Alphonse (Fullmetal Alchemist)

While technically a suit of armor housing a human soul, Alphonse Elric functions as the ultimate 'robot' archetype in terms of physical durability and mechanical movement. His existence raises profound questions about the nature of the body versus the soul. Alphonse is a gentle, highly skilled combatant who serves as the moral compass of his series. His design is simple yet evocative, representing the tragedy of lost humanity.

He is a must-watch for those who appreciate character-driven narratives where the 'machine' is more human than the people around him.
