In one of the psychoscapes based on various eras of Dalek history which existed within the Dalek Dome, was a Dalek City ruled by a Dalek Emperor in (COMIC: Liberation of the Daleks [+]Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) what the Dalek Combat Training Manual designated a Type I casing, (PROSE: Dalek Combat Training Manual [+]Richard Atkinson and Mike Tucker, BBC Books (2021).) in a tableau based on the Great Hall of the Dalek City as it appeared during Operation Human Factor. (TV: The Evil of the Daleks [+]David Whitaker, Doctor Who season 4 (BBC1, 1967).) The Doctor once referred to him as the Old Skaro Emperor. (COMIC: "Part Fourteen: The Nightmare Ends" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).)
The Fourteenth Doctor recruited this duplicate Emperor to help him defeat the duplicate Golden Emperor. (COMIC: "Part Twelve: The Garden of Death" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).) The Emperor was initially unwilling to believe that his entire universe was a threatened construct, and lashed out at the Doctor, evidencing the ability to reach out at intruders in the throne room using retractable, metallic tentacles, an ability which surprised the Doctor. However, he came around to believing the truth of the Doctor's report and agreed to help after he learned that the Golden Emperor's Daleks had already drained the adjacent psychoscape, the Jungles of Spiridon Zone, and his reality would be next.
He ordered the Manufacturing Zone Supervisor to create a new cohort of black-topped Daleks equipped with short-range teleport units who could attack the Golden Emperor's Skaro. The Doctor then opened communications channel in the real world to all the trapped mutant specimens fueling the Dalek Dome with their dreams, except for Specimen Nine Lambda, the Golden Emperor's "dreamer"; this allowed the leaders of various other psychoscape Zones to communicate with the Type I Emperor's control room to strategise, forming the Dalek Alliance. (COMIC: "Part Thirteen: The Hell Gate!" [+]Part of Liberation of the Daleks, Alan Barnes, DWM Comics (Panini Comics, 2022-2023).)
Eager to destroy his rival the "False Emperor", the Type I Emperor had ordered the cohort to immediately target and assassinate the Golden Emperor upon landing in the Golden City Zone, which was not the Doctor's plan. Though the advance party managed to destroy the Golden Emperor's Black Dalek attendant, they were quickly destroyed, prompting the Type I Emperor to call in the full might of the Dalek Alliance. Teleporting to the Golden City Zone before the Golden Emperor could evacuate, the Doctor warned him that the other Emperor had supposedly sent a Dalek Death Squad to the Dalek Dome to exterminate the Golden Emperor's mutant self. Having distracted the Golden Emperor, the Doctor then used the sonic screwdriver to override the control of the Emperor's rocketship and crash it into the Mathematicians' Moon, collapsing the Reality Gate and thus destroying all the Daleks who'd crossed out of their psychoscapes. With the situation resolved, the Doctor left the Dalek Dome, leaving it up to Georgette Gold whether to shut down the Dome or not.
