Leroy Tallon was one of three possible suspects that the computer W.H.O identified as the possible murderer of W.H.O co-creator Dr Armstrong Smith. Spider-man tracked Leroy to his hideout and the two fought after Leroy admitted to committing a crime at the time of the murder. After a brief fight, Spider-man discovered that Leroy had killed Dr Smith but instead had robbed a Diamond Exchange at the time of the murder. Spider-man then webbed Leroy up for the police to arrest.
