Seymour O'Reilly is a Marvel Comics character who first appeared in Amazing Fantasy #15.
He was a wisecracking, bully-wannabe who joined athlete Flash Thompson to pick on unpopular kids such as Peter Parker. When Spider-Man appeared throughout the years, Seymour was still a sort of harasser to Peter as time goes by; for instance, he began playing some pranks on Peter such as putting a "kick-me" sign on his back and trying to give him a "wedgie". He makes a final appearance in the Marvel Knights Spider-Man series in issue #7 where he once again troubles Peter and he meets his demise when he is killed by Angelo Fortunato, the son of crime boss Don Fortunato who became the new Venom. Peter and his wife Mary Jane Watson were testified regarding O'Reilly's death to the police who arrive at Peter's high school reunion due to O'Reilly's demise.
