As seen in a flashback in Fright of Passage, during the decade's passing of Aurvandil's Fire, the Flightmare attacked Berk. Finn told his niece, Astrid to stay back and he encountered the beast. However, the beast used its paralyzing spray on Finn, which killed or later killed him. These events lead to the shaming of Finn and the Hofferson family, which Astrid planned to right for a decade.
Finn is a tall, buff Viking with a long and neat blonde beard and mustache. He is often seen with a double-horned helmet and often has a stern face. He wears a dark grey tunic with has a layer of chain mail from below his belt.
- Finn's design is based on one of the background characters on Berk.
- Finn is voiced by Brook Chalmers, who is also Production Manager of Dreamworks: Dragons.
- Finn or a character who looks like him makes a few appearances in Thawfest, where he can be seen among the crowd. He is also seen in "We Are Family, Part 1" where he is seen with the council and referred to as "...other scary looking Vikings"
- It is unknown whether Finn really died, considering he has appeared quite a few times as a background character. However, it is possible they just used a background character for Finn's design and that he is truly deceased. Brook Chamlers claims he didn't survive his encounter with the Flightmare.
