Fireworms get brighter the closer they are to one another. [src]

The Fireworm (originally named the Flame Eater) is a small Stoker Class dragon that first appeared in Dragons: Riders of Berk.

Official Description[]

A Fireworm Queen lays thousands of eggs in her lifetime and builds a massive nest made of a flammable gel known as 'Firecomb' to house her many eggs.
The only known Fireworm Queen lives on Fireworm Island, in the base of a dormant volcano. Her firecomb nest extends through multiple catacombs where she tends to her baby Fireworms. Like all mother dragons, the Queen is incredibly protective of her home and babies. While aggressive, the Fireworm Queen is not malicious. If an intruder returns stolen firecomb or backs off quickly, she might just let them leave in one piece.
Although her sting is lethal to most humans and dragons, it actually possesses a restorative power for all Stoker Class dragons. One bite from a Fireworm Queen can reignite a Stoker's flailing flames and bring them back to full firepower.
Each Fireworm colony holds only one female, the Queen! Although rare, when a new female is born, she sets out to establish her own colony. Talk about family drama!
When a Fireworm is moved to fight, even other Dragons get out of its way.
  Dragons: Rise of Berk  


Concept art shows Fireworms used to have dark gray scales with red skin underneath, or gray skin that turns red or orange when heated, and appeared to lack wings.

Physical Appearance[]


Fireworm Egg

Egg in Dragons: Rise of Berk


Egg in School of Dragons

In Dragons: Rise of Berk, the Fireworm egg is oval-shaped and has an obvious scale pattern. It has small spikes protruding from its sides and slightly larger ones jut out from the top. Their eggs are normally orange or red in color. In School of Dragons, it is bright orange and yellow with no spines at the sides and the middle.

In Dragons: Race to the Edge, Fireworm eggs appear vastly different from other depictions, being nearly indistinguishable from Firecomb containers. It is possible that only Fireworm Princesses hatch from large eggs, and that the Firecomb eggs seen in the show are of the smaller male individuals.

Average Fireworm[]

Common Fireworms are only about a few inches in length. They have hexagonal orangish-brown scales that glow a bright golden orange color when lit up. They also have five pairs of legs for a total of ten legs and white eyes that glow in the dark. They strongly resemble lizards, with their wide heads and long bodies. When they ignite, they glow orange, and sometimes even light their bodies on fire. From what is stated in the description in Dragons: Rise of Berk, it would appear that the average tiny Fireworms are all males and drones of their respective hives.

In How to Train Your Dragon: The Hidden World, Fireworms appear somewhat larger in size than in the TV series. They have short spines down their backs and some under their throats. They have clearly visible pupils and their nasal horn is colored darker than their skin. These Fireworms also only have four pairs of legs in contrast to the five pairs that their series counterparts have.

Fireworm Queen/Princess[]

Fireworm Queens/Princesses look similar in appearance to the average Fireworm, but have some differences that make them stand out from the rest. For instance, while the common Fireworm can fit in the palm of a hand, the queen is many times bigger, her size is comparable to that of a Boneknapper. She also possesses several horns located at the back of her nape and the front of her snout that together resemble a crown. When not heated-up or near her nest, the Fireworm Queen's normal skin color is a pale gold, with tan colored horns, spots, and underbelly. She also doesn't glow in this state. Fireworm Queens are, like the name suggests, always female and if another female Fireworm were to be born in a nest which already has a queen, the newly born Fireworm (the Fireworm Princess) would fly off to start a nest of her own. Fireworm Queens and Princesses would appear to be the only females in the species.

Titan Wing[]

Titan Wing Fireworm Princess

Titan Wing Fireworms are very colorful. They have a neon green body with distinctive scales. Their head, tail and half their wing bones have hints of cyan while the other half of the wing bone is yellow. The protuberances at the back of their head are yellow too. Their wings are blue in color. A row of thin spines run along their back and they have five pairs of legs.


