The Uchiha are descended from the Hagoromo, a clan of corvine demons arising from the birds who consumed the flesh of Hagoromo Ōtsutsuki, the first God of Shinobi. They share this history with the Hyūga, from whom they split due to ideological differences.
At some point in their pre-Oinari history, the Uchiha, who had settled long ago in the Land of Birds, would fall victim to a terrible degenerative disease of the mind and body, causing the survivors starting with Madara Uchiha and his generation to give up their former practice.
Eventually, they encountered the Anokudatsu, a skulk of kitsune who could turn dead matter into precious stones. Thus, the Uchiha of today wean themselves from necrophagy by gathering dead matterdead animals, dead Mt. Oinari civilians, dead enemies or missing-nininto corpse scrolls and giving them to the Anokudatsu to work their magic.
A majority of the Uchiha are black-haired and eyed in their human forms, something that remains consistent in their Demon and Berserker forms. Being ravens, their Demon forms maintain the scruffy all-black plumage, complete with throat feathers.
Like most shinobi, the Uchiha are fluent in Japanese and English. But when they use the Sharingan, they can instantly learn, understand, and speak other languages from reading a foreigner's lips or handwriting, even something as foreign as Arabic or obscure as Latin. Also, they communicate with each other with sounds they mimic from their surroundingsclicks, beeps, rattling, chiming, etc.
Unlike most clans, there is no rhyme or reason to the names of Uchiha members. They're not named after body parts (like the Inuzuka), anything pertaining to the sun (like the Hyūga firstborn), gemstones (like the Anokudatsu), nor do their names have a set prefix (like the Aburame, Yamanaka, Nara, or Akimichi firstborn). This is because the Uchiha aren't born with a name; they choose it themselves.
When an Uchiha is born, they are given the name Kogarasu ("Child Raven") until they're old enough to fly, speak, and feed themselves. On the birthday after they've proven themselves old enough, they're sent out to find their name. For reasons cited above, the aforementioned naming themes are forbidden, as is naming oneself after a deity or anything pertaining to their species. Often, these names are nouns, concrete or abstracti.e. Itachi naming himself after the first animal he saw, or Mikoto naming herself after a title associated with deitiesand always in Japanese.
For the most part, the Uchiha are even-tempered, with a sense of humor that can range from dry to just plain cutting or dark, with a side of mischief. They're also very intelligent which, like the animal they're based on, allows them to find ways to survive any climate no matter how harsh, and to think of solutions to problems in high-stress situations.
Also like ravens, Uchiha tend to cache their food/possessions and steal the same from other Uchiha. This is actually considered necessary, if not annoying, as they consider it good practice for when they become shinobii.e. retrieving enemy documents without knowing how heavily guarded or booby-trapped it is.
Another thing Uchiha love to do, like their species of demon, is to go flying, especially if they can perform feats such as flying in loops. In fact, much like caching and stealing, such feats are encouraged, as it prepares them for dodging attacks while in flight.
Like the corvids they're based on, Uchiha will eat anything that's edible. Nuts, fruits, vegetables, eggs, bugs, meat, carrion. This diet once included human corpses, but due to the Illness, the Uchiha of Madara's generation and onwards would give up their necrophagy.
Rites of Passage
After choosing their own name, the next Uchiha rite of passage is the ability to use their most basic technique, the Grand Fireball. As soon as that is mastered, the Uchiha in question will be allowed to wear the clan's namesake symbol on their clothes. Also, they will immediately go to the main temple of the Anavatapta Shrine and go to the secret meeting place under the seventh tatami mat from the right. Once there, the Uchiha in question will read and memorize everything etched in the tablet about the clan's history.
Like their canon counterparts, the Uchiha of Mt. Oinari also have the Sharingan that allows them to copy non-Bloodline jutsu and can advance into Mangekyō. But unlike its canon counterpart, this version of the Sharingan comes at a price for its natural bearers: eisoptrophobia, the fear of their own reflections. This phobia is not without justification either, for if Uchiha are to look upon their uninterrupted reflection the following will occur based on their Sharingan level:
Dormant: 72 hours of unconsciousness
Awakened: 72 hours of migraines
Mangekyō: 72 hours of migraines and seizures
There is, however, an exception to this: if the Sharingan user is not a born Uchiha, they're immune to this phobia.
