Bio: Jennifer "Jenny" Stewart a.k.a. Wysper is a member of the vigilante group the Jury. Jennifer and her husband Ryan were Guardsmen at the Vault, a prison for superhuman criminals. Ryan was murdered during a prison riot by prisoner Luis Alvarez, the second Tarantula. After the murder of her husband Jennifer moved in with a roommate named Claire until receiving a notice for "jury duty".
The majority of the members of the Jury were also former Guardsmen at the vault. The Jury soon freed Luis Alvarez from a prison in Del Boca Dios. After their own version of a trial the Tarantula managed to free himself and was given the option to kill Wysper to gain his freedom. Wysper and Tarantula dueled and Wysper was poisoned. To gain the antidote Wysper had to kill Tarantula. At first she hesitated to do so until the Jury informed her that Tarantula had killed her husband Ryan. Wysper chose to snap Tarantula's neck and her joining of the Jury was made official.
Wysper was with the team when they lost their funding and were forced to work for Edwin Cord with the U.S. Agent as the Jury's new leader. The Jury fought the Thunderbolts and lost. Later they helped the Thunderbolts defeat the second Secret Empire.
