cross'o'ver / n. 1. Point or place of crossing. 2. Overlapping, esp. from one style or genre to another.


This page is dedicated to the miscellaneous crossovers that find themselves in several or all of the games in the series. Unlike commonalities that stay from game to game, like potions, white mages, summoned monsters, and Ultima Weapons, these crossovers are related to characters, settings and story, not gameplay. They have their own sections below. For corrections/additions, go here.

Music Crossovers

Almost every Final Fantasy, in some way, has three music themes in it.

  • Prelude: this was the first tune anyone ever heard when popping any Final Fantasy game into a console system. Its soaring melody has been ingrained in our thoughts. The NES preludes were only a single instrument; SNES and later versions had another line of music over the top after several bars without it. It's curiously absent in its entirety from FF8, although some of it plays during the "game over" music (The Loser) and in the ending. FF9's Crystal World is a remix. FF10 has an upbeat, disco arrangement. Tactics also only has a small variation on Prelude; it plays after winning a battle. MQ does not have Prelude in it. FF11 plays it when you first open the client and while you receive updates.
  • Final Fantasy: this song always appears in the introduction, the ending, or both. It does not appear in FF10, Tactics or MQ.
  • Victory Fanfare: This has remained more or less unchanged from FF1 through FF6. However, FF7, FF8, and FF10 only kept the first few trumpet bars after winning battles (FF7 had a subdued version of the full Victory Fanfare playing after winning a Chocobo Race). It was absent from MQ and Tactics.

    In addition, the battle themes from FF1 through FF6, as well as FF9, start with the same strain of music.

    Finally, the Chocobo Theme appears in some way in every numbered FF, starting with 2. Each game has a different version of the Chocobo theme, like Samba de Chocobo, Electric de Chocobo, etc. FF7 has four different Chocobo themes! (Fighting, riding, racing, and waltzing. O_o)

    The Logos

    Every Final Fantasy game in the numerical series has had the same main logo. In this logo, the title is always underlined in a high roman typeface in black on white, with the Japanese translation under the underline. There is also background image related to the game's plotline that has a washed-out, watercolor look, which obviously changes with each game. This logo has been the standard since FF4, but the re-releases of games on Game Boy Advance included revised logos with this motif. The logos for Mystic Quest, Crystal Chronicles, Legend of the Crystals, and Last Order have the same font but don't include a watercolor picture. The following games do not have the traditional logo: Before Crisis, Dirge of Cerberus, Crisis Core, FF: The Spirits Within, FF: Unlimited.


    FF1 - Garland or a light warrior

    FF2 - Emperor Paramekia

    FF3 - Knight job class

    FF4 - Kain

    FF5 - A Hiryuu/Dragon

    FF6 - Terra in Magitek Armor

    FF7 - Meteor

    FF8 - Rinoa and Squall embracing

    FF9 - The Crystal

    FF10 - Yuna performing The Sending

    FFX-2 - Yuna, Rikku, and Paine

    FF11 - A slew of playable characters

    FF12 - A Judge

    FF12: Revenant Wings - ???

    FF13 -

    FF13 Agito - ???

    FF13 Versus - ???

    FF: Tactics - Ramza and some playable characters

    FF: Tactics Advance - A Judge on a Chocobo

    NOTE: The logo for FFVII: Advent Children duplicates the FF7 logo, but it looks like a graphical mask over some sort of chemical diagram. This shape is a motif in the movie, showing up in a statue in Edge, and in Cloud's sword.

    The Moai

    In many games, Squaresoft tries to sneak in pictures of a stone stern-looking face. This face has been postulated to be the Moai, mysterious stone creations scattered all over Easter Island. However, the appearances of these faces is random, and without any meaning in the FF Universe.

    In 1976, the Viking 1 Orbiter, while taking pictures of possible landing sites for the Viking 2, came upon a Martian landform that looked remarkably like a face. Much speculation rose about this photo, ranging from being a natural mesa to being a monument by ancient extraterrestrials. For our purposes, this looks remarkably like the Final Fantasy Moai, compounded by the fact that its first appearance was on the moon in FF4.

    'Face on Mars' taken by Viking I; 7/25/76

    Later, hi-res pictures taken of the same site revealed the formation to actually have little resemblance to a human face. Most of the resemblance in the first photo is due to errors in the photography. It is, in fact, simply a mesa with a large rock formation in the middle. Thanks to Scavenger 382, webmaster of the RPG Compendium for pointing this out to us.

