Razorwhip

"Razorwhip. Sharp Class dragon. Long, spiny, barbed tail. Very aggressive. Very dangerous. It can use its tail to wrap around a victim and literally squeeze the life out of them. Unless it's in a hurry. Then it just slices you in half."

- Fishlegs Ingerman reading the Dragon Eye

The Razorwhip is a medium-sized Sharp Class dragon that first appeared in Dragons: Race to the Edge.

Official Description
"One single blade of the Razorwhip's tail is as deadly as the sharpest battle-axe. Arguably one of the most dangerous dragons the riders have ever faced, the Razorwhip has an aggressive and deadly nature. It has a barbed telescopic tail that can squeeze the life out of any Viking or dragon, or slice anything it comes into contact with to pieces. It is so dangerous that even the tears from its eyes are poisonous. It is extremely agile and maneuvers incredibly. Its only known vulnerability is its propensity to eat sea slugs. Razorwhips are reclusive by choice, due to extreme mistrust of both humans and dragons. However, those who are able to prove their worthiness to a Razorwhip will have made a powerful friend and ally for life. The first Razorwhip encountered by the Dragon Riders is Windshear, who has teamed up with Heather."

- Dragonpedia

"Try to get on this Dragon's good side... if you can find one. Their toxic breath and razor-sharp tail make them dangerous from top to bottom! Don't get too close! This Dragon will breathe toxins on its enemies. Talk about bad breath!"

- Dragons: Rise of Berk

"After a day filled with cunning adventures, Trader Johann and his crew decided to stop off at their favorite place, the Cove. They heard some strange sounds but didn’t think anything of it. Suddenly, the beautiful and sunny skies began to darken. The strange sounds became louder and louder. One of the explorers that had come along to help Trader Johann restock his store was able to make out a tall and robust dragon with widespread wings. As they caught it thrusting its metal tail of spines against the nearby trees as it walked by, they realized that it was a Razorwhip, one of the most deadly known dragons on Berk. The team of explorers knew that they must not fall prey to this dragon’s poisonous tears. They quietly snuck around the perimeter of the trees, where in the deep and dark corners of the island's shores, they found a massive nest of eggs. They packed a number of them away before taking flight back up to the main part of campus, bring their fierce companions to Johann's Trading Post! And now are you ready to train the most daring dragon yet? The Razorwhip has shot its way through campus and is available now for you to raise and add to your stables!"

- School of Dragons

Egg
In School of Dragons, the Razorwhip egg has numerous bands of black and silver on it. It is a regular oval and appears to be rather shiny.

In Dragons: Rise of Berk, the Razorwhip's egg appears to be shiny bronze. It is slightly triangular shaped and features several plates layered on it that make it seem sharp. It resembles a pine cone in a way.

Hatchling to Adult
The Razorwhip is a four-legged dragon with a long, slender neck, as well as metal-like, reflective scales. It has a long ledge on the top of its snout and a short, stumpy one on the bottom. Its body is covered in metal armor with two talons on each foot. The Razorwhip appears to have a short, spiky sail and has spikes all along its wings. Its teeth seem to wrap around the edge of its mouth, and it has high ridges over its eyes that resemble eyelashes.

Titan Wing
Titan Wing Razorwhips are very to normal Razorwhips, though they are darker in color, larger in size, and have red eyes. In School of Dragons, they have lighter, almost white coloration. They also have extra spikes going down their neck and back.

Abilities
Arguably one of the most dangerous dragons, the Razorwhip has an aggressive and deadly nature. In addition to the dangers implied by its name, Razorwhips possess a barrage of alternative defenses and skills, such as lacrimal toxins (poisonous tears) and extreme precision and maneuverability in flight.

Speed and Agility
Razorwhips have been shown to be quite acrobatic dragons as their metal-like bodies have no lack of flexibility at all. They are able to twist their neck and their tail as well. They can also tie themselves into a knot, according to Bucket.

It was demonstrated by Windshear in "Have Dragon Will Travel, Part 1", that the speed of a Razorwhip is fast enough to be as near as a Night Fury.

Strength and Combat
The Razorwhip has shown to be able to pull a tree off the ground quickly and drag it in the air at full speed without any struggle. They were described to be as powerful as a Typhoomerang, as Windshear fought one. But it is unknown who had won, and Windshear was badly wounded. It is described to be as strong as a Typhoomerang meaning they could lift possible amount the weight that Torch has done in the past as proven to hold the weight of Shattermaster, Dagur, and Heather no sign of a struggle as she was still flying very fast.

The Razorwhip from the Dragon Arena was shown to be able to fight against Toothless the Night Fury as it was able to leave a scratch on his foot fast enough before Toothless could react to dodge but soon was defeated in short battle from intelligent battler.

