Ok, here's my character that I'm putting up for consideration.
Name: Kuroda Uchiha
Appearance: Just picture him in they standard Jonin outfit and vest.
Elemental Chakra: Fire, Wind
Specialization: Taijutsu, fire and wind ninjutsu. He is able to use the others thanks to his Sharingan, but it takes more chakra to use techniques that are not fire or wind.
Bio: Over the past 500 years, the Uchiha clan has slowly rebuilt itself to it's former glory. While many citizens of Konoha were against this at first, the Sharingan was considered too valuable to be lost. The Uchiha clan was eventually accepted, and is now respected in Konoha and throughout the world.
Kuroda is the nephew of the current head of the Uchiha clan. He is kind and humble, knowing that just because he was born into a clan of high status doesn't automatically make him better or more important than any one else.
From a young age, he was shown to have great potential. Kuroda graduated from the academy early, and he was able to activate his Sharingan at the age of 13, on his first mission outside of the village. At the age of 16, he was offered a position in the ANBU, but declined for personal reasons. He became a Jounin a year later, and has proven himself a talented ninja many times over.
