After
The Halloween Apocalypse kicked off
Doctor Who: Flux in spectacularly manic fashion, it's now time to truly get into what series 13's continuous storyline has to offer. Despite the series only running for a total of six episodes and having its work cut out for it introducing new villain
Swarm, it wouldn't be
Doctor Who without some classic monsters making a reappearance.
War of the Sontarans marks the first title appearance of the cloned warrior race since 2008's
The Sontaran Stratagem/The Poison Sky, with subsequent appearances either having been cameos or centred around the commander turned nurse turned Paternoster Gang butler Strax. This episode however firmly re-establishes them as an enemy of the Doctor though, along with giving them a whole new look – again their first redesign since 2008.
