Shodaime Character biography :The first of all hokages, he was the founder of the Hidden Leaf Village, it is unknown the orgin of his lineage. The first hokage had an unique exquisite type of chakra element, which is the Hidden Wood element, and with that ability he was able to bend to his will the giant demons known, as Tailed Beasts (Bijuu's) to his will and suppress their chakra, and his darkness jutsu and suiton might be very good counter-moves to Madara's Sharingan and katon respectively as well.)
Madara Uchiha
Deceased (Or not !?)
Son (most likely) of Sojobo (Tengu Demon)
Orignal Uchiha - Founder of the Uchiha Clan
Madara Character biography : Madara soon became a hero in his people's eyes despite his young age. And Madara founded the first police force in the Konoha and swore to protect his people with his life. He was the first normal Sharingan user and the first MS (Mangekyou Sharingan) user that could cast 3 types eye techniques jutsus–Tsukiyomi, Amaterasu and Susanoo. These are the abilities of these different Sharingan techniques:
1. Tsukiyomi- the ability to control people's minds and drive them insane.
2. Amaterasu- is to teleport objects or the user into another dimension.
3. Susanoo – is the ability to create a storm like that created by a Tengu's fan.
And he had his normal Sharingan on 24/7 just like his Hyuuga kin, And he would just turn on the Mangekyou Sharingan when it was needed. And with the Kyuubi power and chakra fused into Madara he was able to mastered the katon and he could even cast a dark fire that would burn for 7 days and 7 nights after performing the Amaterasu. He could also communicate with people telepathically or even invade their minds and drive them to madness.
The Konoha Tengu Story
There are two types of tengus, Karasu tengu (a crow-like creature with beak and wings) and Konoha tengu (also known as Yamabushi tengu). Sojobo was a Konoha tengu. He had long nose and white hair with a pair of black wings on his back. As the King of Tengu, Sojobo possessed some very mystical powers. He carried a fan made of Fatsia leaf that could create a storm (therefore people sometimes call this type of leaf as Tengu no Uchiwa or Tengu's fan). He could teleport himself or any other things from one place to another. He could also communicate with people telepathically or even invade their minds and drive them to madness. Besides, Sojobo was also known for his shapeshifting ability. He sometimes transformed himself into human to interact with people.
Anyway, this girl from Hyuuga was in love with Sojobo taking the human form without knowing his true identity. She married him shortly after they met each other. A year or two later, she was pregnant and gave birth to their first son. Sojobo named this son Uchiha, Uchiha Madara, after Uchiwa which means fan. And of course as we know, fan also later became the symbol of this new clan. As Madara was about to reach his adulthood, Sojobo began to reveal his true intention. Sojobo didn't marry the girl from Hyuuga out of love. He was only looking for a perfect body, a container (probably to achieve greater powers), and he figured the best way was to create one with his own blood. He was planning on taking over Madara's body once he reached his adulthood.And it didn't take Uchiha Madara long to find out this appalling truth. He felt a mixture of shock and anger. He felt he was being used but he wasn't going to give in such easily, at least not without a fight. But Madara knew only too well that no matter how strong he was he stood no chance against the King of Tengu. Out of desperation he sought for the legendary Bijuu—Kyuubi (the God of Fire). And Kyuubi was very impressed by Madara's abilities. A secret pact was made But even with these newly gained powers and a huge supply of chakra from the Kyuubi, Uchiha Madara was only able to beat his demon father by a hair's breadth. He couldn't finish him once and for all but only managed to seal him up. However, the seal he used was a very special one. To break the seal it requires the Kyuubi's chakra and also not one but 3 Uchiha members wAho can wield the Mangekyou Sharingan. –combine, the great evil will be unleashed. It's a tall order and Madara thought it would be enough to seal up the demon for eternity.
Hold on everyone here's where it gets very interesting when you learn about the Karasu-Tengu demon.

The friendship
Madara became very close friends with Shodaime and together they took up the responsibility to protect the Konoha village they established. And about the relationship between Shodaime and Madara. When Shodaime found out about the secret pact between Madara and Kyuubi he was enraged. He thought it was hunger for greater power that led his best friend to the Kyuubi. Madara didn't explain to him either because he didn't want anyone to know he was a half-demon. Conflicts began to appear between the two who were once close to each other. The intense hostility eventually resulted in a great battle at the Valley of the End.
