Sean Foley was the father of Richie Foley.
Sean Foley was an Irish-American man who hated African-Americans, a racist attitude that his son resented. His comments about Richie's best friend, Virgil Hawkins, caused Richie to run away. Ultimately, Sean swallowed his pride and asked Virgil's father for help. During their trip, he realized that he didn't really know that much about his son, and hadn't even assumed that Virgil was African American.
During their search, Robert Hawkins called him out on how he had driven Virgil away the previous night. Sean became embarrassed and tried to say that he wasn't trying to single out Virgil, but Robert bluntly told him that he might as well have been, as well as pointing out that his refusal to adapt to a changing world kept him from truly knowing his own son.
They found Richie in a warehouse, but they were trapped by Ebon. Static showed up, and during the fight, Sean helped Static against Ebon. When Ebon was subdued, Sean reconciled with his son and apologized for driving him away. Afterwards, he worked to overcome his racism for the sake of his son.
