Orange was a NightWing-BeetleWing hybrid of unknown gender mentioned in The Lost Continent. They were one of Sunstreak's and Clearsight's dragonets, along with their siblings Jewel, Commodore, and Tortoiseshell.
The Lost Continent Prophecy
After she arrived on Pantala and saved the tribes, Clearsight had a vision of her future dragonets. Among them, she saw Orange and described the dragonet as "cuddly." Clearsight thought that Orange was a strange name and figured she should have a talk with Sunstreak about it.
