- "Gombo, we burned the plantation, stole his ship and came looking for you."
- ―Marcus to Gombo
Marcus was a slave runaway that escaped and came to find his slave friend Gombo. He was the captain of the Ranger until he found Gombo aboard the Black Pearl. Marcus asked Gombo if he wanted to be the captain of the Ranger. Gombo accepted the offer and made Marcus the first mate. Gombo also took the name of their former master, becoming known as Jocard. Later Marcus helped distract King Samuel's men by steering a trick ship into the bay and setting it on fire. Afterwards he jumped off the ship without King Samuel's men seeing him and swam back to shore while the others broke into King Samuel's palace without being spotted.
