Typhoomerang

A Typhoomerang (portmanteau of a typhoon and a boomerang) is a new species of dragon that appears in Season 1 of DreamWorks Dragons: Riders of Berk, the TV Series.

Typhoomerangs have a unique way of flying: they spin (similar to a typhoon/boomerang) at high speeds, zooming through the air. Although, as they fly, they seem to scorch objects around them, making them extremely dangerous.
