Filip is the first and only son of Naomi Nagata and Marco Inaros, born on Ceres after a difficult pregnancy due to the dangers of low gravity, Filip was raised lovingly by his parents during his very early life, however after the destruction of the transport Augustin Gamarra by his father, his mother's guilt of her involvement made her severely depressed and unstable so his father manipulatively hid Filip away from her to keep her silence and "good behaviour". His mother then tried to take her own life to escape his father's radical beliefs and manipulations, and eventually she had no choice but to abandon Filip and leave him with his father and her former crew.
Destruction of EarthEdit
In Nemesis Games' Prologue. Filip, now a full member of his father's radical faction of the OPA led an assault on the MCRN shipyards on Callisto, using timed asteroid impacts and sacrificing his own team members as a distraction, Filip and his team raided a Martian supply depot for High Density Resonance Coating.
After the raid, Filip was apparently hiding from the authorities when his father contacted his estranged mother Naomi Nagata to help smuggle him and several others off Ceres. When his mother arrived on Ceres, Filip showed disappointment in that she did not bring the Rocinante with her.
After a few days hiding in an OPA safehouse, his mother managed to acquire a ragtag ship called the Chetzemoka to get them off Ceres and told Filip that once he was safe it was his to do as he wished, however unbeknownst to his mother Filip was there as a lure so she could be kidnapped and taken back to Marco Inaros in an apparent plan to keep her safe from what was about to happen because she was one of "them" — a member of the in-tribe, a Belter, or perhaps simply someone Marco wanted to own.
After reuniting his mother with his father aboard his ship the Pella, the Free Navy were hiding in the Hungaria Asteroids near Mars orbit, when they were discovered by the Razorback. The Free Navy, not yet ready to carry out their plans, tried to destroy the Razorback before those aboard the racing pinnace could alert anyone of their presence; however, the Razorback was saved by the nearby Martian fleet escorting Prime Minister Nathan Smith to Luna.
After the asteroids that were hurtled towards Earth devastated the entire planet, Filip and everyone on board celebrated and cheered as the newsfeeds started coming in of the destruction and he was proud of his involvement and even boasted to his mother that all this was "his work". Naomi Nagata after discovering that Filip was involved in the attack on Earth was deeply ashamed and scolded Filip which deeply hurt him although he tried to hide it and stormed off.
Filip, under the urging and nudging from his father Marco, is rolled up in the creation of the Free Navy. His father expects him to act and carry himself a certain way. Filip during a surprise attack on the Rocinante, is given the privilege of being the gunner for the Pella. He fails to deliver and even though it's a 3 on 1 attack, their own ship is wounded and forced to pull back. Filip. It is unclear whether Filip would have had the will to knowingly kill the vessel that his mother was on. After this, Marco is noticeably disappointed and ashamed of Filip. Filip takes this to heart and learns that his own father has been talking behind his back saying that the attack on the Roci failed due to Filip's lack of courage, will and strength.
Filip is feeling down and out after his father's verbal abuse of him. He finds himself back on Callisto, the same Callisto that he and the Free Navy had broken into and attacked and looted years back when the Free Navy first formed. His first mission. He meets up with Karal by chance in one of the bars and they talk. Karal, again proves to be more of a supportive father type to Filip than Marco is. On the news feed they see that Fred Johnson was killed in their attack.
Back on the Pella, there's a huge party going on to celebrate the news. Marco is now jubilant and happy, and over the din of the party, mouths the words "We did it". This infuriates Filip as he now is being *shared* in the triumph, but was alone and singled out, when it was a defeat.
When the coordinated attack by the Combined Fleet begins against Marco's forces, Marco calls his leaders to report to him on Callisto. Filip, present at the meeting, speaks up and asks whether Marco will find a way to turn even this loss into a defeat somehow and pretend, like with the other "strategic retreats", whether it was "all part of the plan." Marco embarrasses Filip by acting as if the questions are the result of Filip being "a boy" and not mature enough to understand the plan. Filip leaves in a huff.
Later, Filip is in a karaoke bar, discussing the attack on Callisto (which he led) with a local and asking what had happened with the Belters. Realizing that Belters had lost people in the attack, Filip begins to recognize the losses he has incurred on behalf of Marco. After leaving the bar, Filip begins to see that Marco has manipulated everything in his Filip's life the way he manipulated the defeat at the hands of the Rocinante into a victory. He answers a call from the Pella, only to hear directly from Marco that the Pella and the rest of the combined fleet are going to be burning for Medina Station to hunt down Holden and Naomi and that Filip has to return to the ship in a half-hour. Filip feigns excitement. Then, he drops his gun and communicator into the recycler and signs on as a workman at the local employment office, missing the launch time for the Pella and avoiding being on board when the remainder of the Free Navy are killed by the Gate.
