Five years after the Invasion of Planet P, her unit was on an Arachnid planet deep in the Arachnid Quarantine Zone and forced into a retreat to Hotel Delta 1-8-5, an abandoned Fortress Outpost. The unit was able to get to Hotel Delta 1-8-5 and held off several Arachnids attacks until the base's defences came online.
Dede Rake maintained the running of the base whilst they waited for retrieval. However, the base had become infected with Control Bugs and Rake was pinned down with a Control Bug forced into her mouth to take control of her body. Having infecting her, the Bugs ignored Rake, not noticing that the Sergeant had stabbed herself with multiple syringes to slow down the control over her body by the Bug. She got into a fight against the infected troopers around her, killing several. She eventually committed suicide after rescuing Lei Sahara and Captain Dax, who was being held prisoner.
- Although never mentioned onscreen, it was intended that Dede Rake was to be Captain Deladier's twin sister. Director Phil Tippet said that it was his biggest mistake to not include that scene.
