The updated bronze Dalek design introduced in this episode would continue to be used right up to the end of Jodie Whittaker’s run as the Doctor, becoming the template for countless toys and many other products. In 2007 there were two releases in the action-figure range that directly tied in to this story, however. The Dalek with Mutant Reveal featured a front section that could be pulled away to expose the Kaled creature within, while the Genetic Print Dalek featured a red handprint on the front of its dome. Representing the spot where the lone creature was touched by Rose Tyler, this scarlet imprint could be made to temporarily vanish by applying the heat of a fan’s own palms.
