Charismatic and ruthless leader of the Free Navy, a radical Belter faction. Responsible for the asteroid strike on Earth that kills billions. A man of genuine political grievance and monstrous methods, whose belief in his own vision is absolute and whose love for his son is the only thing that complicates his certainty.

Son of Marco Inaros and Naomi Nagata. A teenager who has grown up entirely within the Free Navy and his father's ideology, and who must find his own identity in its shadow. One of the most psychologically complex characters in the later books.
