The Ruins of the Light Novel Undefeated Bahamut Chronicle contain treasures, lost technology, Abyss that all world powers seek to claim, but they're also home to the deadly Ragnarok and mysterious Automata. This page is a collection of tropes for the characters associated with the Ruins. Fans of only the anime and manga must beware of spoilers.
open/close all folders
Ragnarok
Metatron
Metatron
An angelic Ragnarok that guards the first Ruin Babel.- Attack Reflector: It's signature ability is to reflect attacks, but the moment it does so, there's a brief moment of vulnerability. Exploiting this duration is difficult without using <Reload on Fire> to slow the Ragnarok down or using <Photon Dive> to block the reflected attack at point blank range.
- Mighty Glacier: It's hard to kill and has a powerful laser eye, but it also has a slow flying speed.
Fenrir
Fenrir
A lupine Ragnarok that guards the second Ruin Dungeon.- An Ice Person: It has a freezing breath attack and it can form an ice armor.
Poseidon
Poseidon
A squid-like Ragnarok that guards the third Ruin Ark.- Healing Factor: It has regenerating abilities, allowing it to get back up despite Celestia seemingly defeating it.
- Worf Had the Flu: It was in a weakened state when Celestia and Lux defeated it, and was barely hanging on despite having implants from Yggdrasil.
Deus ex Machina
Deus ex Machina
A mechanical Ragnarok that guards the fourth Ruin Hall.- Lightning Bruiser: Due to its teleportation, it's very evasive for a Ragnarok. It also has enough durability that Bahamut can barely scratch it.
- Weaponized Teleportation: It can teleport both itself and its enemies, though it can only concentrate on a few targets at a time.
Yggdrasil
Yggdrasil
A tree-like Ragnarok that guards the fifth Ruin Gigas.- Adaptive Ability: It gets stronger and faster the more attacks it takes and can heal faster than it can be damaged, meaning the best way to defeat it is to destroy its core in one shot.
- The Symbiote: A part of it lives inside Philuffy and can control her. Once its main body is temporarily killed, Philuffy can use the Ragnarok's power to strengthen herself and turn Typhon into B-Blood Typhon. Its fragments were also used to strengthen several Heiburg Drag-Rides and Poseidon.
Iblis
Iblis
A demonic Ragnarok that guards the sixth Ruin Garden.- Mind Rape: Combined with Brown Note because its powers work based on sound. It can force its victims to see nightmare scenarios, causing them to attack each other. Baptism or Elixir usage allows one to resist these effects.
- Worf Had the Flu: Iblis was intentionally weakened by Hayes and the Dragon Marauders so they can take its Grand Force after Syvalles defeats it.
Phoenix
Phoenix
An avian Ragnarok that guards the seventh Ruin Moon.- Playing with Fire: Not only can it shoot flame arrows, it also uses oil to make the arrows harder to put out.
Sacred Eclipse
Sacred Eclipse
A humanoid Ragnarok who is capable of ending humanity.- All Your Powers Combined: She exhibits abilities from other Ragnaroks, such as Yggdrasil's ability to adapt to enemy attacks and absorb Abysses. Worse yet, she can also wield Divine Drag-rides, as shown when a fragment of her pilots a copy of Bahamut while imitating Fugil's technique.
- Bishōnen Line: She is the most powerful of the Ragnarok, despite being human-shaped and -sized.
- Came Back Strong: Every time she revives, she gains another Ragnarok's ability. After being defeated in Volume 14, the cast predicts that she'll have all seven Ragnarok's abilities during her next attack.
- The Chooser of the One: Due to her abilities to read people's hearts, she can choose someone to help Fugil shape history.
- Fusion Dance: In Volume 14, she fused with Hayes and gave her the ability to use all the other Ragnaroks' powers. After Fugil defeats the Paladins, she fuses with Raffi after the latter receives enough Baptism.
- Gone Horribly Wrong: Zigzagged. She was originally created to benefit humanity as shown by the benevolent actions of her Surface side. Unfortunately, she mostly acts as a berserk Ragnarok and is the strongest one to date. However, Listelka claims that it was also designed to kill indiscriminately against anyone who isn't a Lord or part of the ancient race who created the ruins, possibly making it a case of Gone Horribly Right. In Volume 14, Fugil claims that Sacred Eclipse is broken somehow and needs to be corrected so she can save the world.
- Humanoid Abomination: She usually takes the appearance of her own creator, but she's actually the strongest Ragnarok.
- I'm a Humanitarian: Any who fuses with Sacred Eclipse, no matter how noble their original intentions, will have cravings for humans, due to how Elixir is made from humans.
