I present to you Dexter Morgan. This is one of my favorite characters.
Dexter Morgan is a fictional character and an antihero of a series of novels by Jeff Lindsay, including Darkly Dreaming Dexter (2004), Dearly Devoted Dexter (2005), Dexter in the Dark (2007), Dexter by Design (2009), Dexter Is Delicious (2010) and Double Dexter (2011). In 2006, the first novel was adapted into the Showtime TV series Dexter and its companion web series Dexter: Early Cuts. A seventh novel written by Jeff Lindsay entitled Dexter's Debut is expected for release in late 2012.
In the television program, Dexter is played by Michael C. Hall. He has received rave reviews for his portrayal, both critically and popularly, and he won a Golden Globe Award in 2009 for Best Actor in a Television Series or Drama for his portrayal of Dexter Morgan in the fourth season.
