Master


 * Master is a planet in the Generation 1 continuity family.

Planet Master is an alien world with insane and murderous weather conditions. Naturally, a group of Autobots and Decepticons fleeing the war on Cybertron thought it would be a phenominal place to spend the next 4 million years.

The Headmasters animated series and manga
Not happy with a war which never seemed to end, a group of diminuitive Transformers, both Autobot and Decepticon, fled Cybertron in search of a new crib. Their travels brought them to planet Master. The weather conditions on Master were crazy-fierce, with ice ages burying them in a frozen wasteland for centuries to scorching heatwaves that baked them like Shrinky Dinks. Never-the-less, the Transformers decided that instead of ditching the killer planet, they would learn to adapt.

They developed the Headmaster process which allowed the Transformers to transform into heads and then attach themselves to larger bodies called transtectors. This allowed them to survive the harsh conditions of Master for millions of years until they all finally got sick of it and left.
