Simon Belmont is the protagonist of the 1987 Futabasha game book The Devil Castle Dracula: The Battle of Old Castle.
He is the descendant of the famous Simon Belmont, who defeated and sealed away Dracula in the 1500s and saved the fair Mina, in the 1950s. He is slated to portray his ancestor in The Devil Castle Dracula, a film adaptation about the original Simon's exploits, while his costar Lucy Lane was to portray Mina. Things go wrong, however, as their film crew unwittingly releases the seal on Dracula's tomb. Now, Simon must accomplish what his ancestor had and defeat Dracula once again.
- Despite being an official character, Simon Belmont is alternate to the Konami original Castlevania timeline.
