Night Lights

The Night Lights (that is commonly known by her specie's name as she wasn't given a [official] name) are Toothless and his mate's three hybrid hatchlings of both Night and Light Furies, who appear in the end climate of How to Train Your Dragon: The Hidden World.

Weapons
As dragons, the Night Lights lacks the means to wield weapons properly and relies on their claws, teeth and the fire power of their plasma blasts.
