Batoru Or Harken Stampede is a Battle Wolf. Second youngest of the make shift brothers. Due to the number of irregularities in Batoru it is unknown if he is the king of the species or not.

The Battle Wolf is the largest and most powerful wolf species in the world; a presumed extinct species but one of its survivors has been revealed to be a member of the fearsome Eight Beast Kings. Its presence is enough to make even some of the world's most dangerous beasts shake in fear, earning it the sobriquet "Legendary King".

The Battle Wolf is a large wolf beast with brilliant white fur, two blue marking beneath its eyes (which are black with pink pupils) and a proud mane that gives it a regal appearance befitting its title of "Legendary King". A Battle Wolf at birth is no bigger than a regular adult wolf, however within a short amount of time it can reach a great size and even grow as big as ten feet in height while still only being a pup. After this it will go through numerous growth spurts at a great pace eventually growing 8 meters (26 feet ) in height. It is also shown that an ancient Battle Wolf was easily 50 meters (164 feet) in height, showing that they can reach titanic sizes. Batoru has a odd genetic mutation that lets him freely go from his 50 meter to his 8 meter size. Batoru specifically seems to have paws that can work similarly to hands including a thumb like toe.

Battle Wolves are perhaps the fastest creature in the world; even a newborn can run 100 meters in 1.5 seconds. It is an intimidating omnivorous animal with incredibly sharp claws and a gargantuan appetite, which terrifies other beasts. An adult Battle Wolf, even while weakened, can tear other beasts to shreds virtually instantly. The Battle Wolf possesses incredible inborn instincts that show themselves the moment they are born. They also possess immense strength, being able to cut clean through rock and steal in a single bite. They have an incredible growth rate, as a Battle Wolf pup is capable of growing to an enormous size in less than a year. They are also noted to have high intelligence, and have the innate ability to detect danger and warn its allies before harm can befall any of them. As well as having a few telepathic abilities allowing them to communicate telepathically as well as being able to hypnotize other creatures to be more willing.

Besides possessing immense strength, what truly set them apart from most other beasts is their sensitivity which allows them to sense potential dangers, and has helped them survive mass extinctions and even sense the emotions and true intentions of others. Most of the time these creatures are solitary and distrusting but it is possible tho extremely difficult to have one as a companion. A battle wolf blood is often considered cursed due to the fact that most creatures that draw blood have their claws and teeth  dissolved to the bone in a instant, and the wound on the battle wolf would heal rapidly. If he stabbed his hand into a creatures body part it would start to spray a mist of blood as the area bubbled and melted away. Often causing a entire body to disintegrate to bone if stabbed close to the heart to make the effect spreed everywhere. He has been seen making this effect happen to the environment tho rarely.

 

Most battle wolf only have one form. But due to prolonged exposure to demonic  energies he can take on a more demonic form. Mostly because he constantly takes Sakagami's Gilgimesh.

As for breeding because of its large size it has adapted the ability to change its cocks size by changing the density (meaning that it will be much harder then normal. Batoru however can only get his down to a 3 foot length with 3-4 inch thickness and a 6-8 inch knot. Its sack only able to go down to large beach ball sizes at minimum. And due to the rarity of the creature even when they were plentiful can have 2 to 4 cocks for multiple partner breeding with up to 2 sets of sacks to fuel them. As well as having potent enough semen that the Battle Wolf species can impregnate virtually any other species as Its genes will be more dominate. The children will even be able to reproduce as well.
 

Batoru seems to have a high effenity for the thunder element aswell as some ice.

 

His brother Zhi has even tought him the ways of the soulweaver/smith and shadow hunter to put his speed to greater use. Batoru even having his "spiritloom/forge" on his arms partway at all times. Letting him put out the unnatural thread with ease for use.

 

He has several decks. . One for games and the other for...explosions.
