The bots who devoted their lives to healing/repairing other bots. This Guild is rather new as Vandoricons have only relatively recently realized that their inner structures are organic in a sense.
Medicons are doctors, they also serve as field medics and rescue workers.
Medicons typically are in white and red and bear a Y like character on their shoulders. They generally transform into a transport or a plane.
The Medicons were originally just a branch of the Science Guild, composed of scientists who became interested in studying their new Transmetal physiology. They also incorporated the Clericon caretakers of New Born Vandoricons and came together to form the Medical Guild.
