Grimmel the Grisly is the overarching antagonist of the How to Train Your Dragon franchise.
He is a ruthless, devious, and cunning dragon hunter who believes in the extermination of all dragons and was responsible for bringing the legendary Night Fury race to near-extinction, leaving Toothless the last one of his kind. He won the reputation of a hero and has his eyes set on Toothless and will stop at nothing to hunt the dragon down, putting him in conflict with Hiccup along the way. He is the cruelest, most manipulative, and greatest enemy that Hiccup and the rest of the Dragon Riders had ever faced.
He was voiced by the Academy Award winning actor F. Murray Abraham.
