Prime Master

The twelve Prime Masters may be small, but the power they hold is anything but – each one carries within them the spark of one of the original Primes, ancient gods of the Transformer race. By uniting with a larger 'bot, the Prime Masters can bestow upon them the powers of a Prime, making the small robots a hot commodity for Autobots and Decepticons alike. The nature of these abilities vary with every new combination, each combination adjusting to best merge the nature of the Prime Master with the temperament and personality of the 'bot in question.

To minimise this unwanted attention, the Prime Masters hide themselves inside special Decoy Armor, which cloaks their vast power from the outside world.
