A cryogenic freezer-unit was device used to preserve corpses.
History[]
After Princess Taiyin of Mazam was exterminated by a Dalek, (COMIC: Abslom Daak... Dalek Killer) Abslom Daak placed her body into a cryogenic freezer-unit within "about" 20 minutes, hoping to someday find a medic capable of reviving her. (COMIC: Star Tigers, The Then and the Now) This unit was kept in Taiyin's space yacht, which Daak used to escape Mazam, ultimately landing on Draconia. Before leaving Draconia, Taiyin's unit was transfered to the Kill-Wagon, a prototype Imperial-class Frontier Defence Cruiser belonging to Prince Salander of Draconia. (COMIC: Star Tigers)
Ultimately, the Kill-Wagon was shot down and crash landed on the planet Hell, leaving Daak as the sole survivor of his crew. Taiyin's unit also survived, and was found by the Seventh Doctor. Daak himself seemingly perished as he destroyed the Daleks' Death Wheel. In gratitude, the native Helkans prepared a marked grave in which they buried Taiyin's body on the surface of Hell. (COMIC: Nemesis of the Daleks)
Later, Taiyin's body, still in the cyrogenic unit, was uncovered on Hell while Daak's crew were revived, supposedly by Helkan medicine. Just before his death, Daak was transmated to safety by the Emperor Dalek. Led to believe he had been saved by humans, Daak was given the task of finding the Doctor in return for Taiyin's revival. Capturing the Seventh Doctor and Bernice Summerfield on Hell, Daak's camp was transmated back to his benefactors, who had Taiyin's body taken to a special unit. Daak realised too late that he was actually on Skaro, and his benefactors were Dalek robots. Daak soon found Taiyin's body out of her cyrogenic unit, actually a trap prepared from the Daleks who had Taiyin's mouth emit gas which knocked out Daak and his company. After being made to fight Davros' Daleks on Spiridon, Daak returned to Skaro, where Davros usurped the Emperor Dalek. Daak was intent on rescuing Taiyin and, when he insisted on staying behind, the Doctor had his crew force him into the TARDIS. (COMIC: Emperor of the Daleks!)
Following the Last Great Time War, Daak was travelling with Taiyin's unit again. With no Daleks to kill, Daak took up a job to bring the Doctor to a judge for a trial. Using his vortex manipulator, Daak tracked down the Eleventh Doctor and occupied his TARDIS. In response to Daak's threat, the TARDIS hid Taiyin within its structure. Daak was then forced to join the Doctor in his quest to discover who killed the Cyclors. (COMIC: The Then and the Now)
After Daak was shot by the Squire (COMIC: Fast Asleep, Gently Pulls the Strings) Daak saw a vision of Taiyin, who hooked him up to a machine that healed his wounds. Daak then exited the TARDIS on a speeder and ran over the Squire. The Doctor then granted Daak his greatest wish, and used the Then and the Now to send him, ever accompanied by Taiyin's corpse, into the Last Great Time War, where he could slay Daleks to his heart's content.
