–Mike as he watches his former co-centurion inadvertently launch himself at Gaea in, The Blood of Olympus.
Michael grew up in Hilo, Hawaii where he was a linebacker in high school.
Joining the Twelfth
Michael was in a dream talking to Octavian about his decision to reinstate Bryce Lawrence.
Michael appears in a speedboat with Leila and Dakota to arrest Reyna and Nico. After a brief fight with Coach Hedge, he was knocked out by Tyson as he and Ella came to help Nico and Coach Hedge. Nico di Angelo, Dakota and Leila drag him to shore and leave him by the docks, not binding him because it would sway his loyalties.
The son of Venus is mentioned to have been selected to lead a boarding party onto the Julia Drusilla Yachts and a few days later sets out to perform the task. His team fails but their task is successfully completed when Lavinia Asimov and a group of nature spirits destroy the enemy fleet. It is unknown if he survived the Battle of San Francisco Bay or not but it is possible as Lavinia states that her assault was also to rescue Michael and his boarding party.
Mike is extremely loyal to the Twelfth Legion Fulminata. He obeys his superiors no matter who they are. Despite his loyalty to Octavian, he is shown to doubt his plans and Reyna believes his heart is in the right place even if he makes poor decisions. Towards the end, his loyalty falters and he later purposefully lets Octavian kill himself to end his madness, showing his loyalty lays with the legion itself and not its commanders.
Mike is a teenager of Native Hawaiian decent with dark hair and eyes, a tan skin and muscular arms. His tattoo is a dove, one of Venus' sacred animals. He also has arms as thick as bridge cables.
