History Superboss / AnotherEden

** After you've escaped The Blood Ring, returning to Entrana opens up a sidequest where you're tasked with investigating the craters where red meteors have crashed into the landmasses of Platonos. Inside each is a Lavog, which have massive defenses, two health bars each with a stopper, and they also summon adds to complicate the fight, as you have to kill a specific body to end it. After you've beaten all five, you trace them to their source in The Blood Ring and engage a giant Lavog using Guilty Hades. Besting this beast further upgrades Cyrus' personal weapon.

** Again, the Extermination Jobs have a final fourth tier that needs you to hunt down very powerful monsters while fighting in extreme weather conditions, though accessing them is a lot simpler compared to some Omegapolis bosses. Defeating each yields one of the Dryad's weapons.

** Abominus is ''populated'' with powerful giant that can wipe the floor with your HumongousMecha until you've hunted everything else to unlock its highest tiers of upgrades. The deepest reaches of this island hosts Megalowyrm Genesormr, which is a tough fight even with a fully kitted-out mech, but its defeat yields the Bolt Core which is needed to unlock Hyuga as a sidekick.

** An additional update released in v3.0.500 adds an extra sidequest that allows the player to challenge Amal Gamal, a bizarre lifeform that seemingly takes traits of other lifeforms around it. Like one of the Head Bounties, it sports a large pool of HP and fought under the damage-reducing Phantom Mist climate. Not only does it pack a punch on its own, some of its passives also ''punishes'' the player if they attempt to AttackItsWeakPoint. Defeating its full form nets the player with grasta for "Spicy Lover" personality.

** After clearing "Edge of the Vortex", the player can challenge the Warped version of its FinalBoss, which has the habit of healing itself at turn-end if there are less than four party members in the frontline ''with the same elemental affinity'', among other things. Successfully beating it rewards the player with AS Noahxis' true grasta.

** Also available after reaching the true end of "Wanderer in the Binding Night" is the "Blackbird" sidequest, which introduces Gatekeeper SD-148. While offensively much weaker compared to the Time Anti-spiral, it also has various troublesome gimmicks to make up for it such as preemptive Earth zone, status effects infliction, MP drain, and ''50-hit count'' damage immunity barrier. Defeating it not only nets Almighty grasta for "Avenger" personality, but it will also open the (currently Japanese-only) sidequest for unlocking AS Noahxis.

** Completing the true end of "Wanderer in the Binding Night" final chapter opens up a sidequest to battle a massively powered-up version of Time Anti-spiral, which not only possesses large reserve of HP, but will also revive a few times before it is defeated for good. The boss uses attacks those will (a) FixedDamageAttack that can take up to 50% ''of your max HP'', (b) will chip down your party's type resistances, (c) or after a few revives, use both successively ''in the same turn'' -- yet on the other hand, you're discouraged from debuffing its ATK and INT too much until below 200 because its "Correction" auras will activate and instead ''supercharge it'', guaranteeing a TotalPartyKill. Triumph over it, however, and it will net Nona's personal armor.

* The "Wanderer in the Vortex" Apocrypha has a side area in Arat where you can challenge additional bosses and build structures that can aid you in battle with them. The first, simpler variant of each boss is needed to access the True End of its respective chapter. You then unlock the Hard version of that boss, which is much harder and needs specialized strategy to defeat.
* After completing the True End of Chapter 4 of "Wander in the Vortex", you can also unlock a series of {{Fetch Quest}}s to rebuild a Karakuri. When you first fight it, it's incomplete and therefore a pushover, and as you progress this you get rematches at different stages of completion, each more difficult than the last. When the Karakuri is fully built you're going to need to give it your all to beat it.

Superbosses serve as the end- and post-game content for the game, with nearly every update adding more to test the player. They have hundreds of millions of HP, stoppers to prevent bursting down with Another Force, and strong attacks that deal loads of damage without mitigation. The game also [[ReadingsAreOffTheScale doesn't display their level]], and you'll need a maxed-out team and specialized tactics to even stand a chance. Most yield rewards like [[InfinityPlusOneSword some of the strongest equipment in the game]], and defeating them will certainly accomplish an achievement that comes with a good bounty of Chronos Stones.

** After completing Chapter 6, the player will gain access to a series of {{Fetch Quest}}s that unlocks the fight against Melozia, a shapeshifting BonusBoss. In the beginning of the battle, it will take on Aldo's form, then to Thillelille and Prai in the second phase, and finally into Melina, Rosetta, and Mistrare in the final phase. The player needs to defeat the Aldo, Thillelille, and Melina copies respectively.

** An additional update released in v3.0.500 adds an extra sidequest that allows the player to challenge Amal Gamal, a bizarre lifeform that seemingly takes traits of other lifeforms around it. Like one of the Head Bounties, it sports a large pool of HP and fought in the area where Phantom Mist effect is active and thus causing damage reduction. Not only it packs a punch on its own, some of its passives also ''punishes'' the player if they attempt to AttackItsWeakPoint. Defeating its full form nets the player with grasta for "Spicy Lover" personality.

