Thunderdrum

  They form pods in a hunt or on migration, and take care of each other and can be compassionate, and these features are similar to those of cetaceans. The Scauldrons also share at least the first of these traits (most so far encountered specimens had not been calm at times), and both of them are whale-like dragons. This dragon is reclusive in nature, living in sea caves and dark tide pools or even in open waters.

They can expel air from their body to swim and being nearly deaf makes it immune to the Death Song's call. They also have an expandable mouth, small legs, two pairs of wings, spines, and a nasal horn. They fancy sea caves and dark tide pools. It is said when a Thunderdrum hatches from its egg, it makes a sound so loud it rattles the sky. As babies Thunderdrums have the strength to be able to drag two young humans on its tail with no sign of struggle. Legend also has it that when the Thunderdrum hatches from its egg, it makes a sound so loud it rattles the sky. When not swelling its body up to yell, Thunderdrums can actually flatten their body by expelling all oxygen from their massive lungs for a limited period of time. 

In this sleeker state, Thunderdrums can better skim the ocean surface or even dive beneath the waves in search of prey. While it's true that Thunderdrums create tremendous amounts of noise, they also possess the ability to cancel out each other's sonic blasts. By modulating its roars to the proper frequency, a Thunderdrum can use its soundwaves to negate an attacking Thunderdrum's bellow, rendering it into a rather calming wave of white noise. This dragon relies mostly on its two sets of wings, one primary and one smaller set to the rear, using them to get around and move through the water like a tornado. These dragons have stubby legs and long, skinny tails. It also has a series of backward facing spikes sticking out of its back. The Thunderdrum's body resembles several marine creatures such as a basking shark, a whale shark, a manta ray, or a baleen whale. Its head somewhat resembles that of an angler fish. Several other dragons share similar head shapes such as the Skrill and the Flightmare. Its wings look similar to those of a Changewing. Thunderdrums have really powerful wings and the spikes on their tails are very sharp. Titan Wing Thunderdrums are larger than normal adults ones. They have three main colors on their body: Blue, Turquoise and Purple. Their wings have these three colors and many white specks. They have developed a larger talon on the edge of their wings. Their body is mainly blue in color. 

These Titans possess lots of sharp teeth and a long ledge, with its nostrils, on the top of its snout. Their second set of wings is larger and they have a row of spines along their tail and spikes all over their back. The name comes from its main mode of attack/defense. The Thunderdrum produces a strong concussive sound that can kill a human at close range. It is not only capable of temporally stunning other dragons but also can even extinguish flames shot by other dragons. Only the Screaming Death has a tolerance with this attack (able to stun it temporally). 

By combining the roars of several individuals, the roars are able to knock away several large dragons at mid-distance and instantly and literally blow them off. Like its sound wave booms, a Thunderdrum can shoot blue blasts of fire that get bigger the farther they go. And these fire blasts also travel at the speed of sound. The downside to this power is that it takes a lot out of a Thunderdrum to employ it, so it's not often used. Thunderdrums can blast waves of blue fire if necessary, but this uses a lot of energy. Training a Thunderdrum, especially as an adult is a challenge as Thunderdrums are almost deaf. 

Showing protection and gaining the Thunderdrum's trust is an easier way to train it. Adolescents also don't or can't listen except to mature adults. It is easier to train one from birth or have an adult to help. However, adults can be very protective of their young, regardless of their offspring's' ill-behavior. Understandably, they are strident and assertive, the loud Thunderdrum always makes its feelings known. Adolescents are shown to be mischievous to people and dragons alike as they can be very annoying to them. However, the adolescents will acquiesce to any adult of the same species, regardless of relationship or lack thereof. Thunderdrums are so stubborn that they can be tough to train. Thunderdrums show a real parental instinct to any young, even if it's not their own. Thunderdrums also have a habit of holding grudges against their enemies.
