Metalhawk

Metalhawk (メタルホーク Metaruhōku) is the leader of the Autobot Pretenders. With the power to disguise themselves as humans, they defended early humankind against the Decepticon Pretenders who took the forms of monsters. They eventually defeated and sealed away the villains, inspiring a few myths in the process, and went on to help guide the evolution of Earth's society and culture.

By the early 21st century, Metalhawk had adopted the simple human alias of Hawk (ホーク Hōku), and now works as an astrophysicist at the observatory run by Professor Gō. He is close friends with both the professor, with whom he has entrusted the secret of his true identity, and with the professor's son Shūta.
