Beta Maxx, also known as B-Maxx, Alpha Trion's tiny, enigmatic companion, has dedicated himself to discovering the reason Cybertronian life came into existence. He is presumed to have been created during the Golden Age, though the identity of his creator is unknown. Beta Maxx was constructed with a vast data-storage capacity, and his spacecraft alt-mode can be used as a Key to Vector Sigma. He is the keeper of a secret codex that can translate ancient Cybertronian texts, and he can interface with many archaic computer systems.
