The lady night fury I've been doodling for a bit now with the knowledge that Toothless getting a girlfriend is pretty much inevitable. She does look a lot like him since all the night furys probably look about the same just like with the other dragon breeds in the movie. There are subtle differences though like her being dark purple instead of dark blue and having blue eyes instead of yellow-green eyes. Yay fan characters. She needs a name.

Edit: Her name is now Nightfall ^^
