Night Light

The Night Light is a hybrid between a Night Fury and a Light Fury which will appear in How to Train Your Dragon: The Hidden World.

Physical Appearance
The Night Light has an appearance similar to bothe a Night Fury and a Light Fury, since they are closely related species. They appear to have small fins on their back, like a Night Fury, lacking the single spine of the Light Fury. Their tail fins are also like a Night Fury's instead of a Light Fury's. They have four ear-like appendages on their head, like a like a Light Furu, instead of six, like a Night Fury. They are black and white, without a specific pattern.

How to Train Your Dragon: The Hidden World
Toothless and the Unnamed Light Fury become mates and have three offsprings, which Hiccup names Night Lights, as a combination between the names of their parents' species.
