A CBBC children's series from Russell T. Davies and Phil Ford, and something of a Spiritual Successor to The Sarah Jane Adventures, given that it was made by many of the same producers and writers of the earlier series, which was cancelled due to the death of its star. One episode of this series was actually based upon an unproduced SJA script.The premise is Exactly What It Says on the Tin - the evil magic-eating Nekross have come to Earth, the last source of magic in the entire universe, to seek new sources of magic to consume. They are opposed by young wizard Tom, his Muggle friend Benny, and Tom's eccentric grandmother Ursula.
This show provides examples of:
Adipose Rex: The Nekross King - we only ever see his vast head.
Co-Dragons: Varg and Lexi often play this role to their father, the Nekross King, though not strictly heirarchally - there are others of more authority and political power under him, so the siblings are generally Those Two Bad Guys and The Heavy more of the time. Lexi's apparent Heel-Face Turn in the Season 2 finale has uplifted this though.
Covered in Gunge: Aliens that explode in showers of orange goo when killed? Check.
Darker and Edgier: This show might be geared towards children, but the tone is positively bleak at times (see Downer Ending below) and can be shockingly frightening with high stakes each story arc. Notable because the show it follows in the footsteps of, The Sarah Jane Adventures, could also get similarly gritty tonally and make a mess of one's emotions, but this one takes it further with more adult themes and even less restraint in leaving the audience feeling broken down (though admittedly one of the stories, The Thirteenth Floor, was originally an SJA story before being rewritten to fit into this universe and setting). It also has a more continuous Story Arc with the Nekross always being present, as opposed to the Monster of the Week stories of the other show (though it had story arcs of its own, they were looser and the two-parters were more self-contained aside from some recurring villains and Foreshadowing).
Downer Ending: Stories such as 100 Wizards and The Thirteenth Floor must be viewed with tissues at hand. The latter's depressing ending is later rectified in the next story, with Tom and Lexi's memories of the 20 years they spent in the Neverway being restored, and then the Season Finale gives Tom the power to fix it completely - he saves Lexi's life by truly making her human, and he brings their son, Benny Junior, back into existence. So the original Downer becomes, by all appearances, an Earn Your Happy Ending for Lexi and her son, though it's unclear about their presence in Tom's life (as he's still fighting the Nekross and might be keeping his distance to protect them... making it a Bittersweet Ending at the worst.)
Enemy Mine: The heroes and Varg team up after Tom and Lexi are kidnapped:
Fantastic Racism: The Nekross seem to share the prejudices humans suffer from concerning skin color. The orange-skinned royal Varg, upon finding out the red-skin Jathro is the son of the white skin Kooth, brands it as 'blasphemy'. Benny rhetorically asks what's wrong with it.
Spiritual Successor: To The Sarah Jane Adventures, as the series was produced after Sarah Jane's actress passed away. One storyline, "The Thirteenth Floor", was adapted from an unfilmed Sarah Jane script and many behind-the-scenes personnel were carried over. Word of God is that the series was commissioned when it became known that Sarah Jane star Elisabeth Sladen's health was going to delay production of her show; it became a permanent replacement when Sladen died and the BBC retired SJA.
Teleport Interdiction: Magical teleportation can't breach the hull of the Nekross' ship. Justified, since they feed on magic.