    FF4:
    The Moai on the moon.
    FF5:
    The Moai under the water.
    FF7:
    The Moai at great glacier.
    The Moai in the Chocobo Racing Arena.
    FF8:
    A huge number of invisible "stone faces" were part of the optional Obel Lake quest. Also, a UFO carries a Moai in the PuPu side quest, as seen in the picture.

    If you've found other Moai faces in FF games, send them to us.

    NOTE: The Moai is hardly an FF-only phenomenon. The original Moai are from Easter Island and show up all over the place. These appearances are definitely NOT references to Final Fantasy (the Moai face is quite possibly the most obscure FF in-reference there is). So unless it's extremely blatant (like the Secret of Mana instance mentioned in Ex-Crossovers) please do not send in any Moai crossovers.

    Weapon Crossovers

    EXCALIBUR
    Excalibur was named after the sword King Arthur pulled from the stone. In Final Fantasy, this is often the best weapon for a Knight or other Fighter-type class. It is two-handed, inflicts holy-elemental damage, and can either come through a side-quest or treasure chest, or normal progression. Usually, it's not too hard to encounter.

  • FF3 - A holy-elemental sword in a stone found after encountering Kunoichi. It says "Can you withstand my light?"
  • FF4 - Cecil's second-best weapon, holy-elemental. He receives this after giving Kokkol, the blacksmith dwarf, the Legend sword and Adamant.
  • FF5 - A holy-elemental sword.
  • FF6 - A holy-elemental sword.
  • FF8 - Wielded by Gilgamesh, his second-best attack
  • FF9 - A holy-elemental weapon for Steiner, and teaches Climhazzard. There is also an Excalibur II, even more powerful than the Ragnarok, if the player can reache Terrace in Memoria in twelve game hours. The description says "The ultimate sword, used by a legendary king. It was forged in another world."
  • FF10 - A sword which has the "Break Damage Limit" attribute
  • FF11 - A relic sword usable by the Red Mage or Paladin.
  • FF12 - One of Gilgamesh's swords.
  • FFT - Cidolfas joins your party with this sword.
  • FFTA - A knightsword sword that does holy damage. Also an Excalibur2.

    MASAMUNE
    Since FF1, there has been a weapon called the Masamune in every game. Normally, this would be listed in the weapon section, but the Masamune has played a number of different roles in games besides just being a weapon. It also plays a prominent role in Chrono Trigger, a Squaresoft game released around the time of FF6 and FF7.

  • FF1 - The best weapon, and unlike most others, this can be equipped by any class, including those that can't use swords.
  • FF2 - A powerful sword.
  • FF2 - A powerful sword.
  • FF4 - A powerful katana for Edge.
  • FF5 - One of the sealed weapons.
  • FF6 - Most powerful weapon for Cyan, which was renamed "Aura" in NA.
  • FF7 - Sephiroth's weapon of choice.
  • FF8 - One of Gilgamesh's weapons that delivers massive damage.
  • FF9 - One of Zidane's weapons, appearing as a double-bladed katana.
  • FF10 - Auron's celestial weapon.
  • FFX-2 - Although not named, Rikku's Dark Knight uses Auron's celestial weapon.
  • FFT - Wielded by Ninjas.
  • FFTA - Wielded by Assassins. Later in the game, the Masamune 100 shows up with the legend that it will not dull for one hundred years.
  • FFCC - An artifact that increases strength.

    EXCALIPOOR
    Unlike the Excalibur, which is often an exceptional two-handed sword, the Excalipoor is the exact opposite. It first premiered in FF5, when Gilgamesh, thinking he was using the Excalibur, used it (then named Excalipur), only to find it did minimal damage.

  • FF5 - A weapon of Gilgamesh used near the climax of the game, which delivers humorous results. Low attack power, but causes massive damage when thrown.
  • FF8 - One of Gilgamesh's four random attacks, this one only does one point of damage.
  • FF9 - One of Zidane's weapons.
  • FFT - An imitation of Excalibur, but noted for its fine craftmanship.

    SAVE THE QUEEN
    Typically used by paladins or noble characters. In Quistis' case, it was a chain whip, but it is usually in the form of a sword. In Kingdom Hearts and Kingdom Hearts II, Donald's weapon, a magic staff, is also called "Save the Queen". In addition, Goofy's best weapon, a shield, is called "Save the King".

