Hyanos/Demonic halfbreeds.
Born of a human parent and an Aratama Yokai parent, Hyanos take traits from both their human and yokai parents. It is important to note that certain characters in the base series will be made into hyanos to justify their bizarre appearances and strange starting abilities (Such as orochimaru). Often times Hyanos will resemble a mix of their yokai parent’s traits and their human parent, however on a genetic level, due to the chaos of the yokai parent, often times chakra natures in particular are scrambled and can arrange themselves in strange fashions, causing sudden developments of Elemental kekkei genkais in particular, though not super common. Hyanos will often also develop physically unique traits, such as enhanced smell or other senses as a result of their yokai parent. Due to the fact that Yokai always possess nature energy, as it either physically helps make their bodies or is what made them in the first place, all Hyanos have an inherent supply of nature chakra inside them. This energy however is closer to the chaotic nature of something like Orochimaru’s curse mark, though without the mental degradation. this supply naturally will recharge itself from either the world around a hyano or the hyano’s own natural chakra converting into this nature chakra, as this nature chakra is considered by their body to be higher on the priority, which is also why their bodies are abnormal in appearance. As a result, a hyano can almost always infuse attacks with nature energy, massive improving their power, though they cannot use too much of it or else their other yokai traits may weaken, weather that is physical strength being enhanced or their senses dulling. Hyanos, unlike their parents, are also capable of mastering sage mode, which is mostly used to balance the already present nature energy in their body and grant perfect control over it and of course grant the sixth sense sensory abilities sage mode is known for, but this of course requires the same effort and training as normal humans. Lastly as a last ditch effort, a Hyano with above average chakra control can feed their chakra into their nature supply to go into what is refered to as a Yokai shift, in which they normally resemble a smaller version of their yokai parent or sometimes even their own appearance based on who they are, this natrually enhances all their abilities at the cost of self control in most cases if used for too long and even potential death if all normal chakra is converted. One final thing, any jutsu, elemental kekkei or not, that is made by a hyano intentionally infused with their nature energy cannot be replicated instantly by a sharringan unless the user of the sharringan in question has access to sage mode or some other method of using nature chakra.
