Grimmel the Grisly

"I am the Night Fury killer."

- Grimmel

Grimmel the Grisly is the main antagonist of the film How to Train Your Dragon: The Hidden World. He is a dragon hunter who believes that dragons must be exterminated, and is responsible for bringing the Night Furies to near extinction, leaving Toothless the last one of his kind.

Dragon Hunting
Prior to the events of the third film, Grimmel hunted down all Night Furies known to be in existence. Toothless is the only one he has not killed, possibly because he had been with Hiccup and therefore sheltered.

Physical Appearance
Grimmel is a tall, slender man with gray hair, pale skin, and hazel eyes. He wears leather armor, brown pants, greyish-brown boots, and a hooded jacket.

Personality
"Nothing's accidental when it comes to old Grimmel. He lives for the hunt. To get inside the mind of his prey, to control its every choice. It's all a game to him."

- Eret's assessment of Grimmel's character

Grimmel is a seasoned dragon hunter who lives for the thrill of the chase and anticipates every course of action that his prey will take. He is patient, determined, and waits for the right moment to strike.

Grimmel has been described as "the darkest threat" to the Dragon Riders. He holds great prejudice towards dragons and is of the firm belief that they must be either imprisoned or eliminated. Any alternate ideas that involve coexistence are unacceptable to him, as he believes that dragons and humans simply cannot live together.

Abilities, Skills, and Talents
Dragon Hunting: Grimmel is a substantially experienced hunter who knows how to track down his prey and anticipate their actions.

Dragon Commanding: Grimmel managed to successfully drug six Deathgrippers and trained them to become vicious killers that obey his commands. He trained them through unknown ways to answer to his whistles.

Dragon Riding: Grimmel is able to ride the Light Fury without any difficulties after drugging her with Deathgripper venom, until he is knocked off her back by Hiccup.

Toothless
Grimmel has claimed to have hunted down every Night Fury except for Toothless. This causes the latter to become the hunter's most coveted trophy, particularly since capturing Toothless simultaneously allowed him to capture the rest of Berk's dragons.

"You are nothing without your dragon!"

- Grimmel to Hiccup

Being the best friend of his ultimate prize, Grimmel knows that Hiccup is an obstacle in his hunt and threatens to destroy everything the young chieftain loves if he does not give Toothless up.

Unnamed Light Fury
Grimmel captures Toothless and the Light Fury in his campaign to exterminate all dragons. Later on, Grimmel uses Deathgripper venom on the dragon in order to ride her and control her more easily. Fortunately, Hiccup saves the Light Fury by kicking Grimmel off her.