Body Temperature and Glow[]

The closer two Fireworms are to one another, the brighter they will shine

All Fireworms can heat up their skin to a temperature expressed to be hotter than the sun, hot enough to be able to burn almost anything. Some Fireworm individuals, such as the Plain Fireworm Queen, are able to ignite any flammable material just by touching it. While doing so they also generate a great amount of light, and sometimes, they even set themselves and surfaces they walk on aflame. It would appear that the closer two Fireworms are to one another, the brighter they will shine. This ability is used as means of self defense and for lost individuals to find their way back to the nest. A great number of Fireworms using this ability are virtually unapproachable and undefeatable, only moving when exposed to their main weakness.

Some Fireworm individuals, such as Solar Flare, appear to have extremely hot skin. Due to this, they can only exit their caves during the warmest days of hot summers and they remain in their nests during cooler days. This is probably because reptiles, like dragons, are cold blooded and their body temperature depends on their surroundings, meaning that being in the cold may cause the Fireworm to lose too much heat.

In Dragons: Titan Uprising, a Fireworm individual know as the Fearsome Flamellion seems to burn so hot, that upon heating up its skin it creates massive explosions of intense heat. Its heat is so intense upon igniting itself it was able to burn through a fireproof moat leaving a lake of fire.


Fireworm Queens also appear to have a hotter, less destructive

Fireworms are not shown to be able to breathe any fire, but Fireworm Queens have very powerful, bright, napalm-typed fire breaths that emit small firework-like particles (indicating extreme heat). These flame blasts are surprisingly potent, and visually resemble a mix between a Monstrous Nightmare's and a Red Death's fire breath.

Fireworm Queens also appear to have a hotter, less destructive, more concentrated and accurate version of their fire breath similar in appearance to a Deadly Nadder's magnesium fire breath. It seems that they use this fire type while in their nests to avoid accidentally destroying anything and as a tool, to shape the cave systems near the nest to their liking.

The Fearsome Flamemilion seems to be able to set itself on fire in a similar way to the Monstrous Nightmare and Rockstomper. This might be due to how intense its heat is, causing fire to appear around its body.

Fire Power Combos[]

Fireworm Queens can combine their firepower with other Stoker Class Dragons

As shown in the episode "Crash Course", it appears that Fireworm Queens can combine their firepower with other Stoker Class Dragons (at least Monstrous Nightmares) to create a very powerful, force field-like blast of fire to defeat opponents. This ability appears to regenerate both participant's strength and health as one Fireworm Queen was severely wounded when Hookfang picked her up to initiate the ability, and, after they finished performing their combined firepower, the Fireworm Queen was completely healed and back on her feet. This fire is much hotter than their ordinary fire, as it is able to cook the mucus off of a Cavern Crasher, which the Fireworm Queen was unable to do with her regular fire.

Solar Flare[]

It is stated in the game, Dragons: Rise of Berk that the Fireworm individual Flashfright can create a large solar flare when clapping her wings together. This solar flare can disorient opponents. It is unknown if this is an ability of the whole of the Fireworm species or if Flashfright is the only Fireworm with this ability.


Fireworm Queens are capable of producing a hormonal exudate called "Drottning." When fed to a regular female Fireworm larva, this elixir is capable of turning the larva into a queen, with the individual growing many times larger than an average Fireworm and gaining increased strength, the ability to lay eggs, and the ability to produce Drottning of her own. The more Drottning fed to a larva, the larger and more powerful the new Fireworm Queen will become, with the added effect of giving the dragon greater intelligence and an irrepressibility of spirit. The elixir is produced from glands under a female's tongue. Some Vikings theorize that the Queen's Drottning and not her venom is what enables her to reignite a dragon's fire, although this is debated.

Reflective Skin[]

It is stated in the game, Dragons: Rise of Berk that the Fireworm individual Brightburn possesses uniquely reflective skin that can reflect the light of the sun, which the Fireworm can use to temporarily blind her opponents, leaving them open to the Fireworm's attacks.

