Storm Emperor, known as Dragon and Kaminari to Tomo ni Arawareru Mono (雷鳴と共に現る者, roughly translated as "It who appears with thunder") in Japan, Tiamat in certain European translations, and Klanvaline in Etrian Odyssey II, is a long, three-eyed draconic serpent which closely resembles oriental dragons and enjoys soaring stormy skies. It has four clawed legs that it probably only uses to attack, as its body is always levitating. It also sports long, red whiskers, a pair of blade-like horns, and a trident-like tail, all of these most likely used to capture and control lightning.
Its breath becomes a rampaging storm of powerful lightning that steals the life of whoever it strikes; its third eye may cast a powerful curse as well.
It is one of the three elemental dragons; usually regarded as the easiest to handle, but still powerful enough to destroy overconfident parties. Its battle theme is usually Scatter About, and can only be fought in the postgame.
The Dragon is the only one of the trio that is not particular on its chosen habitat. However, it seems to prefer ruins as it inhabits both the deepest level of the Lost Shinjuku and an abandoned portion of the Petal Bridge, indicating that it prefers locations with minimal human traffic.
It should be noted that it is more likely to use its Instant Death skills the more buffs the player party has, effectively dooming you if you rely heavily on them. As such, buff classes should opt not to place any more than one or two at a time. The exception to this is the Dancer class, since they boost allies whilst only applying a buff on themselves.

The Dragon can be found on 25F, at the same location where Etreant was fought. Naturally, it is only accessible in the postgame, as with the quest that unlocks it.
The Dragon's strongest attack is Voltage, which delivers devastating volt damage to the whole party, and must be parried with the Protector's Antivolt skill to survive. Its arm-reliant skills are only used when its head its bound, so if you can nullify Voltage, the only remaining threat is its normal attack.
The Dragon is also programmed to use Corrupt to erase the party's buffs if they have any. However, since this move doesn't do anything else, this turn is essentially a free turn where the party is not under threat. It can't use Corrupt twice in a row, so on turns after Corrupt, re-establish the buff and prepare for Voltage, and you'd only have to worry about its normal attack. Because of this AI quirk, the Dragon can become the easiest of the three Elemental Dragons in this game to defeat.
Skills[]
- Voltage (Uses Head): Deals high Volt damage to entire party.
- Curse (Uses Arms): Very high damage to a party member, heals Dragon by percentage of damage done. Uses when head binds after Shield.
- Shield (Uses Arms): Increases Dragon's defense for 5 turns. User immune to all attacks. Uses when head binds.

Dragon reappears in Etrian Odyssey II on B17, now with more attacks and much less HP than in Etrian Odyssey. It now possesses HP absorb skills and inflicts Terror, though it is still the easiest of the trio. In order to fight it, a quest must be accepted.
It also makes an early appearance at the end of the quest 'Dazed and disoriented', just as the party manages to rescue the lost soldier. If the party has been taking up every quest as it appears throughout the game, they will be ill-suited to take on the Dragon at this point. The game even suggests to the player to retreat. However, if they do fight and defeat the Dragon here, not only does the player reap its drops, it also leaves behind a hefty additional reward of 50,000en. This does not affect the player's ability to challenge it again much later in the game.
Skills[]
- Voltage (Uses Head): Deals very high Volt damage to the party, antivolt can completely parry it at high levels.
- Curse (Uses Arms): Deals very high damage to a party member and steals their HP; half of the damage is absorbed. May inflict Curse.
- Blow (Uses Arms): Deals medium damage to all the party, inflicts terror.
- Fury (Uses Head): Raises Dragon's strength.
- Fang (Uses Legs): 3-4 attacks across random party members, decrease defense.
Drops[]
- Volt Scale (Worth: 20000 en)
- Amp Barbel (Conditional) (Worth: 50000 en)
- Condition: Defeat with a Volt attack.

The Storm Emperor returns in Etrian Odyssey 2 Untold again as a post-game boss. In order to fight it, you must complete a long questline related to the birdfolk.
Surprisingly, the out of the three elemental dragons, the Storm Emperor is the one that is given the most importance through the game. You first meet it during the quest 'The Golden Shadow', where you must rescue a group of soldiers being kept captive by the dragon, where you get a chance to battle it at the end. Since this is much earlier than you are supposed to fight it, it isn't recommended to do so. However, should you choose to fight it and survive for that long, after 4 turns the dragon will run away. No additional quest rewards are given, but the quest's dialogue will change slightly should you complete such a feat. If you somehow manage to defeat it after preventing it from fleeing by binding its legs, the quest's dialogue will change yet again and you will receive an additional 100,000 ental on top of the regular quest rewards.
Later on the story, the Storm Emperor will attack High Lagaard directly, being the first time any of the dragons directly attack any of the game's major cities. It will also attempt to destroy the safe where the Birdfolk stores most of their relics, where it is revealed that they have a long lasting rivalry with the dragon, whom they named Klanvaline.
The dragon is finally battled in the quest 'The Volt King's Rampage', which grants the player access to the outer rim of 19F. The journey to the Storm Emperor leads the player around the outside edge, dodging Wandering Eyes and going back around 18F until they reach the upper-right corner of 19F. However, after being defeated, despite its grievous wounds the dragon will attempt one final attack on High Lagaard with little strength it still has. At this point, the bird that you saved at the quest An Ethical Dilemma will help holding it down, but unless you have a survivalist or a gunner on the party, the mighty dragon will turn its attention to the chick. Regardless of either outcome, the dragon will be interrupted by Canaan, who finishes it off with the Divide Bow, one of the sacred relics of the bird folk, and perhaps the reason why the Storm Emperor attempted to destroy the Bird Folk's safe.
After the rampaging dragon is put down, Canaan hands the Divide Bow to you. It is, in terms of pure ATK stat, the strongest bow in the game.
