Marco Inaros
The first time we witnessed Marco was in the fourth season. He is the leader of an extremist cell of the OPA. All this while, he refuses to join the rest of the leaders in forming a unified Belter Government that he thinks is perceiving as kotowing to Earth as well as Mars. The man is dubbed as a violent terrorist and has proven himself to be a threat.
Filip Inaros
Filip is the teenage son of Marco as well as Naomi. He was born when both of his parents were roughly his age. Marco raised up his son and thus, he loyally follows the cause of his father. Although, he barely knows his mother because she left in order to escape Marco. Not much is known about the true intentions of Filip but at this point in time, he appears to be a firm believer in the vision that Marco has seen for the Belt. Although, if he ever happens to meet his mother, all his beliefs would be set in for a challenge.
Camina Drummer
We have seen that Camina has previously worked for the faction of Fred Johnson of the OPA. She has helped him create the Nauvoo which is a colossal colony ship meant for the Mormons. Although, his loyalty to Fred Johnson becomes strained when she was ordered to use the Nauvoo in the form of a battering ram. It was all done in a failed attempt to divert Eris station which was injected with the Protomolecule.
Fred Johnson
This character used to be a Marine Colonel in the U.N. He dedicated all his service to Earth while fighting Belter Pirates. Although, after leading a mission against insurgents that proved fatal to thousands of civilians, he came to be known as The Butcher of Anderson Station. He was filled with shame as well as self-loathing despite the appraises that he received from Earth.
Clarissa Mao
She is the eldest daughter of the Protomolecule conspirator as well as industrialist, that is, Jules Pierre Mao. This character was first brought to light back in the third installment. She is highly affected by the downfall of her family and thus, blames the Rocinante crew for the change in fate. This is when we acknowledge her getting a false identity in the form of an engineer on the board of a UN warship. This is when she planted explosives on the ship and thus, ruined the vessel. Holden was farmed for the attack by her. This made him look as if he was siding with OPA. Continue Reading: Best Drummers of All Time – Top List
