Androids have bionic metal skeletons that allow them to move. They are usually human-colored and bipedal. Generic androids are comprised of nothing but the skeleton, while others have outer shells. Some androids look identical to humans, such as Chris Wellington.
Several years prior to the Great War, inventors Gabriel and Luther Arsene of Alchemists Co. (later Alchemilia Corporation) created "Eric," a powerful robotic combat machine. The development of Eric led the two to become world-renowned in the robotics field. Shortly after Eric's creation, Alchemists Co. mass-produced androids for military purposes.
Around the two brothers' rise to fame, Andrew Wellington stole Alchemist blue-prints for future android models. Andrew left the company and established a competitor, "Wellington Robotics," where he went on to create his own models. Andrew made an initial nine androids based on the Alchemilia blueprints, starting with Charles Wellington in 5980 AT and ending with Chris Wellington in 5993 AT. In 5994 AT, Andrew realized that Chris' unusual ability to feel emotions was the perfect tool for distinguishing himself from his former boss, and set to work making a factory in Skipton, where he produced many more androids with this trait. Unfortunately, demon and angel attacks on his factory starting in 1 TP rendered Andrew's efforts at making good creations useless, and he soon quit the industry altogether.
Most Alchemilia androids have physical abilities that surpass the average human. Their ability to be programmed makes them an effective tool in war.
The original 9 androids built by Andrew Wellington all have super-strength, concealed weapons, and one additional ability, such as Chris Wellington's ability to smell. Later models are more like Alchemilia Corporation's, but also have emotions.
Most androids run on an artificial intelligence software that make them extremely versatile. Only a few are fully sentient, however.
