In this comic Spidey battles his clone which was created by the Jackal. The Jackal is revealed to be Peter Parker's Biology teacher Professer Warren....that's right his biology teacher...during the battle Spidey's clone has a change of heart (He is afterall Peter Parker's clone) and joins forces
with Spiderman to defeat the Jackal. In the process the clone is killed, the Jackal storyline ends, and Spiderman goes on with his life.
Nice clean ending or so it would appear. Unfortunately for Spiderman some 20 years later (2 or 3 in the Marvel Universe) it is revealed that the clone did not die. Worse yet he may actually be the real Peter Parker. At first this actually revitalizes Spiderman (who had grown a little stale) and made for some really interesting comics. This all changed of course when they revealed that the clone was in fact the real Peter Parker and that the Spiderman that fans around the world had grown to love was just a clone. Worse yet he was sent packing. Fans were less than impressed. In fact they actually staged a boycott of all the Spiderman titles until the real Spiderman (their Spiderman) was returned. The boycott was successful (depending on your point of view) and eventually Marvel gave in and quietly brought back the original Spidey.
While all this was going on the Author of Amazing Spiderman # 149 Gerry Conway stated that when he wrote the comic his intention was for the clone to die at the end of the story and nothing more, and that he never would have written it had he known that Marvel would revise the storyline as they did...Otherwise though it was kind of a cool little comic.
