A humongous beast with bull horns and a massive club tail is seen taking his time devouring large chunks of wood in the forest floor in the Deserted Island, peacefully eating away as herd of Aptonoth and Gargwa munched on grasses not far away. This creature is the Tail Hammer Wyvern, Duramboros.

Duramboros is just minding his own business when a huge bellow echoed throughout the forest, causing the Aptonoths and Gargwas to panic and flee in fear. Annoyed, he turns to the source of the noise just as a huge golden creature bursts out of the trees and bellows. This is Uragaan, the Burst Hammer Wyvern.

He had been evicted out of his home in the Volcano by an Brute and was forced to seek refuge from the Deserted Island. He'd just so happened to stumble into Duramboros' territory.

Seeing Duramboros as competitor for territory, Uragaan pounds his chin four times and roars to intimidate him, but he is not fazed. In response, Duramboros smashes his club tail twice and roars, to show he is not giving up his territory. He makes the first attack by charging with his horns, to which the Uragaan parries with his chin.

The two titanic Brute Wyverns began pushing each other horn-to-chin as they struggle to overpower their adversary. In the end, Uragaan successfully pushes Duramboros back before flinging several magmatic rocks near him. As Duramboros looks at them in confusion, Uragaan raises his head up high and slams his chin the the ground, the vibrations o the shockwave caused the rocks to explode, catching his opponent by complete surprise as he roars in pain.

As Duramboros falls to the ground, Uragaan rolls into a ball and began circling around his opponent, waiting for the right time to strike. Duramboros manages to get back up, only to get knocked down again by the rolling Uragaan and repeated the same move over and over again. Enraged, he got back up and begins spinning with his tail out, transforming into a spinning hammer.

Uragaan is surprised by the action but continues to circle his spinning opponent. It was a rolling hammer vs a spinning hammer. Eventually, Uragaan decided to break the stalemate by charging at Duramboros, big mistake. As Uragaan closes in, Duramboros' hammer tail swings at the right timing and strikes Uragaan in the face, breaking Uragaan's chin at the cost of denting the case of his hammer tail.

Uragaan roars in pain and tumbles as he writhes in agony, as Duramboros roars in pain from having to lose the case from his main weapon. Both Brute Wyverns recovered and roars in anger from losing primary offense. Duramboros charges with his horns and tackles Duramboros to the side knocking him down and began skidding him against the forest floor, knocking down several in the process. Uragaan kicks Duramboroso in the face to stagger him as he got back to his feet.

He flings several rocks at Duramboros, but he spins and knocks them back near Uragaan's feet and slams his hammer tail down, using Uragaan's own attack against him as he got staggered from pain. Duramboros uses this to attack and lift Uragaan with his horn before tossing him over his shoulder. Uragaan slams into the floor and laid there with a groan, unable to continue the fight.

Sensing his opponent is no going back up, Duramboros raises his tail one last before swinging it down unto the Uragaan's face, causing a loud boom followed by a skull cracking as Uragaan got his head caved in from the Duramboros' tail. He twitched for a moment before going still.

Duramboros, knowing that he had killed his rival, raises his head and bellows in victory. He then walks away from Uragaan's body and begins to munch of some fallen trees, exhausted in his fight.

Winner: Duramboros
