Scuttleclaw

The Scuttleclaw is a Sharp Class dragon that first appeared in How to Train Your Dragon 2. It has also made an appearance in Dragons: Rise of Berk and School of Dragons.

Official Description
"A hyperactive powerhouse of the Sharp Class. It's extremely difficult to control, but it's a hard worker when it put its mind to it. The Scuttleclaw is a hyperactive terror in battle, moving almost too quickly for opponents to see."

- Dragons: Rise of Berk

"As you may know, the Bewilderbeasts are very powerful dragons that take control over all dragons...Did I say all dragons? I meant to say all dragons except for one...THE SCUTTLECLAW! You might be fooled, but underneath all that cuteness, are little trouble-makers, waiting to cause more mischief. The Scuttleclaw’s behavior does not sit well with the Bewilderbeast, and with lots of rage and anger, the Bewilderbeast capture the playful Scuttleclaws. After being trapped in the Dragon Den under the Alpha's watchful eye for a couple days, the Scuttleclaws found a way to escape and found their way into the School of Dragons! We believe that having the Scuttleclaws join us on campus will teach them how to obey and respect other people, even though their cuteness might fool you. Since you all are experienced, brave Vikings, here is your chance to train and grow your own Scuttleclaw to make them into the dragons they deserve to be! So make your way to Johann’s Trading Post where you’ll find all new FRESH Scuttleclaw eggs, ready to be hatched and trained!"

- School of Dragons

Egg
Scuttleclaw eggs are spherical, with obvious scales. Most eggs are a blend of two colors, one dominating the top and the other, the base.

Hatchling to Adult
It resembles a cross between a Deadly Nadder and a Hideous Zippleback. It's head is similar to a Zippleback's, and its body, legs and feet are reminiscent of a Nadder's. It has spines like those of a Zippleback too, and has a long tail. Scuttleclaws come in a large variety of colors (green, purple, reddish-brown, yellow, etc.).They also have a horn on their nose.

Titan Wing
These Titans have dark green bodies and brown spots all over their wings. It looks more ferocious and has larger, longer dark orange spines on its back. Their face is brown and has some bumps. With broad feet and sharp claws, the Scuttleclaw Titans resemble Deadly Nadders.

Strength and Stamina
Even for infants, Scuttleclaws have proven to be quite powerful. They were able to carry heavy Vikings such as Gobber and Fishlegs. Also, these infants can fly for a very long distance from their home all the way to Berk, carrying heavy riders and like to show off their stamina.

Fire Type
Scuttleclaws have green fire, though they haven't been seen using it as of yet. According to School of Dragons, Scuttleclaw fire is based on copper.

Speed
In Rise of Berk, Scuttleclaws are also described to be incredibly fast dragons which move too quickly for opponents to see.

Bite Strength
They show to have a strong bite, as one of the babies were biting Toothless' tail. Also, when they grown up into adults, their teeth get bigger, meaning that the adults' bite could be stronger than the babies'.

Behavior and Personality
"We can't fly these things!"

- Tuffnut Thorston

"They're babies! They don't listen to anyone!"

- Hiccup

So far, only baby Scuttleclaws have been seen. As infants, they are mischievous and playful, and listen to no one. Not even a Bewilderbeast can put them under command. According to Rise of Berk, Scuttleclaws are active and playful with seemingly unlimited energy. It is described to be a 'hyperactive powerhouse'. This trait could be, rather eccentrically, one of few countermeasures effective to resist to the kings' dragon controlling. They also enjoy playing with Toothless, though the feeling isn't mutual, as Toothless felt uncomfortable around them.

Scuttleclaws often scatter when they are roared at by larger dragons, such as Cloudjumper. In the games Dragons: Rise of Berk and School of Dragons, you can train your Scuttleclaw to adult size.

How to Train Your Dragon 2
The first appearance of Scuttleclaws was in Valka's Mountain. They playfully greeted Hiccup and Toothless and Valka remarked that they 'listened to no one'. The baby Scuttleclaws then proceeded to disturb Valka's Bewilderbeast after Cloudjumper scared them away. Later, when Hiccup prepared to leave the Mountain, several babies were seen nipping Toothless' ears and tails. After that, the riders rode the baby Scuttleclaws back to Berk when all their dragons were under control as they were only dragons remaining in the Mountain.

Dragons: Rise of Berk
Adult Scuttleclaws were first seen in this game, along with the Titan Wing form.

School of Dragons
Scuttleclaws also became available in this game.

Trivia

 * Adult Scuttleclaws are large in size, as proven in Rise of Berk. The babies are almost the size of Toothless himself.
 * The Scuttleclaw resembles a mix between a Hideous Zippleback and Deadly Nadder, with the personality of a Terrible Terror.
 * Scuttleclaw babies seem to bite a lot, or just nibble when playing around with things, people or other dragons. This was demonstrated with Toothless when a yellow Scuttleclaw was biting his tail. It is most likely a result of the babies teething, much like human babies.

 * The Scuttleclaw is the only dragon whose pupils are always round.
