Darius Shan

Darius Shan is the son of Steve Leonard and Annie Shan. His best friend is Oggy Bas. He is described as having bright blue eyes and dark blond hair. In one book, Darren remarks that Darius is "an odd name", though if you consider it, it is most likely that Annie named Darius after her brother, Darren Shan.

Lord of the Shadows (book)
When he grew up, Steve often warped his son's mind, and said that Vampires are evil and carry the customs that Vampaneze did.

Sons of Destiny
Later, Darius realizes the truth, and hates his father for lying to him all these years. He was a half-Vampaneze, but Darren re-blooded him and he became a vampire, because he didn't want to become what his father was.

Personality
Darius is shown to have a more naive personality. However, being the son of Steve, and mentioned by Darren, Darius takes after his father. He's aggressive, convincing, and determined.
