Glover has previously played Lex's dad, Lionel, but he'll be appearing sometime this spring as the man who helped bring Heroes' antihero to life, a rep for the show confirmed to TVGuide.com.
The arrival of the new father-figure will pose some challenges for Sylar, who's already had daddy issues to contend with in recent episodes. "When Sylar meets his father, he's going to see a path ahead of him that he doesn't want to take," a source tells EW's Ausiello, who first reported the casting. "He has a lot more in common with his father than he realized."
In the interim before his Heroes arrival, Glover fans can find him on ABC's Brothers & Sisters. The actor was cast this fall for an arc as Saul's (Ron Rifkin) main squeeze.
Are you ready for some Luthor-style fathering for Sylar? What kind of impact do you hope he'll have on Heroes?
