Marcus
Background
Marcus is a mall elf for the Santa display and a thief. He is married to Lois.
During the events of Bad Santa (2003) played by Brett Kelly
Marcus hands a printed photo to Milwaukee Mom with Photo, which shows Willie staring at the ground and her daughter staring off to the side, and Milwaukee Mom with Photo declines to buy more copies. After the last kid is done, Marcus walks over to Willie and notices Willie peed himself. Milwaukee Security Guard initiates the mall store alarm system and a timer starts. Marcus, who was hiding as a snowman in the Christmas display runs to the alarm and turns it off. He opens the back door and lets Willie in and Willie starts breaking into the safe while Marcus grabs items from the store based off of a list he has. Willie gets the safe open and they gather the money and get into a van driven by Lois and drive away. Willie and Marcus go to a bar and Willie buys Marcus a shot from Milwaukee Bartender. Marcus tells Willie he is taking longer to break open the safes and Willie tells him he is going to retire and buy a bar on the beach in Miami. Marcus doesn't believe him and tells Willie, he is just going to drink his money away.
Several months later at Miami Beach, Willie listens to his phone messages and gets one from Marcus, who tells him to meet him in Phoenix. Several days later, in Phoenix, Arizona, they walk to their first day of work. Harrison calls Willie and Marcus hacks and Bob Chipeska introduces himself to them. Willie overhears Chipeska talk about their performance and accuses him of talking about his genitalia. Marcus is forced to try and smooth things over and blames Willie's comments on low blood sugar. Marcus tries to get the kids excited and asks Photo Elf if she has seen Willie. Photo Elf tells him Willie is in the back drunk. Marcus goes and yells at Willie and tells him to act professional. Nintendo Deer Hunter 3 Boy sneezes ice cream all over Willie's face and then asks for a Nintendo Deer Hunter game. Barbie Girl is next and after she asks for a Barbie Girl, she accidentally steps on Willie's foot. Fraggle-Stick Boy is next and he asks for a Fraggle-Stick car, which confuses Willie and Marcus. The Kid is eventually next in line to see Willie. The Kid keeps on asking questions and Willie tells Marcus to get him away from him.
A few days later, Chipeska brings Willie and Marcus into his office and says he caught one of them having sex with a woman in the changing room. He attempts to fire them, but Willie and Marcus threaten to sue him for unfair practices and then leave his office. While walking through the food court, Marcus sees Willie flirting with Pinball Girl. Willie and Marcus put Willie's safe cracking equipment in his Santa sack and are stopped by Phoenix Security Guard who refuses to let them in before exactly 8 am. Marcus crawls through the duct system until he gets to the security camera room and writes down all the makes and models of the equipment. Gin walks up to Marcus and then he, Willie and Marcus have a meeting that evening. He tells them he knows what they do and demands a 50% cut on the money they steal and they reluctantly agree. The next morning, Willie comes to work heavily intoxicated as a group of children stare in shock, forcing both Marcus and Gin to cover for him. Willie beats up Skateboard Bully and tells Marcus what he did and then they try to train The Kid how to fight.
A few days before Christmas, Marcus and Lois set a trap for Gin, and act like their car has broken down. As Gin goes to help them, Lois rams him with the van and then Marcus puts the jumper cables on Gin's ears, killing him. The night before Christmas, Chipeska announces that the store will be closing in five minutes as Phoenix Security Guard wishes everyone a Merry Christmas, including Lois, who positions a table of shirts under an air duct opening. Marcus climbs into the air ducts and turns off the security cameras before rushing over and turning off the alarm system the Phoenix Security Guard set. As Willie breaks into the safe, Marcus steals items from Lois' list. Willie gets the safe open and then goes to get The Kid a pink elephant and after he gets it, Marcus pulls a gun on him and tells him, he and Lois killed Gin. As Marcus is about to shoot Willie, Police Chief and a group of police order Marcus to drop his weapon. A shootout starts and Marcus and Lois eventually go to prison.
