The Screaming Death

The Screaming Death (the member to a sub-species to the Whispering Death), is one of the main antagonists of the Defenders of Berk season of Dreamworks Dragons.

Appearance
The Screaming Death appears to be a heavily mutated, albino Whispering Death. It is white in color, has large red eyes, a longer and a more massive body and larger tail than a normal Whispering Death. It also has three rows of teeth, but they are aligned differently than those of the Whispering Death, set in a chin reminiscent of the Red Death. Judging by the massive size of what is apparently a hatchling, this albino giant is probably one of the biggest dragons of them all.

Personality
Like the Whispering Deaths that Hiccup has faced before, the Screaming Death is both an incredibly dangerous and rather sinister dragon to contend with. Where as Screaming Death try to avoid the light, due to an ultrasensitivity to it, the Screaming Death at first was attracted to light instead, giving Hiccup a weakness to exploit. It appears though that in their second confrontation, it ignored Hiccup's reflective shield, having grown out of this strange habit. This dragon does not appear to possess any actual pathos towards others (with the exception of its mother) as it destroys entire islands, leaving many dragon colonies homeless. It could be possible that, given it's young age, it simply did not know eany better.

Hiccup later finds out the reason that the Screaming Death is destroying the islands for searching his mother, and sends air mail back to the Academy. Eventually, the Screaming Death's mother is freed by Snotlout and Hookfang, and she and its siblings fly out to meet with it. The Screaming Death gave one last roar of thanks to Hiccup, then left with its family, showing that although the Screaming Death is merciless, it isn't vengeful.

Powers and Abilities
The Screaming Death differs from Whispering Death as its' tunnels are so large that they can cause islands to sink. The scales of the beast are extremely tough, as it is not phased by being hit with a Deadly Nadder spines. The Screaming Death is also able to plow right through massive sea stacks with ease, destroying entire islands over the course of a single day. It also seems to have a mutated maturity cycle and seems to become a full grown adult faster. There is only one in the show so its maturity level is not fully known either.

The Screaming Death gets it name by its incredibly disorienting sonic roar that can affect the flight of other dragons. It is also relatively intelligent, as it did not fall for the refection off Hiccup's shield a second time.

Role in the Crossover
While the show disclosed the Screaming Death as an actual threat, fanfic writers often use the Screaming Death as an antagonist in their stories. Much like with the Red Death, the Screaming Death is often portrayed as a primal force of nature, needing the combined forces of the Big Four and their allies in an effort to drive it away or defeat it.
