Micromaster

Micromasters are a subspecies of Cybertronians from the Earth-like planet Micro. They are sometimes known as Devisens and come from the planet Devisiun.

Anatomy
Micromasters share a similar biology to other Cybertronians, though they are small and roughly human-sized in robot mode. Their bodies are extremely fuel-efficient, and they usually transform into tiny cars, planes, and other vehicles.

Similar to regular Cybertronians, some Micromasters are Combiners. One known type is the Micromaster Combiners, who can each form either the front or back half of a combined vehicle. They are not constrained to joining only with their Combiner partner, as they can join with any other as well as to the back of any Micro Trailer.

Another known type is the Combi-Micromasters, who combine in another humanoid robot. While no one has ever been specifically designated as a Combi-Micromaster, the description at least fits the members of the Multiforce.

Culture and society
Unlike other planets inhabited by Cybertronians, Micro is actually quite a nice place to live by galactic standards, possessing a breathable atmosphere, and plenty of greenery and natural water sources around which the planet's cities are built.

Each Micromaster forged on Devisiun emerged with a twin sibling, where each formed half of a single alternate mode, although they were not "combiners" in the true sense of the word. This mutation was supposedly caused by the intense gravitational forces of Devisiun's twin suns. The bond between Devisen twins is so close that they frequently finished one another's sentences.

Technology
Micro's cities are especially technologically advanced, with one third of the planet's power being supplied by an experimental plasma energy plant.

Religion
Devisens are associated with Nexus Prime.

History
Some Micromasters were created as being small while others started off as ordinary "guzzlers", the term used by Micromasters to call normal-sized Cybertronians before being rebuilt into Micromasters.
