Shadow's Custom Techniques

[骨の鎧] Hone no Yoroi | Bone Armor
By manipulating the bone growth inside his body Shadow can create 1/2 thick bone armor underneath his skin throughout the entirety of his whole body. Able to even withstand a sand burial without issue.

[逆骨の鎧] Gyaku Hone no Yoroi | Inverse Bone Armor
Using the same manipulation as the above jutsu, Shadow creates a 1 inch thick armor atop his skin. The downside of this technique is the immobility it causes making it only to be used when needed.

[骨の弓] Hone no Yumi | Bone Bow
Using the spinal cord and a ligament/tendon these two items form to create a bow. The user can then use any bone from within their body to use as ammo or any premade arrows.

[骨の矢印] Hone no Yajirushi | Bone Arrow
These arrows are made specifically for Hone no Yumi. Made from the bones in the arms they are crafted with a lightweight, yet still durable, bone structure.

[交互に骨体] Kōgo ni kottai | Alternating Bone Body
Only available to use after Hone no Yoroi is used. Shadow's body begins to take on various changes in conjunction with his sharingan active. Due to Shadow's increased ability to sense and detect an opponents moves beforehand to a degree he uses this advantage alongside his Shikotsumyaku.

Examples:

Once an enemy has an attack aimed to hit his body Shadow perceives the attack (and with help of his Sharingan) is able to swift protrude a sharp bone from the area that was to be hit.

If a hit does land on Shadow he can capture the enemies arm, leg, whatever they used by spiraling bones from his body to trap them inside said bones.

This technique is not without its setbacks. Due to the speed Shadow is manipulating his bone and the amount of changes he may need to use his chakra and body begin to wear down at a faster than normal rate making prolonged usage of this highly advised against.