- Recurring Boss: Even if her core is destroyed, she'll eventually revive stronger than before.
- Shapeshifter Guilt Trip: Her specialty is transforming into someone her opponent feels guilty about in order to distract them.
- Split Personality: She has a "Surface" side and a "Reverse" side, with the former responding to people's wishes to save their loved ones and the latter being a standard hostile Ragnarok.
- Villainous Rescue: Combined with Super-Empowering. Her Surface side will save people with Elixir if someone wishes hard enough for it. So far, she has revived Philuffy, Singlen, Gerdaf, Greifer, and Lux.
Automata
Yos Tork
Yos Tork
Drag-Ride: Peluda
The Automaton who manages the first Ruin Babel.- Back from the Dead: She's killed by Singlen, but all Automata have the ability to revive some time after dying. Singlen is aware of this, but kills her anyway so that she can't listen in on his conversation with Lux, and therefore has nothing to report once she revives.
- Fantastic Slur: She's angered when Yoruka calls her a puppet.
- It's Personal: She hates Singlen for ambushing and killing her, and is disappointed that she can neither fight him (as he's already killed by Fugil) or fight someone who defeated him.
- Sensor Character: Her Divine Raiment, <Red Marker>, allows her to turn the shedded pieces of her armor into device that can detect anything, which is why she acts as a security guard for Avalon.
- Shadow Archetype: Yoruka compares Yos Tork's blind loyalty to Arshalia to the way she blindly followed the Arcadia Empire's contract.
- Shed Armor, Gain Speed: Due to Peluda's Divine Raiment and armaments that can reassemble her armor, Yos Tork specializes in Break Purge, a technique to shoot Drag-Ride armor as a projectile.
- Taking You with Me: When she's defeated by Yoruka, she has all the armor pieces of Peluda resonate and unleash electricity in order to take her opponent out too.
Lu Caria
Lu Caria
Drag-Ride: Quetzalcoatl
The Automaton who manages the second Ruin Dungeon.- Hack Your Enemy: In a similar vein to Yato-no-kami's <Spell Code>, Lu Caria's Divine Raiment, <Switch Loader>, can interfere with the opponents' control of the Drag-Ride by randomly tampering with calculations within the Drag-Ride itself. As a result, her opponents cannot attack accurately.
- Summon to Hand: Her armament, Palette, allows her to teleport her stockpile of blades to her hands.
La Krusche
La Krusche
Drag-Ride: Vouivre
Voiced by: Maria Naganawa
An artificial humanoid found by Lux, Krulcifer and the Triad while investigating the Ark.
- Affectionate Gesture to the Head: Krulcifer pets her on the head shortly after she's activated in response to being flattered. She greatly appreciates it.
- Amnesiac Dissonance: Due to being deactivated for an excessive period of time, she did not have access to her primary data bank. This triggered her default cute, bubbly personality. Once she's reconnected with the archive, she immediately becomes violent and murderous, attempting to kill the protagonists, without exception, because she sees them as intruders, and enemies of her "master" Hayes.
- Beware the Silly Ones: She seems like a silly automaton with a clumsy personality, at least until Hayes shows up. At that point, her personality does a 180 because she follows Hayes's reasoning that Lux holds the burden of his ancestor's crimes against the Lords. She proceeds to control three unmanned Drag-rides and puts them into Over Limit to kill the protagonists. She's also helping Fugil kill anyone who disrupts the world order.
- Black Eyes of Crazy: When her loyalty switches to Hayes, her eyes briefly turn solid black.
- Brainwashed and Crazy: Given the reveal about how Hayes's Baptism works, her Face–Heel Turn wasn't done of her own free will.
- The Bus Came Back: After Fugil fully activates Avalon, he takes control of her and other Automata in order to assassinate anyone who threatens his plans.
- Butt-Monkey: Her fellow Automata make fun of her for being scatterbrained.
- Cloud Cuckoolander: She and her behavior are quite odd, often throwing herself to the ground and going "time to sleep" when she's reached the end of any instruction or task. In fact, she does this several times when introduced, until she realizes Krulcifer is completely ignorant of what was common knowledge at the time the ruins were fully active.
- Face–Heel Turn: She winds up working for Hayes, despite being initially loyal to Krulcifer. Despite Hayes being killed off, she still sides with Fugil because he's in control of Avalon.
- Fish out of Temporal Water: She's been out of action in those ruins so long, the chamber around her has numerous stone pillars having collapsed from age.
