Androids (人造人間, Jinzōningen; lit. “Artificial Human”) are robotic/cyborg humans, most of which were created by the evil scientist Dr. Gero. Most of the androids are said to have unlimited energy and eternal life. Due to their inorganic nature, they, or at least the ones created by Dr. Gero, also have no detectable aura (unlike Saiyans, Humans, and others), so they cannot be directly tracked using Scouters or Ki Sense. There are at least 6 units shown to have been fully functional throughout the original Dragon Ball manga.
