Upgrade Key

Name: Upgrade Key
Looks:
Description: Josh's dad was always a genius. One of the smartest in Konoha, but he also a VERY great mechanical scientist. He worked for years on a special way of upgrading Desomaru until he finished the Upgrade Key. He knew the very high risks of using it, and so he hid it deep within his laboratory where noone could ever find it. However, after his father died Josh explored his dad's laboratory and eventually discovered the upgrade key, and it's uses.
Effects: When it is hooked to Desomaru's forehead he will undergo transformation that cause him to look like this when it's finished.

Abilities: Using his wings and rocket boosters he can fly at incredible speeds, his hands can transform into drills, hammers, or extend into razor sharp claws. He can also still breath fire from his mouth, but can also blast fire from his hands. Because his form is so superior in this form his defense is even greater, as are his punches, and his combat style is upgraded to fit that of a very skilled ANBU, or Jounin.

Costs: When Josh attaches this upgrade key to Desomaru it instantly sucks in half of his usual chakra to securely power the upgrade, and even a large proportion of it is simply stored inside of Desomaru. As well as this Josh and Desomaru also form a telekenetic bond, and can talk to each other through thinking, but the downside is that if Desomaru is injured, or killed Josh will take the same damage except two times as bad. Because of this, this upgrade key is rarely used. Another cost is that if Desomaru does not get changed back by the upgrade key within ten hours of starting use, he will die, and once again the same will happen to Josh.

((Sorry, if it seems a little too futuristic.))