Strength and Combat[]

One Fireworm Queen managed to effortlessly pick up Hookfang with her tail

Fireworms, despite their small size, possess limited strength due to their diminutive stature. In one instance, an average-sized Fireworm, comparable in size to a human hand, was observed exerting enough force to move objects within Alex's bag. However, it is worth noting that Fireworm Queens exhibit strength akin to that of a Typhoomerang. These queens possess robust prehensile tails capable of lifting objects weighing over 5,000 lbs or more. An exemplification of their power was witnessed when a Fireworm Queen effortlessly lifted Hookfang using her tail and effortlessly displaced fully grown trees while in search of the Dragon Riders. Additionally, the Fireworm Queen demonstrated resilience when confronted by a Cavern Crasher, although she was ultimately unable to conquer it single-handedly.

Speed and Agility[]

Average Fireworm[]

Fireworms are shown to be relatively fast dragons, being able to outfly Hiccup, Snotlout and Toothless while in the caves of their nest. Due to their small sizes Fireworms are quite agile as well.

Fireworm Queen/Princess[]

Fireworm Queens are fast dragons

Fireworm Queens are fast dragons as one was able to catch up to Toothless, Hiccup and Snotlout while flying in the caves, and then took a short cut and reached the exit before them. She was able to steadily pursue the Dragon Riders's dragons while on foot, even while her targets were quickly flying away from her. She also flew fast enough to find the Dragons Riders and lead them back to her nest before the Cavern Crasher even reached the nest's main chamber. Fireworm Queens are shown to have a flexible body and tail, enabling them to have a prehensile tail and to fly in and out of the complex cave systems that surround their nests.

Endurance and Stamina[]

Average Fireworm[]

Fireworms have shown quite some endurance as they are often tossed around and launched in the air due to their small sizes and inability to cause serious harm, yet they suffer little to no damage. They were shown to have a decent level of stamina when they migrated as shown in Race to the Edge.

Fireworm Queen/Princess[]

Fireworm Queens have great endurance

Fireworm Queens have great endurance. One Fireworm Queen was able to take many blasts from the Dragon Rider's dragons and seemed to suffer no damage at all. She also stood her ground against the Cavern Crasher and, despite having been scratched several times, went looking for help to defend her nest, seemingly unaffected by the damage done to her.

Fireworm Queens have good stamina as well, as Snotlout's Fireworm Queen went through great lengths to defend her nest from the Cavern Crasher. She flew for what was probably days seeking the aid of the Dragon Riders and once she found them, flew straight back to her nest and returned to her duties as mother and ruler of the nest while defending it from the powerful intruder.

Venomous Tongue & Healing Venom[]

One Fireworm Queen demonstrated this ability when she injected and healed Hookfang with her venom

A Fireworm's tongue is capable of injecting a potent venom fatal to all animals, Vikings, and most dragons. As mentioned in the Plain Fireworm Queen's description, the tongue contains enough venom to kill most animals with a single stroke. That same venom, however, can also be used to reignite a Stoker Class dragon's worn-out fire, preventing their imminent death. One Fireworm Queen demonstrated this ability when she injected and healed Hookfang with her venom.


Fireworms have frequently demonstrated great ability by effortlessly climbing in

Fireworms have frequently demonstrated great ability by effortlessly climbing in and about the cave systems that surround their hives, including the slippery Firecomb-riddled walls.


Average Fireworms have not shown much intelligence, but Fireworm Queens have been shown to be particularly intelligent, as one was able to take a short cut to catch up to the escaping Hiccup, Toothless, and Snotlout Jorgenson. This individual also quickly understood that a bond between a dragon and their rider was strong enough to risk their lives for each other. In addition, she was also intelligent enough to know when she was defeated, to know whom to she could trust to help her, and to seek aid from her allies when her nest was being attacked by a Cavern Crasher.


Despite not being in the Tracker Class, Fireworm Queens, particularly Snotlout's Fireworm Queen, displayed a keen sense of smell as she was perfectly able to track Snotlout, Hookfang, and the Dragon Riders down while not knowing where they were and not having seen them for several years.

