- "A grip that can peel the beak off a chicken."
- ―Tuffnut saying he was attacked by a mysterious creature called the Lycanwing[src]
The Lycanwing is a supposed mythical dragon species in Race to the Edge.
According to Gobber, a Viking named Kessler had gone exploring into the woods of Berk. He disappeared and was not found. Every year on Kessler's birthday, a dragon would come to his home.
Tuffnut claimed he was attacked by a mysterious creature. Gobber deduced it was a Lycanwing, a dragon that could turn those who it had bitten into dragons. Tuffnut proceeded to lock himself up in a dragon pen to prevent him from hurting anybody
Ruffnut, using Snotlout as a bite-mark matcher, tries to find out what had bitten her brother. Eventually Tuffnut escapes the pen he locked himself in.
Hiccup did not buy the story, but when the lens he and Fishlegs found revealed information on it, Hiccup and Fishlegs headed to Lycanwing Island. There they discovered a statue of a Lycanwing set there to scare people away from two Dragon Eye lenses hidden in the cave.
Thanks to Snotlout, Hiccup found out what had bitten Tuffnut was just a wolf, which had bitten Snotlout too.
- The word "lycan" comes from lycanthrope, another name for werewolf, a mythical creature that can turn humans into werewolves by biting them.
- Ironically, it was a wolf that bit Tuffnut.
- The Lycanwing is one of three "mythical" dragons. The other two being the Boneknapper and the Smothering Smokebreath. Of the three, it is the only one that has no proof of its existence.
- It is unknown why the Lycanwing is in the Dragon Eye, even though it doesn't exist. This could be evidence that it does exist and just hasn't been seen yet. It might also have been a way to scare people away from the island if they ever got a hold of the Dragon Eye, so that they wouldn't find the two lenses in the cave.
- The Lycanwing could also potentially exist on the island, due to the fact that Hiccup and Fishlegs barely explored the cave, let alone the entire island, before leaving.
- It's also possible that the pair of Dragon Eye lenses found in the cave on Lycanwing Island could hold more information on the Lycanwing.
- If this dragon does exist the Lycanwing would likely be in the Mystery Class. It also likely doesn't have an infectious bite, or at least not one as strong as it is in the legend.
- The body shape of this dragon in the Dragon Eye is similar to a Whispering Death. It is possible that it might be a subspecies or just quite look similar.
