Viggo's Flightmare

Viggo's Flightmare is a Flightmare that appeared in Race to the Edge, in the episodes Maces and Talons Part I and II.

History
This Flightmare lived somewhere near Dragon's Edge, possibly on Algae Island. Heather tracked it for months, before she pretended to join Dragon Hunters. When Viggo wanted to capture it, Heather gave him the information and later made an ambush plan with Hiccup. At first it looked like the Flightmare won't be captured, but after it landed on the Reaper, the Hunters captured and muzzled it.

Viggo used the Flightmare later to freeze Hiccup, unlock the Dragon Eye and as a distraction for his escape. Later the Flightmare was released and it flew to an unknown place.

Appearance
This Flightmare is almost identical color as the Hofferson's Bane, but doesn't glow that much, and appears to spray much more mist.

Personality
This Flightmare appears to be more aggressive, teritorial and intelligent, as it attacked the Hunters, regardless of the consequences, and it sprayed Ruff and Tuff with algae to look at them as food. Also, it chased them around the island while shooting mist, not waiting for a direct hit.

Abilities
Glow: it glows when it eats the algae, and it can use that as an advantage

Shooting mist while flying: Unlike the Hofferson's Bane, this Flightmare chased Ruff and Tuff around while its mouth was opened, leaving a trail of mist in the air.

Relationships
Hiccup: Although it didn't spend much time around him, it was shown that it is very agressive towards him and tried to attack him multiple times.

Viggo Grimborn: After Ryker put the bucket with algae in front of the cage, Viggo pushed it inside, allowing the Flightmare to eat. He said that it must be treated with respect, although he obviously didn't mean that, especially when he muzzled it and used it's mist to unlock the Dragon Eye. Flightmare also wasn't friendly, as it roared at him after he gave it the bucket, and it narrowed its eyes towards him.

Trivia

 * It is possible that this Flightmare is actually Hoffersons Bane, as it was never told where did it ended.
 * This Flightmare doesn't have pupils in its eyes. If you look the Hofferson's Bane closely, you will se pupils.