  • FF8 - Quistis' best weapon.
  • FF9 - Beatrix's (only) weapon.
  • FF11 - A Paladin's sword that enhances the effect of Cover and grants accuracy bonuses.
  • FFT - A Knight's sword.
  • FFTA - A sword for Paladins.
  • FFCC - An artifact that increases strength.

    RAGNAROK
    Like Excalibur, this is a two-handed weapon that appears frequently in the series. It has no real special characteristics, only that it is extremely powerful and typically found at the end of the game. In FF8, Ragnarok was the name of the spaceship. In FF6, Ragnarok can also be used as a summon. Also it is the name of one of Sora's special attack/abilities in Kingdom Hearts.

  • FF3 - The best weapon, and unlike most others, this can be equipped by any class, including those that can't use swords.
  • FF4 - Cecil's best weapon, renamed "Crystal Sword" in FF4 EasyType NA.
  • FF5 - A weapon guarded by Shinryu.
  • FF6 - When obtaining this magicite, the user has a choice to make it a weapon or a summon. The weapon can cast Flare randomly.
  • FF7 - Cloud's second best sword, next to Ultima Weapon.
  • FF9 - Steiner's best weapon.
  • FFX-2 - An accessory that causes MP cost to be 0.
  • FF11 - A two-handed relic weapon for the Warrior, Paladin, or Knight.
  • FFT - An upgradeable knightsword.
  • FFTA - A regular sword. There is also a "Nagrarok" weapon that is much more powerful.

    Character Crossovers

    Several character names make appearances in many FFs.

