Been a long time since I entered anything like this, so will see how I go.
Let me know if this is bending rules or isn't accepted within your plans.

Real name: Max Anderson / Maxine Anderson
Gender: Max = Male, Maxine = Female

Description: A single person with split personality and a physical transformation between them. The change between the personalities is not something either can control, however it can be triggered when the dominate personality becomes unconscious or goes to sleep. Max is 180cm tall, medium build, blue grey eyes and shoulder length black hair. He is a relatively quite person, who only speaks when necessary and holds a lot of pride in being honest, faithful and trustworthy. Maxine is 170cm tall, light build, sapphire blue eyes and shoulder length black hair with a white strip in her fringe to the left side. She is almost the polar opposite of Max, she is an over bearing person, who spits words like venom and is holds herself above anyone else.
History: Originally a single personality/person, Max being the dominant person until his 16th birthday, where he experienced a sudden loss of 4 days of his life. These missing 4 days was when Maxine first manifested and went on a crazed bender of violence, crime and egotripping. Ever since then there has been a constant struggle between the two to maintain control, to ensure they survive.
