Humbangers have two rear legs and a pair of small, but functional wings. They have a large round head with long teeth, especially on the lower jaw. The lower jaw is also arrayed with spikes. Humbangers have a pair of horns on the top of the head and a row of ridges on the center of the head. The tail is long but hefty, and is weighed down by a large mace-like ball at the end. The Humbangers' eyes have no visible pupils, similar to the Whispering Death.
Humbangers have a highly explosive type of fire, and Boast-Roaster is eager to let the flames fly.[src]
In general, Humbangers are friendly and social dragons, often forming groups for mutual benefit. There are some individuals though, that are not as social as the norm, such as Boast-Roaster and the Groggy Fogtrotter. Humbangers also prefer burrowing near the surface rather than deep into the earth, though they appear capable of doing so. They have a diet of rock and prefer gemstones, similar to Snafflefangs, which have an affinity for geodes.
