In July 2010, Shepherd's casting as Michael Moon, the psychopathic cousin of Alfie Moon, in EastEnders was announced. He made his first appearance on 1 October 2010 after Alfie's return. The character was the father of Tommy Moon, whose mother is Alfie's wife Kat Moon (Jessie Wallace) and later Scarlett Moon, daughter of Janine Butcher (Charlie Brooks). Michael is later joined by his father Eddie Moon (David Essex) and half brothers Tyler (Tony Discipline) and Anthony (Matt Lapinskas). A psychopath, Michael is described as a competitive and manipulative risk-taker who lives dangerously. He is a charmer with an eye for the ladies, but is willing to stab anyone in the back. In May 2011, Shepherd was nominated in the Best Soap Newcomer category at the 2011 TV Choice Awards for his portrayal of Michael. Michael has a relationship with Roxy Mitchell (Rita Simons), which is disliked by Roxy's sister Ronnie (Samantha Womack), and marries Janine Butcher (Charlie Brooks). Janine left Walford without Michael and Scarlett, leaving her daughter in the sole care of Michael. Michael struggles to look after his daughter and later hires Alice Branning (Jasmyn Banks) as her nanny. Janine returns several months later for Scarlett, and manipulates Michael into giving her custody, denying him access to Scarlett. In March 2013, Shepherd announced that he would be leaving EastEnders later that year. Shepherd's final storyline surrounded Michael's plan to murder Janine, with the help of a manipulated Alice. Michael's last episode was on 1 November 2013, when Alice tells Janine of the plot and when she confronts him, Michael attacks her and is then killed by Janine. In reality, Shepherd quit to explore new roles. Michael's funeral took place on 19 November 2013.
