During the creation of the great nations, a small family revealed their selves to the world. This family was known as the Tepes family. The Tepes family claimed to be hundreds of years old and demanded to create their own great nation as well. The other nations laughed at this and ignored the matter. They saw them as too small to worry about.

The family at the time held about 150 people. After being mocked by the great nations, the Tepes took matters into their own hand declared war against the five great nations. The villages decided to leave the matter into Kumogakure's hands.

"They're small, there's no reason all of us should have to fight them." The villages all claimed. The first Raikage offered that he and his shinobi will deal this Tepes family.

Three days later, the Tepes invaded Kumogakure. The raikages confidence would be the death of his men. The Tepes burnt the newly formed Kumogakure to the ground. Leaving few survivors, the Raikage being one of them. The Tepes lost one man during the invasion.

The raikage would flee his small village with a few shinobi, now that the Tepes made it their home. He would go to Konoha and tell the Hokage how they're more than they thought they were and that help was needed to deal with them and to take back Kumogakure. The Hokage would alert the Tsuchikage as well. Thus leading to an temporary alliance between Konoha, Kumo, and Iwa to take down the Tepes.
A total of 1000 men, each from the three different nations would knock at the entrance of the Tepes reined Kumogakure during the night. A war would start between the 1000 shinobi and 150 Tepes. The shinobi eventually figured out that some thing was not right about this ninja. They were not human. They could not be killed by blades and bombs.

The three nations then decided that sealing the Tepes would be the best bet on victory since they were difficult to kill. It was then that the odds started to play in the nations hands, as they began to seal away large amounts of Tepes family. Throughout the night, this war would continue. Men were sacrificed to just to seal the Tepes members. Slowly the Tepes numbers dwindled lower and lower. This resulted in the current heir of the Tepes family retreating, along with about 45 other members. They made it a point to retreat right before the sun had rose.
This victory belonged to the nations and Kumogakure was rehoused to the Raikage and his surviving people.

The Tepes went into hiding. All though they were searched for by elite trackers, they just could not be found anywhere. They were slowly forgotten and not spoken of. Until they Reappeared many years later.

Through out time and many generations, unusual vanishings from shinobi in all the great nations except for Suna would pop up. These vanishings usually led to war with other nations thinking it was each other to blame.
Until some of the missing shinobi began to return home. All with one unusual trait, pale skin and red or silver eyes. Some of the missing shinobi that returned were missing for many years but seemed un-aged. This continued for awhile. Some missing shinobi came back, some were never seen again.

Until, about 30 years ago. The Tepes family revealed their selves again. With the same leader as before, showing that they really were 100's of years old. The amount of members this time was around 400. Shortly after revealing their selves again though, the leader of the clan was slayed by one of his members.
The culprit was never clearly named, all though it was assumed he was the next in line for the thrown of the clan and grew tired of wait or just didn't agree with how the leader was running things. Shortly after his death, the clan faded away again and actually dispersed. Hiding it the great nations and portraying their selves as shinobi of the villages.

Till this day, it is supposed that the one who killed the leader is currently in the throne of the Tepes clan and that all the members are scattered through out the world in the different villages. All though, even they dispersed they are working together still.

There is a hierarchy in the Tepes family since the new leader took his/her throne. All though her/his identity remains a mystery to the world.
Since the rise of the new leader there is an overall heir of the clan and then four clan sub leaders that rule their own nation. Beneath them is just overall members who are all equal. The 'tainted bloods' are treated the poorest out of all though. All this was established under the new heir of the throne. (Explained in more detail in the members spot)

Fang&Claws: The Tepes bodies work as weapon. They are equipped with powerful 'vampire' canine teeth and razor sharp nails. Both powerful enough to cut/rip through flesh.
These claws and fangs grow stronger as one ranks up.

Genin&Chuunin: Works like cat claws, can use them to scratch enemies but you're not going to kill some one with them.
*1/3-3/4 inches deep

Special Jounin&Jounin: You've mastered how to use these claws and fangs in battle, of course your fangs are manly just used for turning. All though your claws are quite destructive now and may be used to cut through wood or severely injure some one. Death can be done with these, all though it's still difficult. Aim for their neck at this state, trying to aim for their chest or such won't be any good considering their bones protect them.
*1/3-6 inches deep.

Sannin&Kage: Go wild. You've learned how to use your claws and fangs to their full power and are dangerous weapons on you. With the correct jab you could rip through a person's body or with the correct slash cut fingers off. Your enemies won't want to get into too close of combat with you.
*1/3 inches-9 inches (Capable of severing body parts.)

Turning: Turning is a natural born gift to pure bloods. This allows a Tepes to turn another person into a Tepes/Vampire. All though, when some one is turned by a pure blood they are known as 'tainted' blood and are often times looked down by a majority of Tepes. All though some of the Tepes still accept them. Turning for PC's has to be accepted by the person being turned. As for NPC they can be turned regardless of if they want too. Turning is done by biting the target, they will feel a great amount of pain for two post, after these two post the transformation is done and the target is a Tepes vampire.

The rules that apply to the pure bloods apply to the turned Tepes as well afterwards. After turned though, any past blood lines are over written. Meaning that if a Uchiha is turned, they are no long a Uchiha. They are a Tepes now.

*Turned/Tainted bloods can't turn others. Only pure bloods. To be a pure blood you must start with the Tepes clan.

Sunlight: The Tepes are vampires, they are extremely weak in the sun light. This causes them to stay indoors a lot during the day or reside in caves and such. The following are affected when in the sun.
-1 speed
-1 strength

Cursed Senju: The Tepes are extremely vulnerable to the Senju's wood style.
+2 ranks in damage from wood style (Mokuton) techniques.

Inhuman: Members of this clans have tough time accepting medical ninjutsu. Thus meaning that it is difficult for their wounds to heal.

*Members must take Pharmacophobia as a clan Negative Special Characteristic and can't have a positive to balance to it.

Range: Close Combat
Specialty: Taijutsu
Duration: N/A
Cooldown: N/A
Description: The Tepes punches at the enemy with constant and quick attacks, the user hides the real attack in these punches though. After striking at the enemy with some time with just punches, the Tepes will form one of the hands flat and hide a jab in their barrage of punches, due to their razor sharp claws this jabs becomes a stab and if used in the correct spot can become quite fatal.
Due to the speed of the punches, it's hard for the enemy to recognize that one hand changed shaped to stab the enemy. Making this a shady but clever attack. *Refer to the 'Fangs&Claws' section to see how powerful your claws are, that will determine how powerful your strikes are with this technique.
