Kirkwood compared Michael to Ronnie and Roxy's father, Archie Mitchell (Larry Lamb), saying they approach life and treat people in similar ways. The EastEnders website additionally calls Michael a "sinister", "flashy" and "jealous" man who "wouldn't think twice about screwing people over—even those he loves".
