Maximal

Maximals are a subspecies or faction of Cybertronians from the planet Cybertron.

Anatomy
Maximals share a similar biology to other Cybertronians. While they generally transform into mammals, birds, and aquatic life, this is not a hard-and-fast rule. Occasionally, Maximals might choose to become insects, reptiles, or dinosaurs.

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

Weaknesses
Maximals share many of the same weaknesses as other Cybertronians.

Culture and society
Arising from the ashes of the Great War, Maximals are generally considered to be the descendants of the Autobots, controlling Cybertron under the Pax Cybertronia. The Maximals owe their origins to the Great Upgrade, which provided the downsized, fuel-efficient bodies that became the hallmark of both them and their counterparts, the Predacons.

In many ways, the Maximals share traits with their Autobot ancestors. Primarily a "civilian" race, the Maximals are committed to upholding the peaceful, democratic values of their forebears. They are generally led by Optimus Primal.

All this said, Maximals are not perfect as they still have their jerks. Additionally, Maximal science has occasionally resulted in the odd unethical scientific horrors.

The most distinctive factor of Maximal physiology is their development of pseudo-organic beast modes, allowing them to adopt alternate modes that blend in seamlessly with the organic lifeforms found elsewhere in the universe. This technology, an offshoot of earlier Pretender tech, sheathes a beast mode in an artificial organic skin, integrating its natural instincts directly into the Maximal form.