Social Nature[]

Fireworms always travel in large groups, and, while individually they are not very dangerous, in large numbers they can defeat anything they go up against.


Flame eaters... that's what Bork meant. Those firecombs are filled with the gel. Eating it gives Fireworms their heat. [src]
  — Hiccup  
Average Fireworms produce a wax-like substance called Firecomb

Average Fireworms produce a wax-like substance called Firecomb which they utilize to construct their hives. They also produce a liquid version called Firecomb Gel, the source of their heat and fire power, which is stored in solid Firecomb containers in the nest for later consumption. The Queens eat a constant diet of Firecomb Gel to maintain their high energy output, meaning that they will endlessly pursue anyone that attempts to steal even a single container of Firecomb Gel.

As mentioned in the Plain Fireworm Queen's description, Firecomb Gel has healing properties. These healing properties appear to be the same as those of a Fireworm Queen's Venom, meaning that they can be consumed by Stoker Class dragons in need of reigniting their flames for the same effect. Therefore it is possible if not likely that the Queen's venom contains doses of Firecomb Gel.


Average Fireworm[]

Small Size[]

The Fireworms' main weakness is their miniature sizes and inability to cause serious harm, often resulting in their abuse and usage as sources of entertainment by being tossed around and led to burn things with their body heat.


As mentioned in Verdigriff's description, average Fireworm larvae can be burned to death through consuming certain alchemical combinations. Consuming these combinations will reduce the dragons' bodies to cinders. Also like many other dragons who live in a pack, a single Fireworm can be defeated with less effort.

Vulnerable Eggs[]

It is shown that the Fireworms eggs (Firecomb) don't explode unlike other dragon eggs, because otherwise Vikings wouldn't be around to be bitten by the babies. Because of this, it is likely that the eggs would be vulnerable to being stolen or attack by either other dragons or non-dragon predators.

Pack Dependency[]

Average Fireworms don't only stick together for strength in numbers they also do it to keep each other warm with their body heat as a single one can keep their body heat going for a while but over time if it doesn't come into contact with the pack mates then their body temperature and glow will get weaker until it dies. And if even one goes missing the whole flock will search for them.

Fireworm Queen/Princess[]

Since Fireworm Queens do most of the work around the nest and are singly in charge of the defense, they cannot stray far from it, since doing so would risk the welfare of the nest. The Queens are also the only dragons in the nest capable of defending it, thus taking over a Fireworm nest is not too difficult for strong dragons or dragons who hunt in packs, such as Cavern Crashers or Changewings.

As mentioned in the Plain Fireworm Queen's description, average Fireworm larvae can only be turned into Queens by consuming Drottning, meaning that new Fireworm hives can only be spawned through this method. The process of average Fireworm larvae receiving Drottning occurs so infrequently that Fireworm hives are uncommon in nature, which could cripple the species. However, the massive amount of Fireworm larvae born in any one hive could counteract the effect of the lack of hives in the wild.

As mentioned in the Enhanced Fireworm Queen's description, Fireworm Queens can be contained if placed in cages that resist heat.

Behavior and Personality[]

The behavior of average Fireworms is vastly different from that of the Queen.

Average Fireworm[]

Fishlegs: "When Fireworms migrate, they send out scouts to see if their migration route is safe. If this is a stop along that route..."
Astrid: "An entire flock of Fireworms could be coming through here."[src]
  — Discussing the influx of Fireworms on Dragon's Edge  

These dragons are often found in large groups. This makes them extremely dangerous. They are even remotely aggressive, occasionally clinging to potential enemies. Fireworms usually wander away from the nest and live normal lives, often in other islands, but regularly return to their nest to replenish their fire and contribute a portion of their gel to the nest stocks. Fireworms tend to set surfaces they walk on and touch on fire, often causing forest wildfires. They might do this to defend themselves from predators.

