Fortress Maximus

1. Size: A colossal Transformer — roughly the height of a skyscraper. One of the largest Autobots.

2. Alternate Modes: Transforms into a battle station or space fortress, and sometimes into a tank or ship, depending on the continuity.

3. Color Scheme: Predominantly blue, gray, and red, with neon green or yellow highlights (e.g., on windows or weaponry).

4. Head: His head is a separate Transformer named Cerebros, who can also house a smaller unit — often Spike (in some versions).

5. Weapons: Equipped with massive shoulder cannons, blasters, and turret-based weapons. He can launch missiles or energy beams.

6. Details: He has a heavily armored, architectural body structure, reflecting his ability to become a fortress. His chest and shoulders are broad, and his legs are thick and reinforced.

7. Eyes: Typically glow blue or white, enhancing his stern, mechanical appearance.

Serious and principled: He has a strong sense of justice and responsibility. Believes deeply in law and order.

Traumatized by the past: In the IDW comics, he carries deep psychological scars from the war and imprisonment in Garrus-9.

Reserved and distrustful: Often distant in conversations, slow to trust others. Though he may appear cold, he genuinely cares about life and protecting others.

Leadership qualities: Capable of taking command, though he doesn’t seek power. He often serves as a strategist or defender rather than an aggressor.

Psychologically vulnerable: His internal struggle between duty and personal trauma adds depth and emotional weight to his character.
