Headmaster

Headmasters (also known as Titan Masters) are a subspecies of Cybertronians from the planet Cybertron.

Anatomy
Headmasters are small symbiotic Cybertronian-like lifeforms that transform into the heads of larger robots. They are frequently but not exclusively organic.

Powers and abilities
Headmasters share many of the same abilities as other Cybertronians.

During a Headmaster procedure, the smaller partner gains control of a larger and more powerful body, whereas the Transformer gains an extra perspective on the battlefield. This psychic binary bonding allows them to draw on both their own ideas, tactics, and instincts as well as those of their smaller partner as quickly as if they were coming from their own head.

A Titan Master procedure behaves similarly to the Headmaster procedure, except the Titan Master also possesses a unique Spark that allows them to transfer their innate powers into the bodies of larger Cybertronians.

Culture and society
Headmaster bonding typically occurs between two sentient beings, but there have been cases in which either the head or body is a Transtector, a non-sentient construct controlled entirely by the other partner.

Titan Masters function similarly to Headmasters except they are additionally compatible with Titans.