Also, this Sharingan cannot be taken by force; it has to be given by the natural bearer. Otherwise, once the stolen Sharingan is implanted, it will implode the thief's brain or gangrene the body part in which it is implanted.
The Mangekyō Sharingan also has its costs. Once activated and depending on jutsu usage, the user will be blind in that particular eye for 72 hours.
The Mangekyō Sharingan can only be achieved by going into and reverting from the Karasu Tengu berserker state for the first time. This state is induced by consuming pills made from the panther cap mushroom and as the name implies, takes the form of a tengu with corvine characteristics. And much like the ancient depiction of tengu, this berserker state renders the Uchiha in question little more than a bloodthirsty killing machine, their intelligence supplanted by bloodlust and unable to distinguish enemy from ally. For this reason, they only induce this state as a last resort and warn their allies to clear their line of vision. The Uchiha in question will revert back to their normal state once their bloodlust has been sated or if they see their reflection. Once reverted, the Uchiha will be rendered feeble and unable to use chakra for 72 hours.
And to further prove my nerdhood:
*After everything I learned about ravens (mostly from here and here), as well as YouTube, I figured, "why not portray the Uchiha as raven demons?" There's gotta be more species of demons than Naruto and his ilk, and besides--don't they look pretty corvine to begin with?
And before you ask, no, my version of the Uchiha don't lay eggs. In my 'verse, once demons attain human forms, they become viviparous like humans.
*As far as the tengu connection, the Japanese tengu were originally avian creatures and are sometimes portrayed as guardians of mountains, as can be read here. Also, note the mention of karasu tengu.
*As for the berserker part of it and the mention of panther cap mushrooms, that started out as most of my Naruto ideas do: linguistic curiosity. I looked up Japanese words and phrases containing the characters for "tengu", and one that stood out was tengutake, the Japanese word for the panther cap that can be reconstructed as "tengu mushroom". And then I remembered reading that psychedelic mushrooms were among the theorized causes of the original berserker state in ancient Vikings. Thus, berserker Tengu mushrooms.
*Anavatapta Shrine as opposed to Naka. In yet another bout of linguistic curiosity, I learned about a mythical lake called Anavatapta, which is described as being surrounded by riches. So I figured that'd be more fitting for the Land of Jade than Naka.
*And the disease that causes them to give up necrophagy? Creutzfeldt-Jakob disease, a degenerative brain disease caused by eating contaminated human flesh.

The Uchiha are not my favorites, but I like the idea.
Hyuga and their firebird state reminds me of naruto's bijuu cloak mode.
Oh, I'm sure it would...
I'm surprised you haven't said anything about the Hyuuga having the other half of the Rinnegan instead of the Senju...
I read through and i couldn't find the rinnegan part maybe i'm just tierd. ;v;
Having the rinnegan and byakugan linked would be cool,The marks of the rinnegan could be added to the byakugan when it turns into the rinnegan smart idea.
Hey, they wouldn't be Uchiha if they weren't crazy or eccentric in some way...
Personally, I think Tim Burton would have a field day with these guys
Tekka uchiha dosen't get a speaking part anyway in anything poor guy but
i always liked him.
This was fascinating to read! I can tell there's a lot of mythological content here and yet I still learned something new! I never knew that detail about that particular mushroom!
And well done for mixing corvid behavior and shinobi practice into an interesting culture! I can't wait to see how use all this!
Yes, all good characters need some flaw. I remembered thinking, "Why doesn't anyone just use mirrors to reflect the Sharingan?" Then I figured it must be due to logistics; what shinobi in their right mind would carry a mirror into battle? So I decided to make reflections the weakness of my Uchiha.
And yes, it's amazing what you can learn in bouts of linguistic curiosity, especially from this site. I am thinking of changing the mushroom from the panther cap to the death cap. Like the panther cap, the death cap's kanji also contains "tengu". In fact, its kanji can be reconstructed as "Tengu in the Making Mushroom". Of course, as its name implies, the death cap is a deadly poisonous mushroom. So what if I made it deadly...to everyone but the Uchiha?