    CID
    There's been a Cid in every Final Fantasy (excluding MQ) since FF2. These Cids are usually old, brilliant men who frequently control the airships and have high aptitudes for engineering. Cid was playable in FF4, FF7, and Tactics.
    FF2: Cid - The creator and owner of the world's only airship, the Dreadnought, lives in Poft. He gives rides for overblown charges. Much later in the game, after an attack by Paramecia's Whirlwind, he gives the airplane to the heroes with his last breath. FF3: Cid - The funny-looking engineer is the mastermind of airships on the Floating Continent. This overblown little man works for the king of Argass and utilizes the Time Gear to make airships. He was stuck in Kazus under the spell of Jinn (causing him to become a two-dimensional ghost), but was helped out by the Heroes.
    FF4: Cid - The mastermind behind Baron's Red Wings airship squadron, he's a crusty man, fairly old, who nevertheless has the work ethic of an entire anthill. He overworks himself several times throughout the game, risking his life, but he's tough as nails. He lives with his daughter in Baron Town. FF5: Cid Previa - A mechanical genius, Cid was the one who built Karnak's Fire Ship. Because the Crystal began to fail, they locked him up. Bartz (who was locked up in an adjacent cell) escaped with his help. Later, Cid and his grandson Mid (who followed in his footsteps) take up residence in a Ranka ruin called the Airship Base; they were the brains who got the Airship up and running.
    FF6: Cid - The brains behind the Magicite operation, he works wonders for the Empire before realizing just what they're planning on doing with it. After meeting Locke and the gang, he quits his day job and joins the Returners. He's known Celes since she was a child and sees her as a daughter or granddaughter. FF7: Cid Highwind - A rough, crusty middle-aged aviator. His dream was always to go into space, but thanks to a bit of extra spot-checking by his underling Shera, who put herself in danger to make sure the launch went through, he ended up scrapping the whole project. He never really forgave her. His technological prowess, like all Cids, is unmatched. He can pilot anything. He uses a spear in battle and he's never without a cigarette.
    FF8: Cid Kramer - He looks too nice to head a military academy, but there he is. He can be quite forceful when push comes to shove, but he's a bit of a coward. He started the orphanage with his wife Edea, but was forced to transform it into Garden when she was possessed by Ultimecia. Having to live with the fact that he might have to order his wife's death is not a nice feeling. When danger from Galbadia threatens, he runs. Since Garden becomes mobile later in the game, he could be considered to be in charge of an airship. FF9: Cid Fabool IX - The ruler of Lindblum and airship genius extraordinaire... well, he would be, except that his wife Hilda turned him into an oglop because he carried on an affair. An attempt at restoring him midway through the game just turns him into a frog. Shame, because he can't think well without his human brain. He's still an expert at Tetra Master, though. Dagger calls him "Uncle Cid".
    FF10: Cid - The leader of the Al Bhed is bald as a billiard ball and speaks like Yosemite Sam. He cares deeply for his niece Yuna and his daughter Rikku, and is fiercely protective of them. He's a whiz with machina, like all Al Bhed. Strong, cynical, and quite the hard-liner. In X-2, Cid finds it useful to parade the Zanarkand Ruins as a tourist attraction. Yuna gets annoyed by this and (if you like) tells him off. He spends most of the game sulking in the Thunder Plains, at which point he has to get rescued by his daughter and niece from a nasty monster. After this, he comes onboard the Celsius and makes a pain out of himself fighting with Brother et al. FF11: Cid - An engineering genius, and figured to be the smartest man in the world. He originally made his fortune from studying ancient Zilart technology and using it in his inventions. When he found a mysterious crystal in the Northlands, he sent the ill-fated mission there to see if there was more. This piece actually turned out to be a chunk of the Star of Tavnazia. Using the knowledge he gained from his studies, he developed a crystal engine that would eventually power airships. The Archduke of Jeuno commissioned him to build a fleet of airships to be used in the Crystal War, but only one was ever publicly used or needed.
    FF12: Doctor Cidolfus Demen Bunansa - This Dr. Cid is one of the main villains of the game. As usual, he is a technological genius, but here takes it way too far, largely deteriorating into insanity. Much of that is probably due to the influence of Venat, who is usually invisible. Tactics: Cidolfas Orlandu - Also known as "Thunder God Cid", he leads the Nanten Knights and has done so since the Fifty Year War. An extremely powerful swordsman who has mastered all of the available sword techniques. He was framed by Delita for Goltana's assassination and joins Ramza in his battle against Delita and the Church's Zodiac Braves.
    Tactics Advance: Cid Randell - Mewt's father in real life becomes the Judgemaster in Ivalice. It's just what he needs to perk his spirits up after his wife died, because back in the real world he cuts a pretty pathetic figure. However, his ethics are superb, and he goes as far as to cut himself off from the palace (and his "wife" and son) to ensure that no one is above the law. After finishing all 300 missions, Cid will join Marche to sock it to a bunch of renegade Judges. TSW: Professor Sid - The man who made bio-etheric energy possible, Sid is a gentle man dedicated to getting rid of the Phantoms with minimal possible damage to the Earth itself. He has a great fondness for his assistant Aki, and a respect for the pain she goes through. He is deeply insightful into many things in life, and is seldom wrong. When he is, though, he admits it genially without a shred of ego.
    Unlimited: Cid - This version's Cid is a cheerful, optimistic, and energetic technician, a wizard at anything electronic. He carries around weird high-tech equipment and inventions wherever he goes. He names his inventions after females and has a way-too-close connection with them. Dawn of Souls: Cid - Not really a character, but Cid is mentioned in GBA's FF 1 & 2: Dawn of Souls. After you learn to speak Lufenish, a man says a long time ago, a man named Cid built the airship.

    BIGGS & WEDGE
    Characters named Biggs and Wedge have been in 6, 7, 8, 10/X-2, 12 (where their names were anagrammed to Deweg and Gibbs), and TA, and also have cameo roles in Chrono Trigger, another Squaresoft game. See Star Wars Crossovers for more information.

    CHARACTER CROSSOVERS

  • Cloud from FF7 reappeared as a playable character in Tactics.
  • Aeris also appears there but is only called the Flower Girl.
  • Gilgamesh from FF5 reappeared as a summon in FF8. He also appears in a few places in FF9, where he's also called Alleyway Jack. He plays a prominent role in FF12.
  • Gogo appeared as a boss in FF5 and a playable character in FF6. Nevertheless, he is two different characters in these games who only have two things in common: their propensity to wear loud clothes, and their Mimic class. Perhaps they're distant cousins.
  • The Magus Sisters: Cindy, Mindy and Sandy from FF4 also appear as powerful summons in FF10/X-2. They also *may* make an uncredited appearance in FF9 - there are three statues in Alexandria (to the right of the ticket booth.) One's short, one's fat, the other tall and lithe. However, there's no actual proof that this is an intentional crossover. In TA, there are three lamias called Mindy, Cindy, and Sandy as well.

