What is the full name of Penny’s father in the TV series Lost?

Penny’s father in the TV series Lost is Charles Widmore.

Charles Widmore is a wealthy industrialist and former leader of the Others. He is also the father of Penelope “Penny” Widmore, whose relationship with Desmond Hume becomes one of the series’ major emotional storylines.

Widmore’s history connects him to the island long before the crash of Oceanic Flight 815. He was exiled from the island by Benjamin Linus and later spent years trying to find it again. His motives remain complicated because he claims to want to protect the island while also pursuing personal power and revenge.

Charles Widmore is sometimes confused with the other powerful older men in Lost, including Richard Alpert and Anthony Cooper. Unlike them, Widmore is specifically Penny’s father and Desmond’s determined adversary.
