Scootori Manista was a trainee maintenance officer who was posted on Sanctuary Base 6. Scooti was twenty years old. Scooti was in the control room when the Tenth Doctor and Rose Tyler arrived.
Later, Scooti went into Toby Zed's room to drop off his expedenditure, and hears the opening and closing of the airlock. She ran out of the room and into the cooridor through Door 40. She raced over to the control panel. Her worries were confirmed when the computer told her that it had opened and closed the airlock. When Scooti asked if someone went out, it confirmed this, but it didn't know who went out and that no space suit had been taken. Frustrated, Scooti tries to contact Zach, but gets static. When she tries to talk to the computer again, it begins speaking about the Beast. Rattled, Scooti backs away from the door and a viewport begins to open down the hall.
Scooti walked down the hall to look through the view port. There she saw Toby, possessed by the Beast, standing outside, unprotected in the vacuum of space. Scooti's eyes widen in shock at this. Toby then turns around and sees her and then gives her a menacing smile. Scooti, in complete shock, mutter how this is impossible. However, Toby cuts her off. He begins motioning her towards him by waving his finger.. Scooti raised her arm towards him, helpless to refuse, and her eyes begin to moisten. This continues for a moment, before her eyes break away and stares at her arm. Her arm then drops. With force in her voice, Scooti pleads for Toby to stop.. After her refusal of him, Toby's smile disappears. The Toby then clenches his fist and sounds of glass breaking fill the cooridor. Scooti searches frantically for the source. Then a large crack appears on the glass between her and the deadly vacuum. Scooti gasps in shock and horror upon realizing Toby's intent. She then rushes for Door 40, and frantically tries to open. Her cries go unanswered, and the window shatters and Scooti is blown into space screaming. (DW: The Impossible Planet)
