup , the Gullwings face demonic enemies , including Doomstone s , Spellspinner s , and Imps . The deadly Mega Tonberry also frequently appears . Unlike other cups , the player ' s HP and MP are not restored after every round , so they must continue fighting with whatever they had left . It is a four - round elimination tournament instead of the usual three . When the player participates in the Fiend World Cup for the very first time , it is named the Fiend Portal , and the final opponent is Omega Weapon . Losing to any team results in a Game Over as the " Celsius " explodes . After winning , the player is given a choice to recruit either Ultima Weapon or Omega Weapon . Since Ultima Weapon was recruited to unlock the Fiend Portal in the first place , choosing Omega Weapon is recommended . If the player indeed chooses Omega Weapon , completing his Fiend Tale causes the creation of Almighty Shinra , who then hijacks the Fiend World Cup and turns it into Almighty Shinra ' s Cup . It is identical to the Fiend World Cup except that Almighty Shinra is always the final opponent and beating him gives the player an opportunity to recruit him . After beating Omega Weapon and Almighty Shinra , they occasionally appear in the Fiend World Cup . They usually beat any computer - controlled team they face , so the player will most likely have to fight them . Winning the Fiend World Cup awards the player with outstanding accessories . Possible rewards include the AP Egg , Soul of Thamasa , Adamantite and Gold Hairpin . Farplane Cup . Farplane Cup is the final and most difficult tournament of the Fiend Arena . It is unlocked by beating every other cup , other than the Almighty Shinra ' s Cup , at least once . In Farplane Cup , the Gullwings face the game ' s most powerful enemies and superboss es , including the Black Elemental and Mushroom Cloud combo , Concherer , Elder Drake , Insect Matriarch , Azi Dahaka , Paragon , Trema , and Major Numerus . Trema usually defeats any team he faces and therefore has to be fought almost every time . At times , the player may also encounter characters from " Final Fantasy X " : Tidus , Auron and Seymour . If these characters are beaten during the cup and the Gullwings win the cup afterwards , they are given the choice to recruit them . If they choose to recruit them and then release them later , Seymour and Auron can be re - recruited . Releasing Tidus , however , prevents him from ever being recruited again . The most dangerous foe in this tournament is Major Numerus , the strongest superboss of the game and unique to the Farplane Cup . He only shows up after the player has already beaten the cup multiple times and if he appears , the player has a high chance of fighting him — although it is possible that he loses to enemies like Trema or Paragon . It is also possible for Major Numerus to lose to the Elder Drake , although this is a rare occurrence . Winning the Farplane Cup awards the player with one of the rarest and most valuable accessories in the game . The possible rewards are : Ragnarok , Force of Nature , Key to Success , and Iron Duke . Participating in the Farplane Cup and defeating Major Numerus through the battle simulator are the only ways to obtain multiple Iron Dukes in one playthrough . Battle Simulator . The Battle Simulator allows one to fight the fiends they have encountered through the various tournaments . Note that dying in these battles does not result in a Game Over , and various strong enemies can be repeatedly fought ( such as Concherer , Paragon , Trema etc . ) for their drops ( e . g . Dark Matter ) . Some teams can only be encountered by observing a fiend ' s Fiend Tale . See the Creature Creator article to see where to capture the corresponding fiends . Most of the fiends encountered in the Fiend Arena , when Oversouled , count towards Shinra ' s Bestiary , allowing the Battle Simulator to be a helpful tool to cause a fiend to Oversoul ( see the Oversouled article for specifics ) . However , if a fiend has different abilities than the version encountered in the main story , then it will not count towards Shinra ' s Bestiary but can be repeatedly fought to bring about an Oversouled version which can then be fought in the main story . Page 6 . Note : Cactuars all teach the Blue Bullet ability 1000 Needles . Quests . Several sidequests are tied to the Fiend Arena and completing them often offers great rewards . Sphere Break Elites . By completing the storyline of Varan , the player unlocks the Besaid Aurochs ' locker room in Luca . Here , they can face the three best Sphere Break players in the game with Quota values upwards of 500 . Defeating the elites will award the player some rare accessories — Enterprise , Invincible , and Ragnarok , respectively . Machina Panzer . If the player captures and completes the Fiend Tale for Killer Hound , who can be captured by setting up an S - pod in Bikanel , they are instructed to look for a machina in the Zanarkand Ruins . Now they can capture the YSLS - Zero there by using an M - pod . Completing its storyline activates a mission . The player is told to look for a 1000 - year - old machina . That machina is the Machina Panzer , found by setting up an L - pod in the Thunder Plains . Completing the Fiend Tale for Machina Panzer awards the player with the Adamantite accessory . Aeon Cup . To unlock Aeon Cup , the player must find and transform several fiends . The fiends can be transformed by increasing their Story Levels by 4 after capturing and then releasing them . Doing so will release one of the eight aeons and unlock them in the Battle Simulator . If the player finds all of them , Aeon Cup is unlocked . If the player manages to unlock the cup and then beat it three times , they obtain the Peerless Garment Grid . Fiend World Cup and Almighty Shinra . Unlocking the Fiend World Cup is quite complicated . The sidequest can only be started after Chapter 2 and completed in Chapter 5 . The Fiend Tales of many creatures must be completed in succession . All these creatures receive a Fiend Tale Complete at Story Level 3 except for Ultima Weapon and Almighty Shinra . Musical themes . During the Aeon Cup , the aeon battle theme titled " Aeons " plays instead of the normal tournament music . During the Fiend World Cup , the typical tournament theme is substituted with " Clash " . During Farplane Cup , " Demise " plays instead of the regular tournament theme .
