Characters

 * Dr. Robert Jekyll/Hyde, grandson of the Victorian Dr. Henry Jekyll/Edward Hyde and son of Captain Louie Jekyll/Hyde. As with most 'modern' Jekyll-and-Hydes, in his Hyde form, he possesses superhuman strength, speed, and an accelerated ability to heal.
 * Isabella "Bella" Charming, the owner of an East End night-club The Empire, who becomes the love interest of Robert's Hyde persona. She knows more than she originally seems to and provides Robert with information regarding Tenebrae. Feisty, kind, wise, jolly, sarcastic, and tough. A capable martial artist.
 * Lily Clarke Carew, a former biochemistry student ofCambridge taking care of her invalid mother who helps Robert study the medical side of his transformation and becomes his love interest.  Lily represents for Robert everything that is pure and good in the world. She selflessly looks after her invalid mother and is very kind and understanding and feisty, with a sophisticated metropolitan side that Robert at first finds unnerving – but nevertheless highly alluring.
 * Brigadier Sir Roger Bulstrode, a British Intelligence officer studying supernatural phenomena. A self-righteous, iron-fisted megalomaniac and fascist.
 * Garson, once Henry Jekyll's assistant/footman, now the bartender of The Empire nightclub, who knows the true nature of the connection between Jekyll and Hyde. Despite his age and knowledge of Hyde, he retains a certain affection for his former master that has been passed on to Robert, with Robert appreciating Garson's insight and knowledge into his grandfather's work.
 * Olalla Jeckyll/Hyde, Robert's sister who has a Hyde persona too. A deserter from Tenebrae.
 * Captain Louie Hyde/Jekyll, Robert and Ollala's dad who has a Hyde-persona. A soldier who fought alongside Lieutenant-Colonel T. E. Lawrence when they fought Turks during World-War 1.
 * Lord Omnitraz, the leader to Tenebrae. A demon-lord who was imprisoned by one of Jekyll's ancestors and seeks to be freed.
 * Major Dance, a senior member in Tenebrae. He is one of the living dead, capable of super-strength, super-speed, super-agility, and a healing factor. Dance is also capable of reviving corpses, turning them into the Vetala. Brunette with a goatee.
 * Captain Fedora, Dance's right hand and love-interest. A homicidal sociopath.
 * Lieutenant Silas Parnell, a Tenebrae-lieutenant. He lost one eye, and is the host for the Seeing Toad which allows him to see invisible or microscopic things as well as to see through other's eyes.
 * The Vetala, human-carcasses revived as assassins and pets for Tenebrae by Major Dance.