It is also revealed by the Wingmaidens that young Razorwhips are strong enough to carry humans while flying.

Whip-like Tail
The Razorwhip has a telescopic tail which can fold out of itelf and extend spikes from all angles and can be used as a whip. This tail is also extremely sharp, seen to be able to cut wood and rock.

The rest of their body is quite flexible. The Dragon Eye indicates that a Razorwhip can use its tail to squeeze the life out of its victim. Unless it's in a hurry, then it slices you in half.

Prehensile Tail
The razorwhip has a prehensile tail, which can be used to grip objects and makes the dragon even more dangerous.

Barbs
Like Deadly Nadders and Whispering Deaths, Razorwhips can shoot spines from their tails. They are incredibly sharp and can pierce through wood and stone with utmost ease. The sharpness of the barbs is compared to that of a Speed Stinger's tail by Fishlegs.

Firepower
The Razorwhip's breath can burn the flesh off a human from a hundred feet away. The intense heat of the Razorwhip's fire can be shown from its bright blue color. However, it might have been an exaggeration from the Dragon Eye, because the Twins, Snotlout, and Barf and Belch were able to survive at a very close impact. After being shot, the fireball or beam will hit its target and then explode.

Lacrimal Toxin
Razorwhips are said to have extremely poisonous tears, although it has never been shown.

Endurance and Stamina
Heather mentioned that the Razorwhip is able to withstand the attacks of a Typhoomerang but can take serious damage from large opponents, and Windshear needed intense treatment to make a full recovery.

Windshear showed signs of pain when Shattermaster the Gronckle attacked her under her belly, which is most likely the Razorwhip's weak spot.

The Razorwhip has amazing stamina as it is able to travel high speed on a short to mid-distance as it was being chased by a Night Fury like Toothless and was still able to travel.

Baby Razorwhips are shown to be able to carry adult humans for long distances and at high speed.

Intelligence
The Razorwhip is extremely intelligent, knowing commands and even has the knowledge to distract a rider (such as Windshear did Hiccup and Toothless) before hurling a tree towards them. They also seem to be able to learn who they can trust.

Curling Up
It is mentioned in Rise of Berk that Sawtooth can curl up into a ball and roll into its enemies in a similar manner to a Catastrophic Quaken, which is possibly an ability for the entire Razorwhip species.

Sea Slugs
The Razorwhips' love for consuming sea slugs can be used against them, giving its opponents a hint of their location (somewhere with an abundance of sea slugs).

Belly
The belly of the Razorwhip could be a weak spot as proven by Shattermaster when he hit Windshear's underbelly with his clubbed tail, which caused her to fall and left her stunned for a moment.

Tail
If a Razorwhip's tail is chained up, it will be unable to use it.

Hatchlings
Razorwhips are born blind and are very vulnerable. Mother Razorwhips provide nurturing but are often attacked and killed by roving male Razorwhips. This makes a huge impact on their population, to the point that the Wingmaiden tribe steps in to successfully rear the young until they attain sight and are larger.

Behavior and Personality
Male Razorwhips, unlike most dragon parents which are incredibly protective of their young, commit filial infanticide, a biological phenomenon when the adult eats its own offspring. This cause the Razorwhips to nearly go extinct a thousand years ago, only to be saved by the Wingmaidens, as revealed in "Snotlout's Angels". As such, female Razorwhips are aggressive to all males, no matter its breed or species.

It is also shown to be highly intelligent, distracting Hiccup before hurling a tree towards them. The Razorwhip also has a sense of humor and is somewhat vain, taunting its opponents when they are defeated.

Razorwhips are said to love eating sea slugs. Razorwhips are reclusive by choice, due to extreme mistrust of both humans and dragons. They are shown to be highly territorial and protective, even picking up fights with the most docile of dragons. In Dragons: Titan Uprising, some Razorwhips such as Hailfate have learned to carve a hole in the Arctic ice and spear sea slugs with their tails.

However, those who are able to prove their worthiness to a Razorwhip will have made a powerful friend and ally for life. Windshear, for example, is incredibly protective of Heather and will stop at nothing to protect her, even if she is riding another dragon.

Mating
Judging from one of the symbols from the Dragon Eye showing two Razorwhips curling around each other, Razorwhips act much like constrictor snakes when mating. Because Razorwhips are solitary and often will attack another one that they see, how they mate is a test of strength. Both Razorwhips must try to squeeze the other one into submission, in the male's case if he wins, he gets the right to mate. But if the female wins, the male must leave.

