I'm basically making this up as I go, so if there are a couple inconsistencies forgive me.

Here we have a pair of advanced cyborg twins for futuristic or sci-fi genres.

Name: Cristoff Nickname: Cris Codename: Crimson Personality: Cris behaves slightly more carefree than his brother. Often he will be headstrong and rush into a situation without properly analyzing it. He has more of an interest in humans and learning to behave like one. He likes to watch television to learn as much about human society as possible.

Name: Soran Nickname: Sor, Sunny Codename: Sunrise Personality: Soran is the more serious of the two. He relies on logic and intelligence to determine the best course of action. He views himself and his brother as set apart from humanity despite their organic components and finds their lessons in how to behave and blend in pointless.

(Shared Information) Actual Age: 3 Apparent Age: 19-23 Appearance: Cris and Soran are twins, alike in every way except their coloring. Cristoff has red hair and green eyes; Soran has blond hair and hazel eyes. They wear their hair cut short and appear to be in their early adulthood. Both are in top physical condition, with muscular bodies resembling those of trained martial artists. Despite being artificial life forms, they appear nearly indistinguishable from humans.

Biography: Cris and Soran were not born, but built. They are a pair of highly advanced bio-mechanical androids built by the government and military. They are programed with artificial intelligence and "real person" personalities. They are both prototypes, and no other like them is known to exist. The reason for their creation and development is to serve as soldiers and spies as the territories of outer space become more accessible to people of this world.

Only three years old, the twins still have things to learn about what it means to be human. They have spent the majority of their lives among military personnel and the scientists who built them. Because of this their human interaction has been limited. However, they have been trained in numerous martial arts and warfare techniques.

Cris and Soran have never needed to attend school, as technical and data information can be downloaded into their circuitry. However, they are taught about human culture and society. Until they are able to successfully integrate with real humans they will not be allowed off of the military base where they have always lived.

Their development program is classified under the codename "Crimson Sunrise". Few people outside the military base and labs know of their existence. Fewer know that they are not human.
