Filip Nagata, formerly Filip Inaros, is the teenage son of Marco Inaros and Naomi Nagata.



As a baby, Filip was abandoned by Naomi, and was later kept hidden from her by Marco with aid from Cyn.


He continually seeks approval and recognition from Marco, and harbors much resentment and indifference towards Naomi for her abandoning him, which had most certainly been exacerbated by Marco. Filip is capable of murder as seen on multiple occasions, especially Inners, and has even attempted to kill Naomi in some instances. This behavior may be rooted in his upbringing by his father, the harsh reality of Belter life, or is simply motivated in seeking his father’s approval.

Despite this, Filip is far from bloodthirsty and grows weary of killing senselessly, and his enmity towards Naomi never reached a point where he wanted to kill her outside of reluctant compliance to Marco. He becomes increasingly disillusioned with his father's actions as the Free Navy conflict escalates, realizing that Naomi was correct about Marco's character, and eventually abandons him out of disgust for his indifference towards Rosenfeld's death.

Throughout the series[]

Filip is seen being the person who gets the Martian stealth tech out of Mars and planted the bomb in the dome. Bobbie shoots at him but he escapes, right before the dome collapses.

After Ashford breaches Inaros' ship and has Marco at gunpoint, Filip arrives. He witnesses Marco putting Ashford out an airlock.

⑩-"Nemesis Games" · There is still more to do[]