- Hates Being Alone: Shortly after being found and activated by Krulcifer, she repeatedly begs Krulcifer to not throw her away. Krulcifer fully intended to keep her, and happily said so, until Hayes commandeered her loyalty.
- Loyal Phlebotinum: She will obey the orders of anyone she recognizes as "Administrator" without exception, if it's in her capabilities, but there are tiers of authority that she must obey. Hayes has a higher tier than Krulcifer.
- My Master, Right or Wrong: She will always defer to those with higher authorities in the ruins.
- Practical Taunt: While all the Automata taunt their opponents, taunting is a major part of La Krusche's strategy. If she can make her opponent agitated, their thoughts will be easier to read with her Divine Raiment, <True Eyes>.
- Ragnarok Proof: She's found under a collapsed stone pillar, and is still fully functional. At the end of episode 8, the battle with Ragnarock causes a tremendous amount of debris lands on her, and either she is still fully functional to pilot Hayes's giant in episode 12, or it's a near identical model. The light novel confirms that the one in Gigas is a different automaton named El Fajura.
- Ridiculously Human Robot: She was specifically built to have human form, and programmed to act in a mostly human manner.
- Telepathy: Vouivre's Divine Raiment, <True Eyes>, allows her to read her opponent's mind.
- Translation Convention: For some reason, she both understands and speaks the same language as the main characters. This is justified as Krulcifer did gain access to documents written in the same language as is currently spoken in the New Kingdom in an earlier ruins exploration, implying that the common tongue has not significantly changed since the ruins were originally built.
- Was Once a Man: The Automata were once a group of sisters from the Xfer clan who all suffered from a terminal illness, only to be turned into androids by Arshalia.
Ney Louches
Ney Louches
Drag-Ride: Salamander
The Automaton who manages the fourth Ruin Hall.- Bait the Dog: She didn't turn against Krulcifer in Volume 7, due to Hayes being in recovery at the time. This makes it seem like she'll be the only Automaton to stay benevolent, but she later joins the other Automata in serving Fugil and Raffi, killing political enemies on their behalf.
- Combat Pragmatist: She intentionally starts a forest fire to make it harder for her human opponents to breathe.
- Playing with Fire: Her Divine Raiment, <Flame Nova>, allows her to control fire. She also uses oil in order to spread fire all over the battlefield.
El Fajura
El Fajura
Drag-Rides: Python and EX-Wyvern
The Automaton who manages the fifth Ruin Gigas.- Adapted Out: She doesn't appear in the anime despite being in Volume 5. Instead, La Krulshe takes her place in assisting Hayes.
- Nanomachines: She has the ability to control nanomachines, allowing her to strengthen allied Drag-Knights and form combat-ready clones of herself.
- Puppeteer Parasite: Python has a Divine Raiment that can stick to another Drag-Ride and manipulate the pilot's mind. El Fajura uses this on Philuffy to trick her into fighting Lux.
Clan Lieze
Clan Lieze
The Automaton who manages the sixth Ruin Garden. Re Plica
Re Plica
Drag-Ride: Gargoyle
The Automaton who manages the seventh Ruin Moon.- Foreshadowing: In the fan-translation, she tends to use "desu" as her verbal tic and has a silly personality. She also reacts strangely to Krulcifer's voice. These are hints that she's actually an Automaton.
- Heel–Face Revolving Door: She starts out as Soffice's loyal aide, only for the two to turn out to be antagonists. Then she's taken over by Hayes and turned against Soffice, only to be freed from Hayes's control and restored to her original personality. After Fugil activates <Endless>, she's helping him and Raffi kill political enemies.
- Punny Name: Her real name is Re Plica.
- Villain Override: Like La Krusche, she ends up under the control of Hayes, causing her to attack Soffice via Neck Lift.
Arshalia Rei Arcadia
Arshalia Rei Arcadia
Drag-Ride: Ouroboros
The Automaton who manages the Zero Ruin Avalon. Not to be confused with the Lord of the same name.- Affably Evil: She may be on Fugil's side, but she is genuinely polite to Raffi and takes the time to give her constructive criticism. She's also surprisingly honest about the possibility that she and Fugil will betray Raffi, though that may have been a warning not to act against Fugil's ideals.
- And Then What?: She states that even if the protagonists win against Fugil and stop <Endless>, they could later end up facing a corrupt regime that can't be overthrown without using <Endless>. She then asks them if they have a plan for such a situation.
- The Dragon: Of all of Fugil's allies, she's the most privy to his plans, having helped him use <Endless> several times in the past. She also helps him in combat by operating Ouroboros's main body while he uses a copy of Bahamut.
