Backstory: One of the signature techniques of the Sarutobi Weapon Monkey summons. Historically speaking, the most notable user of this technique was Monkey King Enma who had valiantly used the technique alongside Hiruzen Sarutobi in the defense of Konohagakure from various threats ranging from S rank Missing Ninja attacks to the Nine-Tailed Demon Fox.  


Appearance: There is a puff of smoke, within the smoke is the monkey summon that has transformed itself into a weapon. The exact size and dimensions of the weapon must be detailed in as it transforms.

What it does:  

Upon activating this technique the user transforms into a weapon of their choosing for their summoner to use. While historically this has been the form of a staff, the Weapon Monkeys are not limited to this form and can take on the forms of other weapons such as hammers, swords, axes, and so on (any weapon that is permitted by the rules and could be apped). This transformation happens at jutsu speed. This weapon's size and dimensions MUST be detailed upon use of this technique. The default weapon form turned into cannot exceed 3 meters in length and 1 meter in width, but may extend to larger sizes through the other features of this jutsu. 

While in this form, the Monkey's weapon form is as as hard as diamond, making it very destructive. This also renders it largely impervious to damage, making it useful as a defense. This incredible defensive nature of the technique is reflected by the weapon having an effective health stat equal to the health stat of this jutsu. Should an attack or opposing force have a power greater than the health stat of this jutsu, the damage will be subtracted from the health pool (HP) of the monkey summon and then forcibly end this transformation after it has been dealt damage, putting this technique immediately on cooldown. It should be noted that while in weapon form, the monkey has no "vital points" and if the clash is with something that would bisect or shatter the weapon (or similar), instead the monkey will simply take the damage to its health pool and de-transform with its whole body intact. These instances will not automatically kill the monkey summon. 

While transformed into a weapon, the monkey can be used like any other weapon would be. You can use it for Weaponry spec jutsu as long as that Weaponry technique could be used while wielding whatever sort of weapon the monkey has transformed into. 

The weapon is also able to extend to great lengths, enlarging itself by 25 meters at A rank, or 50 meters at S rank. This extension happens at Jutsu speed. 

The user (monkey summon) can choose to produce any part of his regular body from the weapon. This includes (but is not limited to) arms, eyes, claws, legs, fangs. These parts appear at jutsu speed. 

While using this technique, the weapon monkey can move at jutsu speed through the air of its own will and power. This is typically used to ensure that the Sarutobi is never disarmed. The use of this technique alone CANNOT allow the Weapon Monkey to "telekinetically" move to strike a target from a distance. The weapon monkey uses this feature of the technique to return to its summoner by positioning itself to be within the summoning Sarutobi's grasp. This feature only works while within 30 meters of the summoner at A rank, or within 50 meters of the summoner at S rank.

Edits were made per discussion on discord:

Concern regarding maximum initial dimensions was brought up. As requested, I have limited the initial dimensions of the weapon. The initial transformation now cannot exceed 3 meters in length and 1 meter in width. Retained language regarding the users need to make very clear the weapons initial dimensions upon the transformation. 

Discussed my thought process behind the defensive nature of this technique. After discussion determined that it was okay in current state. 

Was asked to put in a range limit on the monkey's ability to fly through the air back to their summoner. Came to terms to limit it to 30meters at A rank, and 50 meters at S rank to match the extension sizes.
