Four Guardian Beasts of Hell's Gates

The Four Guardian Beasts of Hell's Gates are large behemoths that are the major plotline drivers in the fanfictions, Naruto: Kimza Chronicles and Kimza Chronicles: The Last Sealer. They are differentiated by their appearance and the color of their chakra. They are living masses of chakra that rival the power of the nine Tailed Beasts, giving them power that surpasses most shinobi. Despite being part of one class, the Guardian Beasts were always seperate, so they have seperate chakra colors.

Like the tailed beasts, the Guardian Beasts possess human intelligence and sometimes intelligence surpassing that. This gives them the ability to utilize their chakra for jutsu as well as use their elemental natures properly. However, unlike the tailed beasts, the Guardian Beasts appeared at random and were without any knowledge on them. Currently, they are classified as documents to be researched but are also wanted for their power. In Ezemaru Kimza's case, Guardian Beasts can be sealed within humans to utilize their power and abilities.

The Guardian Beasts also have a link with one another and can communicate via telekinesis. They can also communicate with the one they're sealed inside. However, the lack of saturated chakra in the shinobi world limits their ability to speak to each other properly. Guardian Beasts can leave residual chakra behind as a beacon for its fellow beasts. They also have the ability to turn into pure chakra whenever their body is destroyed and allow themselves to regenerate. They can also become whatever their dominant element is and become a nature.

History
The Guardian Beasts were formed in Tenga Hell, a world within a giant interdimensional rift, during an specified time by the ruler of Tenga Hell, Saichu. They were formed from four of five hearts Saichu had. Bukarok was the eldest, then came Asura, Issaru, and Roku was the youngest. Due to this bond to Saichu, these four creatures were the most powerful beings in Tenga Hell behind Saichu. They were tasked with Guarding the "Gate of Tenga Hell", a weak point at the edge of Tenga Hell, and keeping outsiders from reaching the world abundant with powerful yet dark chakra. Asura and the three creatures were known as the Four Guardian Beast of Hell's Gates. Bukarok was placed in the north of the gate, Asura in the south, Issaru in the east, and Roku in the west. Saichu told them that they were siblings that would help and protect each other. He also told them that they would combine to become one powerful entity to one day seal the gate and keep the peace forever, but only after they reached their true power. The four combined their power to keep the gate strong and nearly impossible to open. Despite being thousands of miles from one another, Asura was able to communicate with its siblings using telepathy.

Many thousands of years passed and the gate remained untouched. However, about 100 to 90 years before the start of Naruto, the gate was foribly open and dead humans were thrown into Tenga Hell by an unknown force. The Guardian Beasts were shocked that humans, who were constantly watched, were able to force open the gate to Tenga Hell. It was the Kuguari clan that opened the gate, using their clan jutsu, the Kuguari Style: Banishing Vortex Technique, for the first time. For the next fifteen years, humans were thrown into Tenga Hell through the gate at a regular basis. The Guardian Beasts relayed messages to Saichu, who instructed them to find a way to end it. However, it stopped for a few years, only to start again. At the end, a few dead Kuguari clan members were known into Tenga Hell after the climax of the Kuguari Village Civil War. The Guardian Beasts inferred that these clan members were the cause and they were probably thrown in, never to open the gate again. The clan was therefore known as the Sealers.

After a few years, a series of tragedies struck. First, Asura, Issaru, and Roku lost touch with Bukarok, who vanished without a trace. Then, the gate suddenly disstablized that threatened to open, possibly to merge the two worlds or even destroy them. Even though the three remaining beasts manage to avert it, they knew it was only a matter of time until the gate was opened again due to his imbalance. Risking themselves to save Tenga Hell, Asura, Issaru, and Roku let themselves out into the shinobi world and awaited Bukarok to call them. Bukarok was sealed into a scroll, then Ezemaru Kimza, Asura became a stone mountain, Issaru became a series of whirlpools west of the world, and Roku vanished altogether. They secretly swore to join up one day, and destroy the Sealers to prevent Tenga Hell from being threatened.
