Whispering Death is a very large dragon that appears in the film continuity and exclusive short, the Book of Dragons. This dragon is seen when Hiccup reads the Dragon Manual, and they are classified as Boulder Class. It makes further appearance in the series and is mentioned in How to Train Your Dragon 2.

Physical AppearanceEdit


In the series and in School of Dragons, these eggs are smooth and oval,and of a dark color with even darker spots. In Dragons: Rise of Berk, they looked as if encrusted in a translucent crystal. They have jagged edges and a dark swirl in its middle. This dark swirl could possibly be the curled up embryo of the baby Whispering Death.

Hatchling to AdultEdit

The Whispering Death looks similar to a Screaming Death, with bulging eyes, spiny face and six rows of rotating teeth in its mouth. It has a snake body and neck, similar to a Zippleback, but Whispering Deaths have no legs, only the lower spikes.

Many consider them extremely vicious and often have nightmares after confronting these horrors. Their gaping mouths are full of deadly rotating teeth. Their wings can also be rotated, presumably to aid in the drilling process. They look very similar to the Gulper Eel.

Titan WingEdit

Titan Whispering Deaths are bigger and armed with many more rows of larger, sharper teeth. They have bigger eyes that do not show their pupils, their eyes are encircled by a small white ring. Titan Whispering Deaths are covered with more dark blue spikes. These spikes can be found on their chin, behind their eyes, their neck and on their tail. They have pairs of purple wings with glossy blue edges. Their body is sand brown and the bottom of their chin is faint purple in color.

In School of Dragons, titan Whispering Deaths also appear to have a crown of large, twisting horns around their heard. Their eyes remain white while the area around them turns red and they grow larger. Their spines grow thicker and appear more across their body while getting shorter near the tail. Their wings also gain a blue stripe while becoming more spiky along the edges.


Jaw StrengthEdit

Whispering Death has the ability to use its jaw to travel quickly through solid rock. But despite their powerful jaws, they can't break through metal.

Rotating TeethEdit

They have special ability to tunnel underground with great speeds because of their rotating sharp teeth. As these rows of teeth move backwards, it literally sucks everything in a good range in its path. This is called the Vacuum effect.

Fire PowerEdit

Whispering Death can breathe powerful rings of fire. An immature Whispering Death's fire is considerably weaker than an adult's.

Strength and CombatEdit

These dragons are very strong physically according to Fishlegs, as shown by Toothless' Rival being able to throw Toothless a great distance by using its tail. They are also able to carry the weight of Alvin and Mildew by the tail.

As proven from Toothless' Rival, has proven to be one of few dragons to able to fight against Night Fury.

Speed and AgilityEdit

Their body, being long, is extremely flexible, and to fly faster, it simply spins its body in a circular motion at a higher rate. With its long, thin body, the tail often makes a whip-crack noise.

Spine ShotEdit

Whispering Deaths are able to shoot their spines just like a Deadly Nadder, which grow on the head and along the length of his body. According to Fishlegs they can shoot spines from any part of their body.

Tunneling Edit

They have six inner rings of sharp teeth that can be rotated in opposite directions which helps the dragon to make tunnels. When these teeth move, they make a terrible and eerie noise that sounds like whispering. Hearing "The Whisper", together with the ground rumbling, are often the only two warning signs that a Whispering Death is coming from underground tunnels if it is not near the surface, throwing earth and rock. Toothless could detect the presence of one from Hiccup's bedroom, which is above ground level.

Endurance and StaminaEdit

Whispering Deaths have high defense, being a Boulder Class dragon. They can take many attacks from their enemies as Toothless' Rival was able to fight against Toothless and even getting hit by two large boulders from catapult in the face.

Senses and ImmunityEdit

It's possible the Whispering Death's sense of smell is strong enough to track down its enemies as Toothless' Rival was able to find Toothless in Berk.

Apparently, it has an immunity to the effects of conventional Dragon Nip. When Hiccup tried to use the Dragon Nip to stop an attacking Whispering Death, sniffing it just made the dragon sneeze.


The Whispering Deaths shown have great intelligence as the babies were able to work together as a team to be able to pick up the Screaming Death and Toothless' Rival was able understand that Toothless is unable to fly.

Hunting and FishingEdit

Whispering Deaths are shown to hunt from underground. It is quite possible they use tunnels to trap their prey so they can hunt on their own terms. It is also implied that the Whispering Death can swim, as the hatchling Whispering Deaths were shown to bring fish to their wounded Screaming Death sibling.

Behavior and Personality Edit

Whispering Deaths are extremely dangerous, like most other dragons, and are able to chew their victims after their ingestion, using their six rows of rotating teeth. They usually live in underground tunnels they burrow themselves, using a burrowing attack against oncoming enemy/prey.

The Dragon Manual once said that they were extremely dangerous and must be killed on the spot. Nevertheless, despite their fearsome reputation, they want their teeth to be brushed. In What Flies Beneath, Fishlegs noticed that a Whispering Death's eyes were sensitive against direct sunlight, which is why it spends most of its time underground.

When Whispering Deaths find intruders in their tunnels, they will forcibly eject them from the nearest pit. This was done to Bucket, but later, when he did the same to Hiccup, he also tried to kill him, pursuing him even above the ground; this may be because although Bucket had simply fallen in, Hiccup was caught running along its tunnel system. Perhaps the dragon believed he was deeply invading his territory or he smelled Toothless scent on Hiccup thinking they are allies.

Whispering Deaths are known to be more dangerous in their infant stages, in contrast to their adult forms. They say that they have less control over their rotating teeth and spines, and are described to be "out of control saw blades." Young Whispering Deaths are known to be extremely territorial of their homeland, "claiming it as their own."


Whispering Death hate sunlight so they spend their time underground. Although their teeth can break rock, they can not break through metal plating.


Whispering Deaths are almost untrainable. They are very destructive and aggressive in nature, attacking anything in their way and is generally feared by other dragons and humans. The only way to train a Whispering Death would be to capture it and take your time until you eventually gain its trust or raising one as a hatchling.


  • According to Astrid, the Whispering Death weights about 2,500 pounds.
  • According to Gobber, a Whispering Death knows only one thing: killing. In fact it is kind of true. The Whispering Death that appeared in "What Flies Beneath" was untrainable, and one that appeared in the finale was extremely aggressive towards Hiccup and Mildew. If this saying is true, then it helps to explain why Alvin could train his Whispering Death. Like most dragons and riders, they share personality traits.
  • A Whispering Death's diet includes cattle, sheep, and yaks, though it also seems to eat humans, or at least those who invade his territory. It is implied they are able to fish.
