Nick Mulligan considered himself 'an undiscovered star' and occasionally went into a fantasy about being a rock star. He was part of a garage band called 10W40. He played the tambourine and was also learning the guitar in #473: “Breaking Point”. Nick used to live in New York, but he got into some trouble and was taken in by his uncle, Mike Mulligan. He then went to live with the Mulligans and worked at Whit's End. Although he did receive salvation on the audio show, he became a Christian in a non-canon Clubhouse Magazine story. Nick seemed to have a sense of honor and chivalry as he considered Rodney Rathbone a bully and loser and even confronted him about it. He has made Rodney back off as he has defended both Nathaniel Graham and Grady McKay before. After High School, Nick became estranged from his family when he attended New York City College and dated Erica Colburn. He eventually made amends with his family after an encounter with Aubrey Shepard at a gas station at Christmas time.