    CAMEO CROSSOVERS

  • Lone Wolf, the thief, is behind bars in both FF5 and FF6.
  • Boko the Chocobo, Bartz's buddy in FF5, is the Chicobo belonging to Squall in FF8, and rescued by Ramza and Agrias in Tactics. The Japanese "initials" (first syllables) of Bobby Corwen, the Chocobo in FF9, is "Boco". (sent by CSW Khan)
  • Hein, the sorcerer bad guy in FF3, has the same name as the "father of sorceresses" in FF8 in a completely different context. It just possibly may have another crossover in the form of General Hein from FF: The Spirits Within (they're pronounced the same).

    FF11 Crossovers

    FF12 Crossovers

    Other than the many references in the World of Ivalice, FF12 has some interesting ones:

    FF Tactics Crossovers

    There are many FF series crossovers in FF Tactics besides the obvious one of Cloud and Aeris, specifically in the Proposition section. Here's a list! The parentheses say what the crossover is, and which game it's from. U.L. stands for "Unexplored Land".

    Adamant (Monster, entire series)
    The Adamantaimai was found in the Proposition, "Terror Of Assault Cave".

    Anna (Character, 4)
    She and Gilbert write love letters to each other in "Letter To My Love" and "Joyous Song For You".

    Assault Door (Enemy, FF4)
    The Assault Door was found throughout the Sealed Cave in FF4; it was used extensively in "Minimum's Melancholy" Propositions.

    Bacchus' Wine (Item, throughout series)
    The wine is called "Vaccas Liquor" and is mentioned in the Proposition, "Battle! Demon Lylis!"

    Baron (Place, 4)
    In FFT, the Crystal Tower U.L. was supposedly part of Baron Castle. The Castle of Trials U.L. was purportedly Baron's military school, where the Red Wings (from 4) graduated.

    Blackjack (Transportation, 6)
    Setzer's ship is a casino ship in the "Wandering Gambler" Propositions. Setzer himself shows up.

    Calcobrena (from FF4)
    The Calcobrena were Luca's dolls which became possessed by Golbez and attacked Cecil. In FFT, the "Calcobrina" Treasure was just a doll.

    Chaos (Monster, 1)
    The Shrine of Chaos is a U.L.

    Chimera (Enemy, entire series)
    The Proposition "At The Hilltop Mansion" has an enemy named Kimera.

    Chocobo Forest (Place, 3, 4, 5, 6, 8)
    Adequately represented by the U.L. "Chocobo Forest".

    Corneria (Place, 1)
    A possible mention as the woman Cornelia, in the Proposition "Rescue of Cornelia".
    Dorga (from FF3)
    Has a ship named after him in the Proposition "Doga Salvage".
    Echo Plant (from FF5)
    There's a "Whisper Plant" found in "Destiny Of The Company". The Echo Plant was used by Zeza to communicate with Galuf in FF5. A similar device, the "Echoer" harp, was used in FF4.

    Elder Tree (from FF3)
    The tree used by Hyne to build his flying castle was rightly called Yggdrasil, the Life Tree (a term from Norse legend used in many RPGs). The "Parasite Tree" Treasure leeched off the "Yugudoracil" while the "Himka Cliff" Proposition led our intrepid explorers right to the "Yugdrasil". (The first spelling in this entry, despite all the extra consonants, is the correct one. 8-))

    Enterprise (Transportation, 3 and 4)
    Another airship turned into a shipwrecked trade ship in the Proposition "Larner Channel Waves".

    Excalipur (Weapon, 5)
    Gilgamesh's very weak sword is ressurrected as the "Excalipar" Treasure, which nevertheless says it's still a fairly strong sword, a patent lie.

    Gysahl Greens (Item, entire series)
    The Proposition "Chocobo Restaurant" describes a restaurant named Gizarl's.
    Fargabaad (Place, 3)
    The U.L. "Falgabird" accurately describes this Magic Knight town from 3.

    Forbidden Land Eureka (Place, 3)
    Although a land of monsters and treasure in FF3, the Tactics U.L. is a former capital of an ancient kingdom.

    Gilbert (Character, 4)
    He and Anna write love letters to each other in "Letter To My Love" and "Joyous Song For You".

    Gisahl (Place, 3)
    The "Chocobo Restaurant" (in the Proposition of the same name) is called Gizarl.

