Will Doctor Who’s Latest Spin-Off Redefine UNIT For A New Era?

UNIT May Not Only Have Sea Devils To Battle

While showrunner Russell T Davies' plan for arevolving UNIT castmakes Bingham’s return unsurprising, General Pierce’s appearance is more of a shock. Regarded as one of the Whoniverse’s darkest stories,Torchwood: Children of Earthsaw humanity forced into handing over 10% of Earth’s children to an alien menace, a dark bargain Pierce was left to enact and was almost blamed for by the UK Government. Save for Jack Harkness' (John Barrowman) self-imposed exile in space,Children of Earth’s dark events have never been referenced in the main show.

A military organization dedicated to protecting the Earth from alien threats, UNIT has been part of Doctor Who lore for a very long time.

As such, Pierce’s past pragmatic willingness to do what’s necessary to save humanity may not only suggest thatThe War Between the Land and the Seawill have a more mature tone, but also that there will be a deeper exploration of UNIT’s role. Despite Kate intending to lead with a science-first mandate, she has often found herself forced to take a more militaristic approach, andDoctor Whoseason 15might see UNIT become pariahs to the public. The spin-off may find UNIT trying to avert a full-blown war between the Sea Devils and the United States.
