Niggy is roughly the size of an English Cocker Spaniel, and is still growing. He's a qudrapedial black western dragon, with very smooth and shiny scales. He has two wings that protrude from his back shoulder blades, and two horn-like promenances from his head. Each of his paws have two foreclaws and a "thumb-like" back claw. He has red slitted eyes, and a black snake-like tongue.
"...a small baby dragon named Niggy who loves to eat plants. He canth be quite sweet less he thinkth your finger be a stick."
- His name comes from a shortened, and latinized, verion of Níðhöggr.
- Niggy is Lukas' only pet, since Vita is considered his cousin.
- Operetta once asked how Lukas can even have a pet when most of his relatives are animalistic.
- A humanized version of Niggy has him in gray and black clothes, with black hair, dark skin, and bright red hair, while chewing on a stick.
- His similarity to the character Toothless from How to Train Your Dragon was a total accident.
