I am providing two options for Dojutsus...feel free to use them, mix and match or create your own. All I ask is NO Sharingan or Rinnegan.
OPTION 1: OP ROUTE:
Kuromegan(Black iris/eye wheel)
Stage 1: Both eyes becomes pitch black
a. Shadow Sight(Kage no kokei): When the dojutsu is activated, it gives the user enhanced vision.
1. Telescopic vision: Allows user to see great distances(with proper training a person can see up to 8km)
2. Infrared perception:The user is able to perceive the infrared spectrum(i.e. temperature), allowing them to see temperature variations in objects, people and the environment. Allows practitioner to see the heat presence of any living target.
3. X-ray vision: Allows user to see through solid objects.
b. Shadow Weapons(Kage no buki): gives a person the ability to manipulate shadows to create tangible weapons that disappear on impact(practitioner is able to produce any type of weapon, but the larger the weapon, or the longer it's in use, the bigger the drain on the user's chakra supply).
Stage 2: 1st purple tomoe appears to the left
a. Cloak of Shadows(Kage no manto): allows the practitioner to condense their own shadow around them and wrap themselves within it, hiding themselves from scent, sensors and dojutsu users( When staying within a shadow for prolonged time, it will result in quickly draining the person's chakra. Despite the fact that the practitioner is invisible to the world, his physical body is still present. So if an attack was to strike him/her, the person would still be hit)
b. Absolute Darkness(Ankoku no sekai): Allows the practitioner to release a field of darkness from their mouth that is impenetrable by normal sight or any dojutsus, but is still vulnerable to sound and smell.
Stage 3: 2nd purple tomoe appears to the right
a. Shadow Step(Shadousuteppu): Practitioner is able to jump between shadows, as long as they are able to see them. Since the dojutsu allows a person to see incredible distances, the jumps can go up to 8km. While this mode of traveling is incredibly fast, in sheer speed it is still below the Harishin.
b. Bullets of Darkness(Yami no dangan): Much like Kimimaro's ten finger drilling bullets, the user is able to launch up to ten shadow formed bullets from their fingertips. Upon impact, said bullets will release a small concussive blast.
Stage 4: 3rd purple tomoe appears below the silver pupil
a. Shadow Twin(Kage no futago): Practitioner is able to split their shadow into a twin of themselves(the "clone" is an exact duplicate of the original, and has the same amount of chakra as the original when it's made. These clones can do everything the original can do, and like Shadow Clones, once they dispel their memories are uploaded to the original. Unlike Shadow Clones, however, these clones don't dispel after a few hits. They will continue to fight until their Chakra is used up, or they are "killed". Once the clone is killed or dispelled, another one can not be made for a few hrs.
b. Fires of Darkness(Kurayami no kasi): Allows the user to release black flames from their hands. The flames can be directed towards different targets, and can match the Amaterasu in their intensity. However, unlike the Amaterasu they don't burn for seven days.
Stage 5: A purple ring forms that connects the 3 tomoes.
a. Shadow Drain(Shadoudorein): by touching an opponent around their head, you can put them into a forced sleep and steal all of their knowledge. The opponent is completely unaware during the process, but they will awaken moments after the drain is complete. The drawback is two fold; 1. The more memories you upload, the more Chakra it takes. 2. The memories aren't permanent. If you keep the memories too long, it will lead to brain damage. You must write down the information(knowledge/Jutsu) and purge the uploaded memories.
b. Shadow Binds(Kage ga ketsugo): Allows a practitioner to turn the shadows around them into several sharp needles, which can be controlled separately. They can then attack several targets simultaneously and take away their opponent's ability to move by sewing them stuck with the shadow threads.
Stage 6: The 3 tomoes spin clockwise
a. Living Shadow(Ikite Iru Kage): The ultimate form of the Kuromegan, the practitioner is able to turn their body into a shadow and become intangible. Objects will pass right through them, but the user themselves will be able to make physical contact with their surroundings. Along with the intangibility, the user gains a three fold increase in speed and strength. Prolonged use of this technique leads to massive drain on the chakra reserves.
OPTION 2: Powerful Route(I made this the other day for NarutoNega, but I'm unsure if he/she will use it)
Tenomegan(Heavenly Eyes)
Stage 1: Eyes of Clarity(Similar to Byakuugan)
User is granted Telescopic vision(up to 8km), X-ray vision(ability to see through solid objects) and Infrared perception(ability to see heat signatures in any living thing).
Stage 2: Eyes of Insight(Similar to Sharingan)
The user is granted incredible clarity of perception, enabling them to read lips or mimic something like pencil movements. In combat, this allows them to see fast-moving objects and once fully developed offers some amount of predictive capabilities: they can anticipate an opponents next move based on the slightest muscle tension in their body and act accordingly to dodge or intercept.
Stage 3: Eyes of Foresight(Spiderman)
The user can sense nearing dangers and sense unwanted or hectic threats to their well being, acute danger, potential immediate danger, evade danger, and impending danger. The intuition usually regards themselves, but may include their surrounding(distant car wreck).
Stage 4: Eyes of Weakness(a shatterpoint superpower)
The user can sense the weakness of almost anything, including people and objects.
Stage 5: Eyes of Truth(Legillimency from Harry Potter, with slight empathic ability)
When the user stares into a target's eyes, not only can they read the person's surface thoughts, but they can also tell what the person is feeling.
Stage 6: Eyes of Justic(Penance stare superpower)
By locking eyes with a person, the user can induce fear, pain and with prolonged used insanity.