Strangely enough, average Fireworms are afraid of fire. As shown in "Portrait of Hiccup as a Buff Man", when Toothless blasted at them, they started to back off. The Queen, however, is not. In the episode "Race to Fireworm Island", when Stormfly blasted the Queen, she stood firm and kept fighting.

As shown in the episode "Reign of Fireworms", massive Fireworm colonies migrate from island like birds and other animals do in the real world. They usually send Fireworm scouts to make sure the route is safe for passage. It is unknown why the Fireworms have to migrate or why Fireworm Queens have not been seen migrating. It is almost certain the Queen joined the migration during previous occasions as Smidvarg and the Gang where able to form a Fireworm Queen when attempting to redirect the migration. The reason why Fireworms migrate might be the same reason why birds migrate, to escape the cold winter months of Berk.

Fireworm Queen/Princess[]

Usually Fireworms make their homes in dark caverns with series of complex tunnels. Fireworm Queens are very protective of their firecombs of gel and eggs will chase down anything that tries to take it, or fight to the death to defend them against intruders. As she is a mother, the Queen has a devoted, discreet nature even on rage to take back her firecombs, and being highly intelligent as being capable of conjecturing the intruders' motives and objectives. She is also intelligent enough to know when she is unable to defend her nest from intruders, and seek help from her friends as shown in "Crash Course".

Despite their aggressive nature (to protect their nests), they seem to know if another dragon's fire is worn out, and are kind and sympathetic enough to reignite other dragons' firepower with their venom (only species of Stoker class receive benefits). This may well be a natural instinct for the species.

It would appear that the Fireworm Queen does most of the work in the nest. She produces most of the Firecomb, which she then molds to form the structure and cells of the nest. She also produces a grand part of the liquid Firecomb Gel which she stores in the cells. She also lays all eggs, and cares for the hatchlings. The Fireworm Queen constantly cleans and repairs the nest and cave entrance, and guards and protects it at all costs.

Fishlegs theorizes that uniquely colored Fireworm Queens such as Royal Fireworm may have significance in social hierarchy amongst these females.

As mentioned in the Plain Fireworm Queen's description, Fireworm Queens are an integral part of the ecosystem of boreal forests, as the heat from their bodies generates periodic forest fires that help to rejuvenate the soil.


Average Fireworm[]

Though average Fireworms have never been seen trained specifically; they are mostly used as toys or sources of destruction by Ruffnut and Tuffnut, mostly due to their small sizes and powerful body heat. They have, however, been utilized as a light source by certain tribes in several occasions in some episodes such as "Last Auction Heroes". They are placed in a glass lantern and carried around.

Fireworm Queen[]

Fireworm Queens are naturally highly aggressive and territorial which makes them rather hard to approach mostly due to them having to protect their nests and young. However, once trained they show their very gentle and benevolent side, protecting their trainers like one of their own. To train one show it you are gentle and responsible and pose no threat to the welfare of the nest, and help her fulfil her duties around the nest, especially tending to her young. Once you appear as no threat, the Queen will accept and respect you, and even seek you for aid.

Comparative Statistics[]


Dragons: Riders of Berk[]


In "Portrait of Hiccup as a Buff Man", the gang was searching for the fabled Hamish Treasure, Hiccup, Astrid, Snotlout, Fishlegs, Ruffnut, Tuffnut, and their dragons found themselves trapped in a cave. While searching for a way out, they found a large, dark opening. Entering, they realized that the "floor" was moving. Toothless lit the room, and they found thousands of little Fireworms bustling about in a shallow pit. They found multiple pedestals in the heart of the nest, and the dragons frightened/fought the smaller reptiles off until the kids can found a way out.

In "Gem of a Different Color", they also make a small reappearance when Tuffnut tried to jump into a pit full of Fireworms while holding a Changewing egg which he still thought was a "Stone of Good Fortune," thinking the stone wouldn't let Fireworms burn him, only to be saved by Stormfly.

