For the first and second seasons of the show, Marcus is partnered with Derek Peterson. Although killed off in the final moments of the season two finale, Marcus will play a pivotal role in Season Three, motivating Derek's actions through hallucinations.

Drug Addiction and Cynthia's Death
Marcus was a member of S-Unit, but the job had gotten to him, causing him to get into drugs and ingoring his girlfriend, Cynthia Solomos. Cynthia tried to convince him that what he was doing was wrong and that he should quit the force due to pressure. Marcus' life, due to not listening to Cynthia, went down hill. Cynthia was kidnapped by Roman Duke and murdered by, who Marcus believed, was Roman. Marcus was distraught for many years, continuously taking drugs. He was assigned to Derek Peterson as his partner in 2010.

Partners with Derek
In 2010, Derek and marcus were assigned as partners, as a way, the commissioner believed, of helping Marcus with Cynthia's death and Derek with Kale's. In 2011, Marcus and Derek discovered a number of drug related deaths that led them to a confrontation with Mr Greene.

In 2011, Derek found a lead on the drug case and him and Marcus entered a reported drug house. Finding nothing there, they also found a screen displaying Derek's house blowing up. Determined he was onto something, Derek moved into Marcus' to work on the case. After some hours working on the case, Derek and Marcus went to lunch where they encountered a man who opened fire at them. After pursuing the suspect back to Marcus' house, Derek arrested him and questioned him, learning of his employer named Lucas Greene. The illusive Mr Greene had planned for Derek's house to be destroyed, claiming that Derek was getting to close to something big. Mr Greene rang Derek and told him to back off. The suspect was also shot from the distance by an unknown shooter. Determined to arrest Mr Greene, Derek headed to Sydney to talk to one of Greene's previous employers, Allan Faraday. Derek learnt from Allan that Greene was a big time drug lord and imported drugs into the countryt through major planting foundations. After receiving an address, Derek went back to Brisbane to find Greene. Derek and Marcus headed to the address and encountered Greene. They arrested Greene, however claiming later and learning that the man they arrested was not actually Mr Greene, but rather a decoy.

Derek then worked with Marcus on several other cases. Six months after the first encounter with Mr Greene, Derek worked on a case involving the man who killed Cynthia, Marcus' girlfriend. Derek helped Marcus to come to terms with her death and arrested Roman. Derek also learnt from Greene's decoy, Jackson Grant, that Greene will reveal himself to Derek when he wants to. Derek also claimed to Marcus that maybe Roman wasn't actually Cynthia's killer, and that the real killer may in fact still be out in the world.

Another case Derek worked on with Marcus was the kidnapping of Cassandra Blake. Derek and Marcus found the kidnapper, however at great cost Marcus was shot and supposably killed.

Undercover
Upon Marcus' supposed death, he actually was assigned a top secret mission to infiltraite one of Mr Greene's work places and pose as a worker, gaining information on Greene's business and ultimately discovering his location. Marcus returned to Derek and informed him where Greene was.

Going After Greene
Marcus and Derek then arrested Mr Greene and were informed that if he wasn't released, that bombs would detonate around the city. Determined to stop Greene but unable to do so, Marcus and Derek were forced to release Greene. When Greene didn't keep his promise, Derek and Marcus chased him by car and eventually forced his car to crash. Derek, at the mercy of Greene, was saved by Marcus, who killed Lucas Greene and ended his reign.

Cynthia Alive?
Marcus, during 2013, was given information that Cynthia was in fact still alive and that if he wanted to find her, he would have to take the three lives that the blackmailer told him. Marcus was eventually ordered to murder Derek, but couldn't kill him after realising he was becoming to much like Roman. Marcus and Derek eventually went and saw Roman, confirming to them that a victim of the Caesar Solomos case was in fact alive, but he didn't know if it was Cynthia or not. Roman escaped prison but was killed when Marcus found him. Marcus also learnt this day that it was in fact Greene's second in command who murdered Cynthia.

Marcus was kidnapped some weeks later by the same man who blackmailed him. Derek found him but was mortally wounded and the two discovered that it wasn't Cynthia who was alive, but rather Derek's old partner, Kale. Kale framed Derek and Marcus for the assassination of the Prime Minister, forcing them to go on the run. The two were on the run for an entire week before Marcus and Derek decided to go confront Kale. Upon confronting Kale, Marcus fought him and murdered him, avenging Cynthia's death. Upon leaving the house though Marcus was shot by a team outside who were there to arrest him and Derek. Marcus was shot twice and bled out quickly on the floor and died.

Personality
Marcus was a strong willed man who often acted before thinking. Marcus was easy to anger but had a strong heart and passion for his job. Cynthia's death changed Marcus and turned him into an arrogant man who had a thirst for revenge. Derek brought the old Marcus back, changing him from a drug addict into a kind hearted man. When it came to Cynthia's death and all the people surrounding him, he never second guessed his decisions and ultimately let his personal feelings get in the way of doing his job.

Derek Peterson
Marcus became partners with Derek in 2010 and served with him up until his death in 2013. Marcus and Derek often had arguments with each other, having a tight strain on their relationship. Their relationship improved however after Marcus returned from his secret assignment and the two became best friends. Marcus considered Derek his best friend but he never truly got away from his problems with Derek.

Cynthia Solomos
Cynthia is the love of Marcus' life. The two got together sometime before 2009 where Cynthia was helping the drug case against her brother Caesar. Marcus loved her however he often ignored her reasons toward him and his career. She was eventually kidnapped by Roman Duke and murdered by Kale Anderson. Marcus never moved on from Cynthia and he always loved her which ultimately brought him to his own death.

Roman Duke
Marcus had a strong hate toward Roman, believing him to be Cynthia's killer as he was Cynthia's kidnapper. Marcus, for years, wanted to kill Roman but could never find him. However he encountered Roman again but spared his life and arrested him. Soon Marcus learnt that Roman wasn't actually Cynthia's killer but his hate for him remained. When Roman escaped from prison, Marcus tracked him down and killed him.

Brad Fisher
Marcus became friends with Brad Fisher a couple of weeks after Cynthia's death. Brad was there for Marcus when no one else was and tried to help him get through his lose. Brad helped Derek on several cases involving Marcus to pay his friend back.
