Gina Scalzi was one of the "angels of death" created by Sutekh to destroy the universe. When the Doctor's TARDIS landed on the Baby Station Beta in 21506, Sutekh used the power of the TARDIS' perception filter to retroactively create her. Like Sutekh's other angels, she was a real person, but would be transformed into one of Sutekh's servants when the time came. (TV: Empire of Death [+]Russell T Davies, Doctor Who series 14 (BBC One and Disney+, 2024).)
Scalzi was a comms officer in the crew of the Baby Station Beta, who protested against the corporation and quit the space station on Pacifico date 56-56-22, about 6 years before 21506. (TV: Space Babies [+]Russell T Davies, Doctor Who series 14 (BBC One and Disney+, 2024).)
The Fifteenth Doctor later recognised her as resembling the same woman as others he and Ruby Sunday encountered across their travels, (TV: The Legend of Ruby Sunday [+]Russell T Davies, Doctor Who series 14 (BBC One and Disney+, 2024).) not realizing that all of them were Sutekh's creations.
Following Sutekh's manifestation on Earth in 2024, Scalzi was transformed into an angel of death and brought the Dust of Death to her world. When Sutekh was defeated she and the other angels were returned to normal. (TV: Empire of Death [+]Russell T Davies, Doctor Who series 14 (BBC One and Disney+, 2024).)
