Description
Grim Gnasher from Dreamworks Dragons.
Grim Gnashers are scheming and cunning predators that tend to plot against their prey. Furthermore, they exploit the weaknesses of the old and sick dragons of Vanaheim, a divine funeral ground for dragons to spend their last days. This behavior is likened to that of a vulture who circle weak prey and consume carrion. As Dentinales guard Vanaheim and both the dead and elderly/dying dragons, Grim Gnashers have become their enemies since they are taking advantage of a ready food source.
While the Grim Gnashers appear to be villainized, in a functioning ecosystem, these dragons are an important part of removing weak animals and, presumably, cleaning up carrion, allowing the food cycle to continue, just as real-life scavengers do.
Grim Gnashers work in packs like other creatures such as wolves. There is a pack leader or Alpha, who has a red back and wings to distinguish it from other pack members.