Dragons: Defenders of Berk[]

Hiccup-toothless-how-to-train-your-dragon-1 Main article: Snotlout's Fireworm Queen

In "Race to Fireworm Island", Fireworms are explored more thoroughly. When Hookfang falls sick due to exhaustion, the Riders read about how Fireworms can reignite the dying flames of a Stoker Class dragon. Hence, they round up all the Fireworms on Berk, which prove to be ineffective.

After the twins, while playing with the Fireworms, realized that Fireworms glow brighter when closer together, the Riders utilize this to their advantage to find Fireworm Island. They try to seize some Firecomb gel, only to be chased by the Fireworm Queen and the Riders attempt to take it by force. Eventually, the Queen sees the sick Hookfang and reignites his flames with her tongue, saving him.

Dragons: Race to the Edge[]

Season 1[]

Hiccup and Astrid and their reaction to a fireworm

In "Reign of Fireworms", three years after the end of First Berserker War, thousands of fireworms migrated towards Dragon's Edge. They had to be stopped or they would burn the whole island to the ground. Several attempts were made to stop them, which resulted in failure. However, they were led away by Hiccup, Toothless, and Smidvarg's pack of Night Terrors forming a Fireworm Queen to a barren island near The Edge saving the island from destruction.

Season 3[]

Snotlout's Fireworm Queen 267

Following the migration, the Fireworm Queen's nest came under attack by the Cavern Crasher during the events of "Crash Course". Thus, the queen flew to Dragon's Edge to ask Hookfang, Snotlout, and the other Riders for help to defend her nest against the Cavern Crasher. Snotlout and Hookfang were able to help the Queen defend the hatchlings long enough for Hiccup and the Dragon Riders to reach the nest and together ward off the Cavern Crasher. They eventually team up against the Cavern Crasher and chase it away.

In "Last Auction Heroes", the Fireworms made a short appearance, held captive in lamps. These lamps were promptly knocked over during the escape, and the Fireworms scuttled out.

How to Train Your Dragon: The Hidden World[]

The Hidden World TV Spot 9

Fireworms are among the myriad of dragons that reside in the Hidden World. Soon after entering the Hidden World upon Stormfly in search of Toothless and his Light Fury mate, Hiccup and Astrid encountered a huge swarm of the tiny Stoker dragons as they flew around the around the awestruck duo, who briefly but greatly gazed in amazement at their beauty before flying onward.

Dragons: The Nine Realms[]

Season 1[]

In "First Flight, Part 1", during the prologue showing Hiccup's map of the archipelago, a Fireworm Queen is pictured on it.

Season 3[]

Main article: Glowmer

In "Empty Fireworm Nest", the Dragon Club passed a flock of Fireworms while flying through the Fire Realm. One of them entered Alex's bag and she unknowingly brought it home. Her mothers, Carla and Hazel, were excited by the new discovery and named the Fireworm Glowmer. They planned on studying it, but after Alex pleaded to let Glowmer free, they allowed her to release him. Glowmer was reunited with his flock, and they all flew back into the Hidden World.

Season 8[]

In "The Great Foster Fake-Out", Glowmer along with some other Fireworms were brought from the Hidden World to be safe from Jörmungandr and when the riders had some Rakke Employees foster the dragons Carla and Hazel were happy to foster Glowmer and his siblings, but then took them to the infirmary thinking their glows were dying out. Later when Mr Rakke arrived in the infirmary Carla and Hazel panicked and hid the Fireworms under a box but a few were scuttling around the room but Jun and Eugene managed to hide them with Mr Rakke seeing them, when they left a Fireworm tried escaping but was too late as Eugene closed the door before it could escape.


Dragons: Rise of Berk[]


The Fireworm Princess was made available in this game. However, no average Fireworms were available for the practicality of game mechanics. Individual Princesses and Queens were also released, such as Flashfright and Royal Fireworm. Additionally, Solar Flare is considered a special breed of Fireworm.

School of Dragons[]

Only the Queen was made available in this game as a rideable dragon in 2014. However, regular-size Fireworms appear during the expansion "Return to Dragon Island" on Eruptodon Island. They appear again inside the Hidden World in the "Hidden World" Expansion and "Curse of the Hobgobbler" Expansion. Fireworm Queens appear in residence in a portion of the Hidden World also during the "Curse of the Hobgobbler" Expansion.

