During live shows, Marc is known for his frequent jump-kicks, and was also known for regularly wearing a backpack while playing live shows, although more recently he has stopped this practice. Marc has refused to reveal the contents of the backpack which has led to theories ranging from the bag being empty to containing the souls of his enemies. He is also known for occasionally wearing soccer shirts on stage, such as AC Milan and FC Internazionale. This can be seen at the Download Festival 2004. Marc holds the Guinness Book of World Records for 89 spin kicks in a single show.
