Screaming Death

The Screaming Death is a new dragon that is advertised to appear in the trailer of Dragons: Defenders of Berk chasing Hiccup and Toothless.

Description
The Screaming Death is possibly a cousin to the Whispering Death, as they closely resemble each other. However, the Screaming Death is white and has  large red eyes and longer and more massive body from the Whispering death. It also has three rows of teeth, but they are aligned differently than those of the Whispering Death and it has a chin reminiscent of the Seadragonus Giganticus Maximus.
