Deirdre Bowman was the mother of Cathy Bowman. She appeared at the very beginning of the The Lost World: Jurassic Park picnicking on a beach with her family and her husband, and Cathy's father, is named Paul Bowman. Deirdre wouldn't allow her own daughter to play and have fun on the beach, due to having an irrational fear of snakes. When Cathy is attacked by Compsognathus, we see Deirdre screaming in horror just before the scene cuts away.
Deirdre Bowman appears as a playable character in LEGO Jurassic World. In the game's retelling of the events of the second film, her daughter's encounter with the Compsognathus is absent and instead the Bowman Family's visit to Isla Sorna is depicted in two still photographs in Hammond's room when Hammond is talking to Ian Malcolm about the incident. In the first photo, Deirdre is sunbathing on their yacht and watching as her daughter is catching an octopus with a fishing pole. The second photo depicts Deirdre Bowman with her husband and daughter feeding a T. rex a hot dog despite a nearby Do Not Feed sign.
She is unlocked for purchase in Free Mode after the completion of the Main Story mission "InGen Arrival". After the mission is completed, she can be purchased from the character select menu in Free Mode, or alternatively an NPC of Deirdre can be found near the dock on Isla Sorna and by interacting with her the player is given the option to unlock her. Regardless of the method used it costs 40,000 Studs (LEGO currency) to unlock her for play.
Like most female characters in the game, Deirdre possesses the Agile ability which allows her to jump higher than male characters and allows her to use Pink/Blue LEGO objects to access new areas. She can also use her Scream ability to break LEGO Glass by screaming, an ability she shares with her daughter, Cathy. Her scream ability is a reference to her screaming upon seeing her daughter being attacked in the film. The several of the pieces of LEGO Deirdre (such as her main body and sun hat with hair) can be also be unlocked as character customization options.
