Helen is among the first members of the Shrike Team, the team being named after her hunter-like personality in battle. Like the rest of the team, she was assigned to protect Uso Ewin and his LM312V04 Victory Gundam.
When their transport plane is under attack by the Zanscare Empire, Helen and her teammates rush to defend it from the Empire's Tomliats. Helen was mainly in charge of aerial support, but she descended to pounce on a Tomliat when it got close to the plane and burned through it with her Gun-EZ's beam saber.
Unfortunately, the Tomliat mustered its last strength to punch directly at Helen's cockpit, crushing and killing her. Before she died, Helen was still able to shut off her unit's main engine and prevented an explosion near the plane. Peggy would be the one to tearfully report her death to the rest of the team.
Helen would be the first, but not the last, member of the Shrike Team to perish.