** If you've been a little thorough with exploration, one side dungeon will lead you to unwittingly awakening the [[spoiler:Aspid]], and it can be found out in the Vande Sea after that point. However, confronting it unprepared results in HopelessBossFight where your party will be unable to deal damage ''at all''. Instead, the player has to go through a series of sidequests in order to weaken it first before being able to stand a chance, and defeating it allows the player to obtain Elpis Hammer.

** The ultimate goal of the bounty hunting sidequest is to raise through the ranks and find clues those lead to the four [[TheMostWanted Head bounties]] -- the most dangerous criminals among the Meks. Defeating them nets the crests required to obtain some of the [[InfinityPlusOneSword Elpis weapons]]. [[spoiler:Furthermore, clearing them all unlocks an additional fight against the very same lowly bandit you caught on your first bounty, except this time he is [[FromNobodyToNightmare massively powered up and possessing absurd amount of stats]], and his defeat allow you to get the Elpis Sword.]]
** While voyaging the Vande Sea, there is a chance to run into [[spoiler:Aspid]]. However, confronting it unprepared results in HopelessBossFight where your party will be unable to deal damage ''at all'' and gets wiped at third turn. Instead, the player has to go through a series of sidequests in order to weaken it first before being able to stand a chance, and defeating it allows the player to obtain Elpis Hammer.

* Uquaji can be found in the Timespace Rift, and while he starts as a pushover Level 1 enemy, he returns after a set time interval with more strength. After enough rematches he scales past your party's level cap, going as high as Level 195. Defeating him at his strongest adds him to your roster, and you get to fight a rematchable Uquaji Clan for Uquaji Coins to exchange for unique weaponry.

* In Nazrik, collect all ten pieces of Dirty Puzzle Pieces for a collector NPC in the outskirts of the city, and they will give access to manhole leading to an area where the player can re-challenge massively powered-up versions of the Dark Spirits and the dogu-guarded bosses from previous chapters. They possess ''huge'' HP reserves and their teamwork can make for a very challenging fight, but overcoming them nets the Void Weapons, which grant their wielders guaranteed {{Critical Hit}}s.

** The Future era has a set of eerie geometric-looking enemies [[spoiler:which are actually artificial spirits made by the People of Paradise and dumped to the player's home planet due to flaw in their cores]] - Imbrium Basin in Last Island, Insula Ventorum in Macminal Museum's restricted area, and Terra Nivium in the basement of Sky Fortress Eeza. Like the Unseen, all of them have random attack patterns those make their movements difficult to anticipate...\\

...and then, after completing Chapter 8 of this Mythos, the player can fight ''massively'' powered-up versions of the bosses above in the Antiquity era alongside two more of them: Lacus Solitudinis and Sinus Aestuum. All of them not only retain the random attack patterns, but also have ability to overwrite Zones when the player least expect it.

** [[spoiler:ARPX-Sophie]] may have low health and defenses, but defeating it will cause it to revive and it can do so indefinitely. The same goes for the elements that accompany it in battle. You defeat the battle not by depleting their health bar, but by doing enough damage to cancel the ChargedAttack of each one, forcing the main boss to build up one of its unique stacks. After you hit 10 the battle ends in your victory.

* After completing the True End of Chapter 4 of "Wander in the Vortex", you can also unlock a series of {{Fetch Quest}}s to rebuild a Karakuri. You get a few rounds against it at each stage of construction and it's not too hard, but when the Karakuri is fully built you're going to need to give it your all to beat it.

* The "Wanderer in the Vortex" Apocrypha has a side area in Arat where you can challenge additional bosses and build structures that can aid you in battle with them. The first, simpler variant of each boss is needed to access the True End of its respective chapter. You then unlock the Hard version of that boss, which is much harder and needs specialized strategy to defeat.

* Chance Encounters (denoted by red icons) are a series of very difficult boss fights, but completing all of them yields a new character, or the 5-star advancements of certain story characters.

* After unlocking the 5-star classes for the second wave of the ''Tales'' units, you get to rematch the boss that you fought to get their upgrade items. This time, it's a lot stronger than before, and defeating it in that state will yield the corresponding character's Valor chant Grasta.

* After unlocking the 5-star classes for each of the ''Tales'' units, you unlock the True Spirit Trials that yield each characters' True Valor Chant Grastas. These bosses are almost as difficult as the Twins, sporting HP stoppers to keep you from bursting them down, and repeatedly altering Zones to tip the tide of battle when you least expect it.

The first, simpler variant of each boss is needed to access the True End of its respective chapter. You then unlock the Hard version of that boss, which is much harder and needs specialized strategy to defeat.
* Completion of the "Crown of the Pale Dawn" Symphony opens up a locked room in Fraxinus Labs. You get to fight against a Raptor bot that inherits the moveset of the chosen ''Tales'' character. This yields the tome needed to advance that character to 5 stars. After completing all four, you get a rematch with the Raptor, and it hits much harder, but defeating it will yield the personal Grastas for the corresponding characters.
