Transformer Planet
Cybertron. The planet in which the Transformers originated. The "Steel Planet".
Iacon Hub City is its capital, which the Autobots call home. The Decepticons are based in Kaon. Other places of interest are Perihex, Antihex, Uraya, Polyhex, Vos, Tarn, Nova Cronum and crystal city (destroyed).
In the Beast Wars saga, Cybertropolis replaced Iacon as the Autobots' base.
In the original cartoons, Cybertron is a small planet used by the Quintessons to make their assembly line of workers and soldiers. In time, the workers and soldiers rebelled, with the workers becoming the Autobots and the soldiers, the Decepticons.
Cybertron is metallic on the surface, but go deeper and you'll find the rocky interior. Its gravity is light enough for humans to walk with ease and Cybertron posesses an atmosphere.
The planet also plays to an assortment of fauna, namely, ant-droids, bolt-bats, cyber-ducks, dynametal ducks, electro-toads, glitch-mice, guineapigatrons, helio-hamsters, hydro-weasels, photovoltaic pussycats, retro-rats, robo-rats, sheepacrons, titanium moose-bots, turbo-foxes, zap-mice and robotopossums.
