“ Despite their small size, Grim Gnashers love nothing more than to sink their thousands of teeth into smaller and weaker dragons. Sneaky and opportunistic, Grim Gnashers circle above their injured prey like carrion birds. Even though they hunt in packs, Grim Gnashers prefer to feast on a dragon that can't defend itself, rather than take on a healthy dragon. Yet Grim Gnashers are just as deadly with their long-range attacks. Possessing a shark-like ability to regenerate row after row of sharp teeth, these dragons spit out fiery blasts of fangs with remarkable precision and accuracy. But perhaps the most dangerous thing about Grim Gnashers is their ability to plan and communicate with each other to outsmart their quarry. ”
“ These Sharp Class dragons live off the dragons which arrive on Vanaheim. Using their unique ability to blast razor-sharp darts made of their teeth, Grim Gnashers hunt down sick dragons and the Sentinels who protect this sacred island. While not the friendliest of dragons, Grim Gnashers live in packs and work well with others. The alpha of the group is easy to spot by its red wings and stripes, as opposed to the regular Grim Gnashers’ purple hue. ”

“ The most dangerous thing about Grim Gnashers is theur ability to plan and communicate with each other to outsmart their quarry. They circle above their injured prey like carrion birds. Grim Gnashers fight dirty. They always prefer taking on an injured, helpless, or otherwise weakened Dragons. When together in packs they are not to be underestimated. ”

Egg== Grim Gnasher Egg The Grim Gnasher egg in 驯龙学院 is oval and has a dark color. It has scale-like patterns that are red, yellow and pale pink, similar to the colors of an adult. It is covered in spikes, for defense purposes.
Hatchling to Adult Grim Gnashers resemble 爪滚龙s as they have similar long, serpentine bodies albeit thicker, a small head and four legs. They have three main sets of horns on their heads, complemented by more along their necks and backs. In addition, they have a long nasal horn and a distinct under-bite with small rows of pointy teeth, giving them a sinister appearance. Covered with prominent, iridescent purple scales, they have a paler underbelly but more vibrant coloration on their backs and wings.
The leader Grim Gnasher has purple scales, red stripes on its back and red wings, differentiating itself from the rest of the group.
Titan Wing Titan Grim Gnasher Titan Wing Grim Gnashers, as revealed in 驯龙学院, have similar coloration patterns as the Broad Wing stage — a solid base color with another color along the back. Titan Wing Grim Gnashers have the same body structure as adults but sport larger and thicker spikes and horns. The largest pair of horns on the head is reminiscent of those of a longhorn cow or other bovine.
Abilities Regenerating Teeth Grim Gnasher 66 Much like sharks, Gnashers have the ability to shed and regenerate as many rows of teeth in their lifetime. They are said to have a thousand teeth. Furthermore, they can attack by shooting them in their blasts with incredible precision.
Teamwork and Communication Their remarkable communication skills are the core of their extraordinary teamwork. They are able to plan and communicate to plot against their prey. As such, they tend to hunt in packs and ambush their prey. Similar to the 风刺龙s, the Grim Gnashers have a leader (or an alpha) whose orders they follow.
Speed and Agility Grim Gnashers are very fast and agile dragons that are able to swiftly ambush their prey as well as evading attacks.
Firepower Grim Gnasher's fire As shown in 驯龙学院, along with its teeth darts, the Grim Gnasher is also able to shoot powerful blasts of fire. However, it prefers to use its teeth, as they require less energy and have a better accuracy than the fire.
Behavior and Personality Grim Gnashers are scheming and cunning predators that tend to plot against their prey. Furthermore, they exploit the weaknesses of the old and sick dragons of Vanaheim, a divine funeral ground for dragons to spend their last days. This behavior is likened to that of a vulture who circle weak prey and consume carrion. As Sentinels guard Vanaheim and both the dead and dying dragons, Grim Gnashers have become their enemies since they are taking advantage of a ready food source.
While the Grim Gnashers appear to be villainized, in a functioning ecosystem, these dragons are an important part of removing weak animals and, presumably, cleaning up carrion, allowing the food cycle to continue, just as real-life scavengers do.
Grim Gnashers work in packs like other creatures such as wolves. There is a pack leader or alpha, who has a red back and wings to distinguish it from other pack mates.
Appearances Dragons: 飞越边界 Season 5 Grim Gnashers are introduced in the episode, "Searching for Oswald... and Chicken". 小嗝嗝 and 鱼脚丝 return to Vanaheim, along with 达格, following up on clues from Oswald's Diary. They encounter the Grim Gnashers there, a predatory dragon-eating species preying on the weak and dying dragons on the island. They also find out that Oswald had made it his mission to assist the Sentinels protecting the ailing dragons from these predators. There was also a diagram of a Grim Gnasher on a wall in Oswald's hut in Vanaheim.
Season 6 Grim Gnashers return in “Guardians of Vanaheim”, not long after Dragon Flyers attacked and incapacitated the Sentinels. The Grim Gnashers make their presence clear after they seemingly kill and devour a Flyer that has been captured by the Dragon Riders while trying to escape with a Dragon Eye lens. The Grim Gnashers then make their move towards the hibernating Sentinels when 悍夫纳特, 暴芙纳特, Barf and Belch start attacking them. Knowing that the Sentinels are the only ones powerful enough to stop the Grim Gnashers, 鱼脚丝 and the Twins have their dragons arouse the guardian dragons by exposing them to the heat of their fire. The plan worked as the Sentinels awaken and drive off the Grim Gnashers once again.

All individuals seen are purple in color, with red backs. They attack the player and Dragon Riders on Vanaheim and appear as opponents in some of the levels of the 'Dragon Tactics' activity.