Training
These aggressive dragons are hard to train, due to their reclusive nature. However, trusting the dragon, and showing that you are worthy of its trust will win over this dragon's heart. Heather, for example, nursed her to health when she was badly injured and made use of the dragon training methods the other riders taught her, presumably placing her hand against its snout to form a bond via a physical bond. While the dragon is still somewhat hostile to many others, it is incredibly close to her.

"Both dragons and Vikings are quick to get out of the way of Slash-Dasher and her stinging temper. This unruly and often boorish beast refuses to cooperate with anyone besides her trainer or Fishlegs. The secret to winning her over is by sharpening her tail — if she lets you that close. Few have seen this secret side to Slash-Dasher. In private, she will curl up like a great ironclad kitten while her tail is being filed."

- Slash-Dasher's description in Dragons: Titan Uprising

As mentioned in Slash-Dasher's description in Dragons: Titan Uprising, sharpening a Razorwhip's tail is another way to train the species.

Season 1
The first indication of the Razorwhip was during Bucket's recount of a rogue dragon that attacked his fishing boat in "Have Dragon Will Travel, Part 1". Traumatised by the experience, Bucket described the dragon and screamed as a sketch of the dragon was produced. After examining the boat and research with the Dragon Eye, the gang deduced it as the Razorwhip and headed to Sea Slug Island. Over there, each of the Dragon Riders slowly get picked off by what seems to be the rogue dragon and rider duo. Hiccup and Toothless quickly spot it when patrolling the cliffs. They give chase, only to be met by a fierce opponent. After being tricked into a near-death experience, they exert all their force and take it down. The Rider then reveals herself as Heather and the dragon as Windshear. After a series of apologies and clarifications, she begins to boast about the Razorwhip's abilities and how she trained it. The duo then appeared in several other episodes.

Season 3
In "Stryke Out", the Fighter Razorwhip was first seen along with the other fighter dragons in a Dragon Fighting Arena. Later, it fought Toothless but lost when the Night Fury outsmarted it. After Hiccup tamed Whip-Slash and Steeltrap, a few Hunters brought the dragon inside and put a manacle tight on its tail. Hiccup tried to melt the manacle with the help of the other dragons but failed. When the Riders came to the rescue, Heather told Windshear to cut the manacle and they broke out. The Razorwhip destroyed the doors with its fire. It grabbed a hunter that mistreated it, threatened him and let him fall in front of the Triple Stryke. Then, the Razorwhip and the other dragons flew free to an unknown location.

Season 5
The history and lifecycle of the Razorwhip are revealed in the episode, "Snotlout's Angels".

Season 6
During the Grand Transition celebration of the Wingmaiden Tribe, several Razorwhip babies choose their Wingmaiden, that has to take care of them. One of the babies chooses Ruffnut, much to her surprise. Tuffnut names the baby Wingnut and helps his sister take care of the Razorwhip. In the end, Wingnut acknowledges the fact that he can't stay with Ruffnut forever, and accepts Atali as his Wingmaiden.

Dragons: Rise of Berk
The Razorwhip appeared in Rise of Berk quite a while after the first episode with the Razorwhip was aired. The producers included Windshear and an exclusive Razorwhip, Thorstopian, a stockier group of individuals discovered by the Twins.

School of Dragons
The Razorwhip became available as a trainable dragon in 2015. In 2016, a Titan Wing form became available to upgrade to.

Trivia

 * The Razorwhip looks strikingly similar to another Sharp Class dragon called the Windstriker. This might be coincidence, or maybe the two species are somehow closely related.
 * Razorwhips have the strongest armor of all the Sharp Class dragons
 * The Razorwhip's bright blue fire breath is consistent with the extreme heat it is said to burn with, as blue fire is much hotter than red or yellow fire. It may also take inspiration from the atomic breath of the famous movie monster Godzilla.
 * In the books, there is a dragon called the Razorwing, possibly part of the Razorwhip's inspiration. Both species have distinct poisons; Razorwhips have tears and Razorwings shoot darts from their mouths.
 * The Razorwhip on Hiccup's map has two legs instead of four.
 * The Razorwhip drawing on Hiccup's map looks very similar to the Sword Stealer.
 * In School of Dragons, the Razorwhip lacks the large "eyelash". In Dragons: Rise of Berk, their wings do not have extra spikes at the base.
 * In Dragons: Rise of Berk, it says that the Razorwhip's breath is toxic. This could be an error with its breath getting mixed up with its tears.
 * In real life, males eating the offspring of others would not result in the near extinction of the species.
 * In reality, there are many species of animals in which males kill (and sometimes eat) babies of the same species. This is often done to bring the female back into season so the male can breed with the female, and eliminate genetic competition from other males and perpetuating his own.
