This article is about something not canon to either the storyline of the TV show or The LEGO Movie franchise.
The Chained Fang is a Skulkinweapon apparently favored by Generals such as Nuckal and Kruncha. It is a flail-like weapon, with a white spike attached to a short silver hilt by a darker silver chain. The fang is said to have come from a dinosaur and enables the weapon to deliver fierce piercing attacks.
Dinosaurs may be gone, but their skeletal teeth still have bite… especially when attached to the end of a roaring, steel chain. The Chained Fang is a dentist’s worst nightmare. It was made to make cavities.
