WMG / Sandokan

The novels are in the same universe as the Twenty Thousand Leagues Under the Sea novel
Twenty Thousand Leagues Under The Sea features Submarine Pirates whose side arms are air guns firing glass bullets with capacitors that shock the target to death in the 1868, the Sandokan novel The King of the Sea has a Death Ray that blows up warship munition magazines, and both Nemo and Sandokan are madmen fighting The British Empire (the main difference being that Sandokan gets saner during the course of The Tigers of Mompracem and is in full control of his faculties by his reappearance in The Pirates of Malaysia, while Nemo slowly goes madder).
  • Spanish author Fernando Savater actually conjectures in an essay that Captain Nemo was Sandokan's son, pursuing his father's anti-British rebellion with more advanced technology.