    Mosfungus (Enemy, 5)
    In FFT, Mosfungus is a deadly poison. The Mossfungus in FF5 is an enemy that can be found in the Cleft of Dimension. (sent by UltimaWepn)

    Mount Gulg (Place, 1)
    The Proposition "Girl In Gulg Volcano" takes place here. (Another instance of Engrish.)

    Highwind (Transportation, 7)
    The Highwind has been transformed into a trade ship which was shipwrecked (like every other ship in Tactics) in the Proposition "Salvage The Highwind!"

    Jade Portal (Place, 2)
    The description for the Shrine of Chaos says that Jade, king of Hell, was buried nearby. (The Jade Portal leads to Hell, by the way.)

    Lonka (Place, 5)
    In 5 it was an ancient civilization. FFT mixes many different things in it; the Mirage Tower (U.L.) supposedly leads from a Lonkan castle to earth (there was indeed a flying Lonkan Ruins in 5, but this is represented by the U.L. "Ronkan Ruins" which accurately describes the Ruins from 5.) Matoya (from the Matoya's Cave U.L.) supposedly lived in Lonka as well.

    Lugae Borg (Enemy, 4)
    The form Dr. Lugae transforms into is recreated here as an item horribly translated as Yugeivogue.

    Materia (Term, 7)
    The four Materia Treasures are references to FF7, but it claims that Materia came from Salonia, a place in FF3. Red materia was used for summons, blue for support, and Black and White Materia were part of FF7's storyline.

    Matoya (Character, 1), Matoya's Cave (Place, 1)
    Matoya's Cave is a U.L., but in FFT Matoya is male and worked in the Lonkan Empire. See Lonka.

    Mindu (Character, 2)
    The "Minu Orb" Treasure, which supposedly contains the soul of the first magician, Minu (aka Mindu) is a reference to the magician from FF2.

    Tower of Mirage (Place, 1)
    According to FFT, the U.L. Mirage Tower connects the Lonkan castle to earth. See Lonka.

    Citadel of Trials (Place, 1)
    A nice mix-up in the description. Mount Ordeals (a similar place in 4) was where Cecil went to become the Paladin, whereas Citadel of Trials was actually from 1 and held the Rat's Tail. According to FFT, the Castle of Trials (U.L.), another name for Citadel of Trials, was actually Baron's military school, where the Red Wings graduated from. See Baron.

    Pandemonium (Place, 2)
    The description for the U.L. Pandemonium is identical to its role in FF2 (as Pandaemonium).

    Phantom Train (Place, 6)
    FFT calls it the Magic Train (U.L.) and also calls it the "carrier of the dead", an accurate description.

    Salonia (Place, 3)
    The four Materia Treasures supposedly came from here (although materia didn't exist till FF7. 8-))

    Sand Worm (Enemy, entire series)
    Discovered in Proposition "Ruins At Bed Desert".

    Semitt Falls (Place, 2)
    Accurately described in the U.L. "Semitt Falls" as a place in the Paramecia Empire which holds Mithril.

    Setzer Gabbiani (Character, 6)
    Setzer and his casino ship, Black Jack, show up in the "Wandering Gambler" Propositions.

    St. Elmo's Fire (from FF7)
    The enemy in the Underwater Junon Reactor which yields the Guide Book if Morphed (it's a long story) uses a special attack called St. Elmo's Fire. The real St. Elmo's Fire is a weather phenomenon experienced by sailors which only occurs during electrical storms. It's also a Treasure in FFT.

    Sylx Tower (Place, 3)
    The Crystal Tower U.L. is supposed to be the Sylx Tower, but in FFT it was supposedly part of the Baron Castle. See Baron.

    Tower of Babel (Place, 4)
    The Tower of Babel U.L. reaches from earth to heaven (FF4's Tower of Babel did indeed reach from the underground to heaven). FFT also calls it "Giant's Tower" - a reference to the Babel Giant from 4.

    Tozas (Place, 3)
    The U.L. "Touzas Village" more or less describes the village of midgets (which it calls Lilliputians, a reference to "Gulliver's Travels") from FF3; however, it adds that it was liberated from dictatorship by a giant, Atlas, who doesn't appear in the game.

    FF Tactics Advance Crossovers

    Like FFT, the huge inventory, mission list, and quest items contain lots of references to other FF games. Note that some more crossovers are indicated in the World of Ivalice. To whit:

    FFU Crossovers

    FFCC Crossovers

    FF1+2: Dawn of Souls Crossovers
