Complete story — includes the ending
While faking being a doctor at a hospital, Billy notices a trio of mute, sinister businessmen known as "the Investors" stealing the heart of the dying King Gorilla. They kidnap him and take him to Monstroso, who treats Billy lavishly and arranges for him to have sex with a trio of prostitutes. Billy believes he is being groomed to be turned into a vampire, but Monstroso explains that he made a deal with King Gorilla for his heart upon his death, his own heart failing him, and he licenses Billy as a doctor so he can perform a heart transplant. Tracking the Investors through a homing device in Billy's hand, Brock and Shore Leave sneak on to Monstroso's yacht. The Investors easily escape them and Brock comes across Billy in the middle of surgery. Brock tries to convince him to let Monstroso die, but Billy insists upon finishing properly. Post-credits scene: Billy finishes the surgery and informs Brock, revealing they have moved to the S.P.H.I.N.X. compound. Brock asks if he can kill Monstroso.
