Rikiddo Unabara

Background
Rikiddo has been called the Assassin of the Hidden Mist; this is because during his childhood, he had killed over 1000 of the ninja academy graduates attending their final exam. In the exam each student would be pitted against the other in a battle to the death. His fame grew over the years, as he became both an Jonin and a member of the Seven Ninja Swordsmen of the Mist. He eventually attempted to kill the Daimyo, and subsequently fled. Just before leaving the Village he discovered his kekkai genkai, that allowed him to combine the wind and water elements to bring forth ice. He began training to be the ultimate weapon.

Weapons & Abilities
As his nickname suggests, Rikiddo is a very vicious battler, preferring more direct attacks than deception with strong taijutsu skill. However, despite Rikiddo's aggressive nature, he has shown to be a crafty ninja capable of misdirecting his opponent. His signature and weapon of choice is the Giant Decapitating Carving Knife, an oversized, broad sword that was wielded by Zabuza Momochi. The sheer size of this blade demonstrates great physical strength on Rikiddo.

The circle cut out of the top and the semicircle near the handle, as demonstrated by Rikiddo later, seem to fit its purpose of decapitation aptly. Its handle also appears to be retractable, as its handle is very short when shown on Rikiddo's back but becomes significantly longer by about four times when he fights with it.

Likely in part due to him being from the Hidden Mist, Rikiddo seems to prefer water manipulation techniques and has shown great skill in them. Having trained for years, Rikiddo has become a very dangerous ninja for his age. Rikiddo possesses very detailed knowledge of human physiology. His knowledge was great enough to that he could disable an opponent from action by hitting a precise point on the body with a senbon to cause immediate death or the a temporary appearance of such.

In battle, Rikiddo fights with tremendous speed and dexterity, possibly with assistance from his wind-chakra reducing wind resistance. His speed is great enough that his movements cannot be seen with untrained eyes. Rikiddo's preferred battle tactics revolve around the usage of ice jutsu.

Rikiddo's most noticeable power is the utilize water and wind-chakra to create ice. His power over ice grants him very powerful techniques.

Rikiddo is also very keen minded as he has shown great observational and analytical abilities, capable of quickly determining a way around an opponent's technique or strategy. Rikiddo also had the ability to perform Hand Seals with only one hand.
