Chronodia is a superboss from the original Final Fantasy found in the 20th Anniversary remake and subsequent versions of the game based on it. She awaits players brave enough to venture to the deepest level of the Labyrinth of Time. There are eight different versions of Chronodia to fight, depending on how many blue and red seals the player has unlocked, with more blue seals leading to more powerful versions and more red seals leading to weaker versions.

Chronodia resembles the Seven Heroes, the final boss from Romancing SaGa 2, and may have been inspired by it.


Chronodia's stats and battle reward depend on the colors of seals the player has unlocked when going through the labyrinth. The rewards are Maximillian for #196, Lust Dagger for #197, Golden Staff for #198, Master Shield for #199, Shadow Mask for #200, Lordly Robes for #201, Survival Vest for #202 and Barbarian's Sword for #203. Thus, to fully complete the bestiary and get all rewards, the player will need to complete the labyrinth eight times to fight all different variations.


Chronodia appears as a monstrous woman with various appendages protecting a sphere, which is surrounded by the Four Fiends that served as bosses earlier in the game. The weakest version (#196 in the bestiary) has no fiends "attached", while the strongest version (#203 in the bestiary) has all the fiends, and what looks like a head of Chaos coming out of Chronodia's hair, along with various extra weapons surrounding her. The more attachments, the stronger Chronodia becomes, as if she absorbs their energy.

Chronodia gains more attachments the more blue seals the player has unlocked rather than red seals.


Every version of Chronodia has the following two abilities:

  • Regular Attack — Powerful physical damage to one target. The party should apply several Invisira spells to avoid it (especially if Chronodia is under the effects of Haste), and possibly Protect/Protera as a backup.
  • Seal — Locks a command. Only one command can be locked at a time. Chronodia uses this ability every fifth turn. Wears off in 4 turns. If "Fight" is disabled, the player should use spell casting items to continue to attack. If "Item" is disabled, the player should keep their White Magic user alive at all costs.

For spells and enemy abilities, each version uses a different subset of the following attacks:

The spell cycles of each version, as well as their chances to cast a spell each turn, are as follows:

  • #196: (5/16 chance) Stop → Haste → Warp → Slow
  • #197: (33/64 chance) Blizzaga → Stop → Haste → Warp → Slow → Flare → Kill → Flare
  • #198: (13/32 chance) Firaga → Stop → Haste → Warp → Slow
  • #199: (20/64 chance) Stop → Haste → Warp → Slow
  • #200: (72/256 chance) Thundaga → Stop → Haste → Warp → Slow
  • #201: (1/2 chance) Blizzaga → Firaga → Stop → Haste → Warp → Slow → Flare → Kill
  • #202: (136/512 chance) Thundaga → Stop → Haste → Warp → Slow
  • #203: (12/32 chance) Blizzaga → Flare → Firaga → Thundaga → Stop → Haste → Warp → Slow

And her skill cycles are:

  • #199: (11/64 chance) Ink
  • #200: (69/256 chance) Thunderbolt → Poison Gas → Icestorm → Blaze
  • #202: (141/512 chance) Ink → Thunderbolt → Poison Gas → Icestorm
  • #203: (5/32 chance) Ink → Thunderbolt → Poison Gas → Icestorm

Chronodia always uses Seal every fifth turn. This action is independent of her ability cycles and does not advance her current placement in either the spell or skill list. As a result, she breaks the normal maximum of 4 entries in her skill list.

When all commands are available to the player, the Seal has worn off, which provides an indication that Chronodia will use Seal in the next turn. Since Seal does no damage, no healing spells are needed, meaning the player gets a "free" round for attacking with everyone.

At one point in development, it may have been intended for Chronodia's physical attacks to inflict a status condition, because her physical attacks are set to check resistance to the Time element upon inflicting a status, but aren't given any status to inflict.


While Chronodia is tougher than Omega and Shinryu, the strategies used to fight her are similar: the player should use the healing pot in the room before the battle to clear status effects and restore HP and MP. If the party's level is low, or Chronodia's using Haste, it is not worth bothering buffing the party, as they will be killed in one hit anyway. The player should concentrate on keeping the party alive in this case. Otherwise, Saber/Haste/Temper/Speed Drink/Strength Tonic are great for the melee members and Protera/Invisira/Blink/Protect Drink/NulAll are great protection for everyone.

These can be achieved using magic and/or items. The player should use Healaga if possible, and otherwise use a Rune Staff or Potion (X-Potions if the party has enough). If someone is knocked out the player should bring them back to life as soon as possible using Full-Life, Phoenix Down or Sage's Staff.

The higher versions of Chronodia have high Defense, severely lowering melee attacks' damage. If these characters are not buffed they will be almost useless for dealing damage. Magic (non-elemental) does the best damage. If the player cannot buff the melee characters (because they die too often), at least they should use items to attack with magic (such as the Judgment Staff and Lightbringer), or heal.

It would be a good idea to have three Judgment Staves in the inventory, and to have one on the Black Wizard. This way, when a Seal blocks the party's magic or attack, it is still possible to hit the boss hard. The fight is easy until a Seal blocks White Magic; this can be dangerous if the party does not have enough healing items.

Temper, Protera, and Invisira all stack, so casting each multiple times can help. A few Proteras can reduce Chronodia's attack to under 200 damage, and Temper stacking can up the characters' attack power to well over 4,000.

Chrono is derived from the Greek word khronos, meaning "time".

Dia means "day" in Portuguese, Spanish and Occitan.

In ancient Greek religion and folklore, Dia means "heavenly", "divine", or "she who belongs to Zeus". The name is attributed to several figures and treated like an honorific or title.
