Magmar is a relative of the Twins, mentioned in several episodes of Dragons: Race to the Edge.
- "I, Magmar Thorston, hereby claim this island in my name and the name of all my family present and future, forever and ever.""
- ―Naming stone as read by Hiccup
The twins discover the Claim stone along with the other Dragon Riders, leaving the twins to believe that they own the island and rule as chiefs.
- "Oh, my Thor! Wasn't he the one who could pass an entire cod through one nostril?"
End of Life
In the episode, "No Dragon Left Behind" when Stormfly appears to have been poisoned by a Slitherwing and believed to be dying, she starts to act bizarre, which reminds the Twins of when their Great Uncle Magmar was dying and going though the stages of grief. At the time of his death he had lost both arms and one leg, and in a rage, would chase people and try to bite them. He also refused to eat, and eventually accepted his fate and died, which the twins remember as the most boring part. It was the twins story about Magmar that made Astrid realize that Stormfly wasn't poisoned, but rather she was mourning the loss of her friend, Garffiljorg.
The Twins discuss Magmar's Funeral in "Searching for Oswald... and Chicken". They remember fondly the 'boar d'oeuvres' at the funeral.
According to the Twins in "Reign of Fireworms", Magmar was able to push a cod through one nostril in his nose.
In "Reign of Fireworms", The Dragon Riders discover a naming stone on Dragon's Edge from the Twins' Great-uncle Magmar.
Magmar is mentioned again in "No Dragon Left Behind". The Twins talk about his physical injuries and how he dealt with them.
The Twins fondly discuss Magmar's funeral in the episode, "Searching for Oswald ... and Chicken".
- Unlike the twins, Magmar knew how to spell correctly.
- The story of his death could be a reference to Black Knight in the movie Monty Python and the Holy Grail. When the character lost both his arms and one leg, he gets very angry and still wants to fight.
- He is one of the few Thorstons whose name doesn't finish in 'nut'.
