I'll post one of my two OCs up here since everyone has posted up theirs.

Name: Deiara Uchiha
Gender: Female
Age: 13
Bloodline: Uchiha clan's bloodline of the sharingan, yet she never likes to use it at all. She regrets being apart of the Uchiha clan so she hides her bloodline trait, yet occasionally her sharingan is released without her knowing.
Hair color: Light brown (bleached by the sunlight)
Eye Color: Blue (This is one of the ways people cannot tell she's an Uchiha until they turn red)
Weapon: Katana, summoning fox named Kitsune and clay bombs
Personality: Serious, withdrawn, yet kind to others
Relationships: None
Friends: Naruto, Hitachi, Tatsuma, Deidara, Tobi, and Sasori (kinda)
Rivals: Hitachi and Tatsuma
Notiable Traits: She wears a sharingan necklace and never takes it off although she hates her sharingan. She always wears her hair up except at night.
Past/ Life story: Deiara was four when all the Uchiha clan was killed. (Her dad was one of them) Her mother abandoned her to live with Naruto. Deiara however left Naruto's house and didn't return. She then went and lived with the Inuzuka clan where she met her friend Hitachi.
In the ninja Academy she was assigned to be partners with Hitachi and Tatsuma. She was kind towards them, but they never got along so she often had to keep them away from each other. The team didn't last though. She, Hitachi, and Tatsuma soon joined the Akatsuki after being forcibly recruited by Itachi.
She now trains under the guidance of Deidara and is learning how to create clay bombs.