Dragons: Titan Uprising[]

The Fireworm Queen was released as a playable species in this game in September 2020. Five characters were introduced to represent the species: Plain Fireworm Queen, Enhanced Fireworm Queen, Verdigriff, Homunculosa, and Fearsome Flamellion.


  • Asterisk-Transparent The official measurements given by DreamWorks Animation do not appear to be realistic when considering the relative sizes the viewer sees within the TV series. Based on the model sheet for the average Fireworm, it should be "7 inches (17.8 centimeters) long". The Fireworm Queen, on the other hand, should be "57 feet (17.4 meters) long".
  • It is possible that the Fireworm's skin is not really hotter than the Sun. This is because when Tuffnut was burned by a Fireworm, it would have burned his hand off if it was hotter than the Sun, which is approximately 10,000 ºF (5,600 ºC) at the surface. It is most likely an exaggeration because Vikings at the time would not have known the temperature of the Sun itself.
  • It could be possible that the Fireworms received their name from a female Monstrous Nightmare named Fireworm that belonged to Snotface Snotlout.
  • Fireworms are the only dragon with noticeable gender differences.
  • It is possible that Fireworms are based off Glow-worms and Red-Hot Itchyworms, as they look similar and have very similar attributes.
  • In "Portrait of Hiccup as a Buff Man", it is stated that the Fireworm's skin burns hotter than the sun. The Deadly Nadder's flame is supposed to burn with the heat of the sun, so logically touching a Fireworm should be hotter than being hit by a Deadly Nadder's flame, although it is likely they use a less intense heat normally.
  • Fireworms are inspired by fireflies (their ability to fly and their glow), fire-ants (their biting exchanged with heating their skin) or bees (since they live in colonies and have a queen and produce honeycombs replaced with firecombs).
  • Overall, the Fireworm Queen slightly resembles the Yinglong, like the Grapple Grounder, but the Fireworm Queen's features are more suiting to the Yinlong than those of the Grapple Grounder; it is golden colored, has unnaturally powerful (and hot) fire, and is generous and intelligent.
    • The smaller Fireworms are also very similar to the mythological Pyrausta, a tiny insectoid dragon that dwelled in fire.
  • The Book of Dragons in Rise of Berk states that the Fireworm Queen is 500 times larger than the normal Fireworm.
  • Strangely, in School of Dragons, the player can choose a gender for the Fireworm Queen, either male or female, despite it being the only female of the species.
  • The Fireworm species have a slight similarity to the Flightmare. For example, they both have a hostile attitude when it comes to their food (for the Fireworm, it's the honeycomb; for the Flightmare, it's the glowing algae). They also both have a certain food or consumable attributed to them that also glows.
  • In real life, there is a type of animal called the "bearded fireworm" (Hermodice carunculata), a species of marine bristleworm with the ability to inject a powerful neurotoxin that can lead to nausea and dizziness, which is quite the opposite of the Fireworm Queen's curative venom.
  • Fireworms are very similar to Fire Salamanders in The Spiderwick Chronicles books.
    • Both are very small.
    • Both can catch on fire and are extremely hot.
    • Both are worm-like creatures.
    • Both have multiple legs.
  • The Fireworm is the first and only dragon species to be introduced in the TV show that was later brought into a feature film.
  • It is possible that the Fireworms in How to Train Your Dragon: The Hidden World are based off earlier concept art of the species, as they both have four pairs of legs and spikes on their backs. The only difference is that the concept art has a tail that splits in three.
  • Fireworms had to be recreated in higher resolution for the third film, which explains why they look different than their series counterparts.[1]
  • The TV series version Fireworm has the most limbs of all the dragons in the franchise, with a total of 12 (2 wings and 10 legs). In the film, however, it has 10 limbs (2 wings and 8 legs).
