Appearance: Androids have multiple appearances, as most of the major planets have the capabilities of creating them. In recent history, Androids modeled after humans have been recorded as well as Saiyan instances. Androids can be built from the ground up or they can be modified humanoids whom were rebuilt as them for various reasons.
Background: Androids have many different backgrounds and purposes. Some are built with destruction and dominance in mind, whilst others are built as companions for their creators and some are built with the purpose of defending their base race from harm. Because of this, Androids have varying backgrounds.
