The Nemesis of Man (Kidomaru stuffs | Mostly Canon)

Name: N/A - No clan. It is unique to the Lying Swan, Hakucho.
Appearance: Wielders of this kekkei genkai have a spiralling birthmark that will circle around various parts of their body, growing as they grow in age.
KKG/Ability:

This kekkei genkai transforms its holder into an apex predator. Highly intelligent and with excellent analytical abilities, he can sense hesitation, read lies through physical expressions (of course, this isn’t infallible; a kekkei genkai or specialized technique could allow one to avoid detection), and otherwise make up for the fact that its holder doesn’t have much experience with the people of the realm he’s landed himself in. A third eye rests unopened on their forehead, usually covered by hair or a headband. It grants chakra vision, increases the level at which things that are outside of human visual range but still within the horizon can be processed (40% increase), and allows greatly increased accuracy. The accuracy increase is great enough that it can be used to target the Byakugan’s weak point without problem, should one discover it.

Possessing six arms, their additional hands can be used for virtually all things. They are fully functional, in every way. Additionally, they scale with puppetry in much the same way as well. They can have 3 times as many puppets as a standard puppeteer of their rank could have - allowing an A-rank to wield 30. At S-rank, they can wield 40, at SS-rank 60, and at X-rank 60. Likewise, they are ambidextrous and can use all the skills they learn instantaneously with every hand.

There are spinnerets in the mouth, and the user can produce silk and golden silk from their pores as well, though the spinnerets allow the user to produce silk and golden silk from their sweat pores as well. Obviously, these require techniques to manipulate.

Notably, as he is soulless he is incapable of procreating.

There were changes made to the user that let will let them harness certain things, including the additional brainpower that this kekkei genkai provides Not really a super genius ability or anything, this change has to do exclusively with their ability to process information and the performance of their brain in accurately doing so, thus not increasing their intelligence, but rather giving their access to the brain functions to use these eyes (note: this lets them use the orbs of sight, essentially, without their brain glitching out from all the information; I guess this could also apply to registering things moving at high speeds, as well, but wouldn’t provide a speed boost).

The venom sac that users have has lets them use poison and venom based ninjutsu outside of medical techniques and to bite individuals with his fangs (which can penetrate steel, but it is next to impossible to get the chance to bite a ninja), but targeting it will likely remove it from use for several months, with the potential for killing people below S-rank outright (50/50 chance); Hakucho’s venom sac personally usually contains a paralytic venom that lasts for about five minutes per bite, and has the attributes of the most dangerous Lactrodectus (black widow) poisons when Hakucho wishes to do more than paralyze someone, but it can also become powerful enough to drop a horse with a single bite even through the Jutsu that allows Hakucho to change the venom.

They are capable of using much more sophisticated mimicry techniques than other kekkei genkai or hiden users are able to. Their techniques mimic the natural abilities of a spider, and make use of them. This could include a jutsu to create spines like other spiders have that allows a spider to hold onto surfaces, using them for wrestling or to impale people, and even using them with their armor on, or it could be a Jutsu where the user mimics the jumping spider’s jump with chakra, enhancing a bite or extending their fangs in a way that allows them to penetrate substances like certain spiders can, or even allowing themselves to see in infrared just as spiders can. Their advanced capabilities also allow him to masterfully use his spider webbing, allowing them to do things like wrap opponents in it once he has a hold of them, create intricate traps, and use golden webbing to create just about anything needed (like a key).

One of these Jutsu that one might come to learn is called the Orbs of the Spiderling, and it is a Jutsu that, stays active once learned with a very low chakra constant drain on the user unless deactivated (this resulting in a deduction of points). The technique creates six blank orbs that the user is able to see through the surfaces of, bringing the total number of eyes that they have up to nine just as a properly freakish spider should have. The milky, white orbs that they have are just made to provide sight, but they can use certain Jutsu that allow the mimicry of spider attributes through them, as well as use unique Jutsu, but not to produce spider silk through them. Again, the only truly innate ability of these eyes is to see things.

Warning: This kekkei genkai cannot be acquired through implantation as it is incompatible with human biology. Only two human clans are capable of surviving meshing with the flesh and blood of its wielder: those that wield the power of the ash bone, and the self-resurrecting, easily regenerating shinobi of a certain clan. Of course, that doesn’t mean an enterprising medical ninja will never develop the idea to plop extra arms on a shinobi, as the Satsujin-han have with one of the clans that serve them in the Conspiracy.

Clan Jutsu: (This can be filled out later if you wish, because jutsu are made individually and linked separately)
