Personality and Background
Michael fits the archetype of the seen-it-all soldier: someone who has been through enough conflicts and institutional betrayals to view the world with a weary, clear-eyed pragmatism. He is principled at his core, holding firm beliefs about right and wrong, but those principles have been tested repeatedly by the realities of military service and private security work.

His career began in the United Nations military, where he served as a soldier in Earth's armed forces. The specifics of what he saw during his service are part of his personal storyline, but the result is clear: Michael grew disillusioned with the system. He witnessed institutional failures that could not be explained away as isolated incidents, and he came to question whether the UN's military apparatus was truly serving the people it claimed to protect.
After leaving the military, Michael moved into private security, which brought its own set of compromises. Working as a hired gun for corporate or governmental clients further eroded his faith in established power structures. By the time he joins the Gemini's crew, Michael is a man struggling with past tragedies and searching for a cause he can believe in without reservation.
Michael has been described as a rival mercenary working for a competitor, which suggests his initial relationship with the player character may involve professional tension or even direct conflict before circumstances bring them together as allies.
Combat Role and Abilities
Michael operates under the Demolition exploit category, the same category as Polly. His specialty is destroying cover and terrain outright, forcing enemies out of defensive positions and into the open where they can be engaged directly.

Michael's combat style is the most aggressively frontal of any companion. He carries a shield that provides personal protection while advancing, and a shoulder-mounted autocannon that delivers sustained heavy fire. This combination allows him to push forward into enemy formations, absorbing incoming damage with his shield while his autocannon tears apart cover, barriers, and enemies alike.
The destruction that Michael's loadout produces serves a dual purpose. First, it deals significant direct damage to any enemies caught in the open. Second, it systematically removes the cover that enemies are hiding behind, denying them safe positions and forcing them to either flee or fight exposed. In tight corridors or confined spaces, Michael's autocannon can reshape the entire battlefield within seconds.
Weapons and Equipment
Equipment | Description |
|---|---|
Personal Shield | A handheld defensive barrier that absorbs incoming fire while Michael advances. Allows him to push through killzones that would stop unshielded companions. |
Shoulder-Mounted Autocannon | A heavy automatic weapon mounted on Michael's shoulder that fires independently of his shield arm. Delivers sustained fire capable of destroying cover, barriers, and armored targets. |
Heavy Armor | Michael's loadout includes substantial body armor that, combined with his shield, makes him the most durable frontline companion in the crew. |
Disillusionment and Principles
Michael's disillusionment is not the same as cynicism. He still holds strong moral principles; the problem is that every institution he has served has eventually betrayed those principles. The UN military let him down. Private security work required compromises he was not comfortable making. These experiences have left him questioning not just specific organizations but the very concept of institutional authority.

His questioning of UN institutional failures resonates with the broader political themes of The Expanse universe, where Earth's government is shown to be powerful but often ineffective, corrupt, or indifferent to the suffering it causes. Michael's personal experience gives these abstract political themes a concrete, human face.
Relationships
Michael's background as a rival mercenary suggests that his relationship with the player character has a history that predates the events of the game. Whether they were competitors for the same contracts, opponents on different sides of a conflict, or simply aware of each other's reputations, this prior connection gives their dynamic an edge that other companion relationships lack.
Within the crew, Michael's military experience and principled nature earn him a certain level of respect. He is someone who has been tested in ways that most people have not, and his willingness to question authority rather than follow orders blindly appeals to crew members who share his skepticism of established power structures.
Tactical Notes
Michael is your primary frontline tank. Use his shield to absorb fire while advancing through open ground or pushing through chokepoints.
His shoulder-mounted autocannon deals heavy sustained damage. Position him where he has clear sightlines to enemy cover positions, and let his Demolition exploit do the work of flushing them out.
Michael and Polly share the Demolition exploit category. Choose between them based on the engagement: Michael for aggressive pushes and tanking, Polly for mobile flanking and explosive support.
Pair Michael with a healer or support companion. His frontline playstyle means he takes significant damage, so having Teo nearby to keep him fighting extends his effectiveness dramatically.
In wide-open environments, Michael's shield and autocannon make him less effective because enemies can simply reposition around him. He shines most in corridors, rooms, and confined spaces where his ability to destroy cover creates unavoidable kill zones.
His heavy loadout makes him slower than other companions. Plan your positioning in advance rather than trying to reposition him mid-fight.
