Sergeant Mech operates as the explosives specialist of the Roughnecks A-01 Team, an elite Mobile Infantry unit deployed for high-risk combat operations. Proficient in demolition and ordnance, he executes critical technical tasks under fire—rigging strategic detonations, restoring compromised systems, and breaching hostile environments during missions. Assigned to secure the engine room of the derelict starship *John A. Warden*, Mech adapts swiftly when the Arachnid Queen hijacks the vessel. Following evacuation orders, he partners with Ratzass to rig the engine room with timed charges, ensuring the ship’s destruction to thwart the enemy’s advance. Mech survives the operation alongside Ice Blonde and Ratzass, later joining them in a brief memorial for lost teammates. His role remains defined by technical precision and tactical execution, adhering strictly to unit protocols during combat engagements.
