Ultimate Spider-Man, Vol. 1 #102

Peter is about to be subjected to Nick Fury's odd weapon when he is rescued by Spider-Woman. While on the way to the Oscorp factory MJ is being held in, Spider-Woman explains that she's just one in a successful series of cloning experiments using Peter Parker's DNA, obtained from Ben Reilly. (See issue #64.) They arrive to find that one of the clones has injected MJ with Oz, so she can defend herself and be with Peter. This is almost as surprising as the identity of the individual who provided the Oz.
