Happy father's day from one of fantasy fiction's most infamous fathers; Tywin Lannister!
Tywin is the Lannister family patriarch in Game Of Thrones and definitely steers his family down their respective paths through the first half of the series.
In addition to Jaime and Cersi, Tywin is also father to Tyrion Lannister, known colloquially as "The Imp".
I've got to admit that even though he's not a character you're supposed to like I really enjoyed Tywin and in particular Charles Dance's portrayal of him on the show. In spite of the fact that you know he's a bad guy there are moments where you can't help but respect him.
And look at it it this way; at least he's not Denethor.
