Life Model Decoys
Years later, the Chameleon, working for Harry Osborn, created Life Model Decoys of Richard and Mary. These LMDs were near-perfect robotic replicas of Peter's dead parents, and managed to convince him that they had in fact been held captive overseas for most of his life.[3] Aunt May retains some suspicions, as there are some things they did not know, such as Richard and Mary's elopement. When Peter discovers that they were fake,[4] he suffers a nervous breakdown. When the Decoys were ordered to attack Parker, Mary's feelings for Peter causes her to save him. Neither LMD survives the incident. After battling the Chameleon, Spider-Man discovers that Harry Osborn was behind the whole thing, as an effort to avenge his (supposedly) dead father, Norman Osborn.[5] Spider-Man then becomes mentally unhinged over time, until he has a near-death experience.[volume & issue needed]
May Parker eventually learns the truth about the Life Model Decoys, via learning the truth about Spider-Man. May draws strength by talking to the graves of Mary, Richard and Ben about Peter's life.
