 Kraven the Hunter was first introduced into the Spider-Verse in Amazing Spider-Man #15. The much lauded hunter is solicited by his old friend the Chameleon to dispose of Spider-Man. The Chameleon did not think that he was up to the task of taking on Spidey by himself and that Kraven would "relish the task" of taking on a foe like Spider-Man. However, Kraven is unsuccessful and after Spider-Man defeats him, Kraven is deported from the country. Kraven soon returns though in Amazing Spider-Man #34, seeking revenge upon the wall crawler. The hunter impersonates Spidey and attacks J. Jonah Jameson in an attempt to get the real Spider-Man's attention. Spider-Man eventually defeats Kraven again, leaving the hunter webbed up and in police custody. However, it is soon revealed that the events as shown in Amazing Spider-Man #15 and #34 were not the full story and that Kraven was not working solely for his own gratification.  In a flashback sequence depicted in Amazing Spider-Man #47, we see a different recount of events between Amazing Spider-Man #15 and Amazing Spider-Man #34. In fact, the motivation for Kraven to snare Spider-Man was largely due to a $20K bounty the Green Goblin had placed on Spider-Man's head. But since Kraven rationalizes that he is much stronger than Spider-Man and that Spidey's defeat is imminent, he approaches the Goblin's "go-between" and demands half of the reward up front. The front man for the Goblin doesn't budge and suggests that if Kraven wants to renegotiate, he should do it with the Green Goblin directly. Kraven is angered by this refusal and soon swears vengeance upon the Green Goblin as well. Eventually, he tracks the "go-between" and finds his identity to be Norman Osborn. Unfortunately for Kraven, before he can exact punishment on Spider-Man or the Green Goblin he is defeated by the wall crawler as per the events of Amazing Spider-Man #34.
This brings us to the present time in Amazing Spider-Man #47, where a vengeful Kraven seeks to collect from the Green Goblin the money he "owes [him]…for the time [he] spent in jail". To Kraven's dismay, he discovers that the Green Goblin has died in a fire, as seen in Amazing Spider-Man #40. This news leaves Kraven with the only option of demanding the money from the Goblin's "go-between", Mr. Norman Osborn. Kraven is unable to find Norman though, and after threatening Norman's butler, the hunter settles on abducting his son Harry to draw Norman out of the woodwork. Norman soon gets wind that Kraven is causing a stir at midtown and immediately takes a taxi cab to that location. When Norman arrives, he sees Spider-Man battling Kraven, but the hunter immediately recognizes Norman and goes after him instead. However, Kraven soon becomes convinced that Norman does not know anything about the Green Goblin nor the money he owes Kraven. At this point, Norman is still experiencing amnesia regarding his Goblin persona. Kraven claims that he can "sense" when someone is lying, and he believes Norman to be telling the truth.  Since Kraven is a man of honor, he will not attack a person that he has no reason to attack, he therefore lets Norman go unscathed. However, before Spider-Man can detain Kraven, he is preoccupied with Norman, who somehow managed to fall from ledge of the scaffold that he was on. Spidey saves Osborn before he plummets to his death and he reunites him with his son. Interestingly, Norman blatantly defends Spider-Man to his friend J. Jonah Jameson, who believes Spidey tried to murder Osborn.
As an aside, in the retconned story Spider-Man: Blue #6, Norman actually thanks Spider-Man personally for saving himself and his son from the madman Kraven.
In a different retconned story featured in the Amazing Spider-Man 1996 Annual, which takes place some time after the events of Amazing Spider-Man #47, Norman continues his association with Kraven. Osborn offers him a great deal of money as well as an alliance, assuring the hunter that he will someday control a vast worldwide empire. However, Kraven feels dishonored by Norman’s recent actions and ends their brief alliance.
 One interesting facet to the Goblin mythos that is introduced in Amazing Spider-Man #47 is that Norman meets Peter for the first time in this book. However, this could be viewed as a continuity flub because Norman had supposedly met Peter already in the retconned story. Although certainly a great deal of time passed between those two events, so its possible that Norman had just forgotten that he had already met him.
